Constructor Detail

ByteBufferPool

public ByteBufferPool(int poolSize,
                      int minimumCapacity,
                      int maxBufferSize)

Instantiates a new, empty ByteBufferPool.

Parameters:

maxBufferSize - - specifies the size of the (immutable) ByteBuffers that will be created within this pool.

Method Detail

clean

protected void clean(java.nio.ByteBuffer objectToClean)

Description copied from class: ResourcePool

Ensure that the given Object is "clean", that is, in the state it would be in if it were just instantiated. For example, if this class were handling StringBuilders, it should ensure that the StringBuilder does not contain any characters from a previous use. clean(T) is automatically called immediately before an object is returned from the acquire() method.

Specified by:

clean in class ResourcePool<java.nio.ByteBuffer>

generateNewResource

protected java.nio.ByteBuffer generateNewResource()

Description copied from class: ResourcePool

Instantiates a resource of type T.

Specified by:

generateNewResource in class ResourcePool<java.nio.ByteBuffer>

Returns:
