Method Detail

create

public ByteBuffer create()

Specified by:

create in interface ObjectManager<ByteBuffer>

prepareForRecycle

public boolean prepareForRecycle(ByteBuffer buf)

Description copied from interface: ObjectManager

Prepare an object to be reused by a different user. Implementations of this method must make sure that any data from previous users is cleared.

Specified by:

prepareForRecycle in interface ObjectManager<ByteBuffer>

Parameters:

buf - The object which must be prepared for reuse.

Returns:

true if this object can be reused, false otherwise (for example if the size of the offered buffer is too small). After returning false ObjectManager.release(Object) will be called.

release

public void release(ByteBuffer buf)

Specified by:

release in interface ObjectManager<ByteBuffer>

canReuse

public boolean canReuse(ByteBuffer buf)

Specified by:

canReuse in interface ObjectManager<ByteBuffer>

Parameters:

buf - -

Returns:

true if this pooled object can be reused, false otherwise. Example: The pooled object is a database connection which might not be reusable because the connection was closed while being in the pool.
