A thread-safe Buffer pool that allows for the automatic reuse of Buffer
objects (including ByteBuffer
, CharBuffer
, etc.), which can be over 30x faster than having to allocate a new Buffer
.
- Add Pbbl as a dependency using either Maven or Gradle:
Maven:
<dependency>
<groupId>com.arenareturns</groupId>
<artifactId>Pbbl</artifactId>
<version>1.0.3</version>
</dependency>
Gradle:
implementation 'com.arenareturns:Pbbl:1.0.3'
- Because Pbbl is compiled with Java 11, you must require its module in your
module-info.java
:
module my.project {
requires com.arenareturns.pbbl;
}
- Create
ByteBufferPool
and manually close it:
// Create a ByteBufferPool (used to pool non-direct ByteBuffer objects).
var pool = new ByteBufferPool();
// Take a non-direct ByteBuffer (with 8 available bytes) from the pool.
// If the pool is empty, a new ByteBuffer will be created.
var buffer = pool.take(Long.BYTES);
// Do something with the ByteBuffer.
var array = buffer.putLong(42).array();
// Give the ByteBuffer back to the pool for re-use.
pool.give(buffer);
// Close the pool when finished.
pool.close();
- Create
DirectFloatBufferPool
and automatically close it:
// Create a DirectFloatBufferPool (used to pool direct FloatBuffer objects).
try (var pool = new DirectFloatBufferPool()) {
// Take a direct FloatBuffer (with 8 available floats) from the pool.
FloatBuffer buffer = pool.take(8);
// Do something with the FloatBuffer.
buffer.put(42f);
// Give the FloatBuffer back to the pool for re-use.
pool.give(buffer);
}
