Method Detail

returnBuffer

public void returnBuffer(byte[] buf)

Description copied from interface: IBufferManager

equals returnBuffer(buffer, false)

Specified by:

returnBuffer in interface IBufferManager

See Also:

IBufferManager.returnBuffer(byte[], boolean)

getPreferredMemoryBuffer

public byte[] getPreferredMemoryBuffer()

getPreferredMemoryBuffer returns a new buffer with the default (MEM_BUFSIZE = 1023) size. Method is used when there is no possibility to determine what exactly size of buffer is required. Thus, just create new buffer with the minimum cacheable size.

Specified by:

getPreferredMemoryBuffer in interface IBufferManager

Returns:

a byte[] value

See Also:

IBufferManager.getBuffer(int)

release

public void release()

Description copied from interface: IBufferManager

release all resources that are held by this buffer

Specified by:

release in interface IBufferManager

returnBuffer

public void returnBuffer(byte[] buffer,
                boolean b)

Specified by:

returnBuffer in interface IBufferManager

Parameters:

buffer - a byte[] value

b - a boolean value value to denote if CDROuputStream is caller (may use cache in this situation)

getExpandedBuffer

public byte[] getExpandedBuffer(int size)

Description copied from interface: IBufferManager

getExpandedBuffer returns a new buffer which size will be calculated according to BufferManager expansion policy.

Specified by:

getExpandedBuffer in interface IBufferManager

Parameters:

size - an int value

Returns:

a byte[] value
