static String	DEFAULT_BUFFER_CAPACITY The default capacity of the allocated buffers.

static String	POOL_CAPACITY The capacity of the DirectBufferPool is the maximum #of direct ByteBuffer instances that may reside in the pool (default "2147483647").

Field Detail

POOL_CAPACITY

static final String POOL_CAPACITY

The capacity of the DirectBufferPool is the maximum #of direct ByteBuffer instances that may reside in the pool (default "2147483647").

Note: Placing a limit on the pool size could cause threads to deadlock awaiting a direct buffer from the pool. For this reason is it good practice to use DirectBufferPool.acquire(long, TimeUnit) with a timeout.

DEFAULT_POOL_CAPACITY

static final String DEFAULT_POOL_CAPACITY

The default pool capacity (no limit).
