Also offers basic text processing methods based on this function. + * Implementations are strongly encouraged to be side-effect-free and immutable. + * + *

Throughout the documentation of this class, the phrase "matching character" is used to mean + * "any {@code char} value {@code c} for which {@code this.matches(c)} returns {@code true}". + * + *

Warning: This class deals only with {@code char} values, that is, BMP characters. It does not understand + * supplementary Unicode code + * points in the range {@code 0x10000} to {@code 0x10FFFF} which includes the majority of + * assigned characters, including important CJK characters and emoji. + * + *

Supplementary characters are encoded + * into a {@code String} using surrogate pairs, and a {@code CharMatcher} treats these just as + * two separate characters. {@link #countIn} counts each supplementary character as 2 {@code char}s. + * + *

For up-to-date Unicode character properties (digit, letter, etc.) and support for + * supplementary code points, use ICU4J UCharacter and UnicodeSet (freeze() after building). For + * basic text processing based on UnicodeSet use the ICU4J UnicodeSetSpanner. + * + *

Example usages: + * + * 

+ *   String trimmed = {@link #whitespace() whitespace()}.{@link #trimFrom trimFrom}(userInput);

If the precondition is not met, the {@code Preconditions} method throws an unchecked exception + * of a specified type, which helps the method in which the exception was thrown communicate that + * its caller has made a mistake. This allows constructs such as + * + * 

{@code
+ * public static double sqrt(double value) {

+ *   }

+ *   checkArgument(value >= 0, "input is negative: %s", value);
+ *   // calculate square root

+ * + *

so that a hypothetical bad caller of this method, such as: + * + * 

{@code
+ * void exampleBadCaller() {
+ *   double d = sqrt(-1.0);
+ * }
+ * }
+ * + *

would be flagged as having called {@code sqrt()} with an illegal argument. + * + *

Performance

+ * + *

Avoid passing message arguments that are expensive to compute; your code will always compute + * them, even though they usually won't be needed. If you have such arguments, use the conventional + * if/throw idiom instead. + * + *

Depending on your message arguments, memory may be allocated for boxing and varargs array + * creation. However, the methods of this class have a large number of overloads that prevent such + * allocations in many common cases. + * + *

The message string is not formatted unless the exception will be thrown, so the cost of the + * string formatting itself should not be a concern. + * + *

As with any performance concerns, you should consider profiling your code (in a production + * environment if possible) before spending a lot of effort on tweaking a particular element. + * + *

Other types of preconditions

+ * + *

Not every type of precondition failure is supported by these methods. Continue to throw + * standard JDK exceptions such as {@link java.util.NoSuchElementException} or {@link + * UnsupportedOperationException} in the situations they are intended for. + * + *

Non-preconditions

+ * + *

It is of course possible to use the methods of this class to check for invalid conditions + * which are not the caller's fault. Doing so is not recommended because it is + * misleading to future readers of the code and of stack traces. See Conditional failures + * explained in the Guava User Guide for more advice. Notably, Verify offers assertions + * similar to those in this class for non-precondition checks. + * + *

{@code java.util.Objects.requireNonNull()}

+ * + *

Projects which use {@code com.google.common} should generally avoid the use of {@link + * java.util.Objects#requireNonNull(Object)}. Instead, use whichever of {@link + * #checkNotNull(Object)} or Verify#verifyNotNull(Object) is appropriate to the situation. + * (The same goes for the message-accepting overloads.) + * + *

Only {@code %s} is supported

+ * + *

{@code Preconditions} uses Strings#lenientFormat to format error message template + * strings. This only supports the {@code "%s"} specifier, not the full range of {@link + * java.util.Formatter} specifiers. However, note that if the number of arguments does not match the + * number of occurrences of {@code "%s"} in the format string, {@code Preconditions} will still + * behave as expected, and will still include all argument values in the error message; the message + * will simply not be formatted exactly as intended. + * + *

  1. Use sendfile(2) or equivalent. Requires that both the input channel and the output + * channel have their own file descriptors. Generally this only happens when both channels + * are files or sockets. This performs zero copies - the bytes never enter userspace. + *
  2. Use mmap(2) or equivalent. Requires that either the input channel or the output channel + * have file descriptors.

Note that if the file is very large, a naive + * implementation will effectively put the whole file in memory.

However, on systems where killing processes + * happens all the time in normal conditions (i.e., android) the OS must make a tradeoff + * between paging memory and killing other processes - so allocating a gigantic buffer and + * then sequentially accessing it could result in other processes dying. This is solvable + * via madvise(2), but that obviously doesn't exist in java. + *
  3. Ordinary copy. Kernel copies bytes into a kernel buffer, from a kernel buffer into a + * userspace buffer (byte[] or ByteBuffer), then copies them from that buffer into the + * destination channel. + *

The IPv4 loopback address, {@code "127.0.0.1"}. + *
{@code 7f 00 00 01} + *
The IPv6 loopback address, {@code "::1"}. + *
{@code 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 01} + *
From the IPv6 reserved documentation prefix ({@code 2001:db8::/32}), {@code "2001:db8::1"}. + *
{@code 20 01 0d b8 00 00 00 00 00 00 00 00 00 00 00 01} + *
An IPv6 "IPv4 compatible" (or "compat") address, {@code "::192.168.0.1"}. + *
{@code 00 00 00 00 00 00 00 00 00 00 00 00 c0 a8 00 01} + *
An IPv6 "IPv4 mapped" address, {@code "::ffff:192.168.0.1"}. + *
{@code 00 00 00 00 00 00 00 00 00 00 ff ff c0 a8 00 01} + *

A few notes about IPv6 "IPv4 mapped" addresses and their observed use in Java. + * + *

"IPv4 mapped" addresses were originally a representation of IPv4 addresses for use on an IPv6 + * socket that could receive both IPv4 and IPv6 connections (by disabling the {@code IPV6_V6ONLY} + * socket option on an IPv6 socket). Yes, it's confusing. Nevertheless, these "mapped" addresses + * were never supposed to be seen on the wire. That assumption was dropped, some say mistakenly, in + * later RFCs with the apparent aim of making IPv4-to-IPv6 transition simpler. + * + *

Technically one can create a 128bit IPv6 address with the wire format of a "mapped" + * address, as shown above, and transmit it in an IPv6 packet header. However, Java's InetAddress + * creation methods appear to adhere doggedly to the original intent of the "mapped" address: all + * "mapped" addresses return {@link Inet4Address} objects. + * + *

For added safety, it is common for IPv6 network operators to filter all packets where either + * the source or destination address appears to be a "compat" or "mapped" address. Filtering + * suggestions usually recommend discarding any packets with source or destination addresses in the + * invalid range {@code ::/3}, which includes both of these bizarre address formats. For more + * information on "bogons", including lists of IPv6 bogon space, see: + * + *

+ * This class implements section 6.8. Base64 Content-Transfer-Encoding from RFC 2045 Multipurpose + * Internet Mail Extensions (MIME) Part One: Format of Internet Message Bodies by Freed and Borenstein. + *

+ *

+ * The class can be parameterized in the following manner with various constructors: + *

+ *
    + *
  • URL-safe mode: Default off.
    • + *
  • Line length: Default 76. Line length that aren't multiples of 4 will still essentially end up being multiples of + * 4 in the encoded data. + *
  • Line separator: Default is CRLF ("\r\n")
    • + *
+ *

+ * The URL-safe parameter is only applied to encode operations. Decoding seamlessly handles both modes. + *

- * Note that this is not the same base58 as used by Flickr, which you may find referenced around the Internet. - *

- * Satoshi explains: why base-58 instead of standard base-64 encoding? - *

    - *
  • Don't want 0OIl characters that look the same in some fonts and - * could be used to create visually identical looking account numbers.
    • - *
  • A string with non-alphanumeric characters is not as easily accepted as an account number.
    • - *
  • E-mail usually won't line-break if there's no punctuation to break at.
    • - *
  • Doubleclicking selects the whole number as one word if it's all alphanumeric.
    • - *
- *

- * However, note that the encoding/decoding runs in O(n²) time, so it is not useful for large data. - *

- * The basic idea of the encoding is to treat the data bytes as a large number represented using - * base-256 digits, convert the number to be represented using base-58 digits, preserve the exact - * number of leading zeros (which are otherwise lost during the mathematical operations on the - * numbers), and finally represent the resulting base-58 digits as alphanumeric ASCII characters. - */ -public class Base58 { - public static final char[] ALPHABET = "123456789ABCDEFGHJKLMNPQRSTUVWXYZabcdefghijkmnopqrstuvwxyz".toCharArray(); - private static final char ENCODED_ZERO = ALPHABET[0]; - private static final int[] INDEXES = new int[128]; - static { - Arrays.fill(INDEXES, -1); - for (int i = 0; i < ALPHABET.length; i++) { - INDEXES[ALPHABET[i]] = i; - } - } - - /** - * Encodes the given bytes as a base58 string (no checksum is appended). - * - * @param input the bytes to encode - * @return the base58-encoded string - */ - public static String encode(byte[] input) { - if (input.length == 0) { - return ""; - } - // Count leading zeros. - int zeros = 0; - while (zeros < input.length && input[zeros] == 0) { - ++zeros; - } - // Convert base-256 digits to base-58 digits (plus conversion to ASCII characters) - input = Arrays.copyOf(input, input.length); // since we modify it in-place - char[] encoded = new char[input.length * 2]; // upper bound - int outputStart = encoded.length; - for (int inputStart = zeros; inputStart < input.length; ) { - encoded[--outputStart] = ALPHABET[divmod(input, inputStart, 256, 58)]; - if (input[inputStart] == 0) { - ++inputStart; // optimization - skip leading zeros - } - } - // Preserve exactly as many leading encoded zeros in output as there were leading zeros in input. - while (outputStart < encoded.length && encoded[outputStart] == ENCODED_ZERO) { - ++outputStart; - } - while (--zeros >= 0) { - encoded[--outputStart] = ENCODED_ZERO; - } - // Return encoded string (including encoded leading zeros). - return new String(encoded, outputStart, encoded.length - outputStart); - } - - /** - * Decodes the given base58 string into the original data bytes. - * - * @param input the base58-encoded string to decode - * @return the decoded data bytes - */ - public static byte[] decode(String input) { - if (input.length() == 0) { - return new byte[0]; - } - // Convert the base58-encoded ASCII chars to a base58 byte sequence (base58 digits). - byte[] input58 = new byte[input.length()]; - for (int i = 0; i < input.length(); ++i) { - char c = input.charAt(i); - int digit = c < 128 ?

- * This class implements section 6.8. Base64 Content-Transfer-Encoding from RFC 2045 Multipurpose - * Internet Mail Extensions (MIME) Part One: Format of Internet Message Bodies by Freed and Borenstein. - *

- *

- * The class can be parameterized in the following manner with various constructors: - *

- *
    - *
  • URL-safe mode: Default off.
    • - *
  • Line length: Default 76. Line length that aren't multiples of 4 will still essentially end up being multiples of - * 4 in the encoded data. - *
  • Line separator: Default is CRLF ("\r\n")
    • - *
- *

- * The URL-safe parameter is only applied to encode operations. Decoding seamlessly handles both modes. - *

- *

- * Since this class operates directly on byte streams, and not character streams, it is hard-coded to only - * encode/decode character encodings which are compatible with the lower 127 ASCII chart (ISO-8859-1, Windows-1252, - * UTF-8, etc). - *

- *
