/**
 * A value for a QueryParameter along with its type.
 *
 * <p>A static factory method is provided for each of the possible types (e.g. {@link #int64(Long)}
 * for StandardSQLTypeName.INT64). Alternatively, an instance can be constructed by calling {@link
 * #of(Object, Class)} with the value and a Class object, which will use these mappings:
 *
 * <ul>
 *   <li>Boolean: StandardSQLTypeName.BOOL
 *   <li>String: StandardSQLTypeName.STRING
 *   <li>Integer: StandardSQLTypeName.INT64
 *   <li>Long: StandardSQLTypeName.INT64
 *   <li>Double: StandardSQLTypeName.FLOAT64
 *   <li>Float: StandardSQLTypeName.FLOAT64
 *   <li>BigDecimal: StandardSQLTypeName.NUMERIC
 *   <li>BigNumeric: StandardSQLTypeName.BIGNUMERIC
 *   <li>JSON: StandardSQLTypeName.JSON
 *   <li>INTERVAL: StandardSQLTypeName.INTERVAL
 * </ul>
 *
 * <p>No other types are supported through that entry point. The other types can be created by
 * calling {@link #of(Object, StandardSQLTypeName)} with the value and a particular
 * StandardSQLTypeName enum value.
 *
 * <p>Struct parameters are currently not supported.
