Method Details

expand

public static ByteBuffer expand(ByteBuffer in,
 int newSize)

Expands buffer to the given size unless it is already as big or bigger. Buffers are assumed to be in 'write to' mode since there would be no need to expand a buffer while it was in 'read from' mode.

Parameters:

in - Buffer to expand

newSize - The size t which the buffer should be expanded

Returns:

The expanded buffer with any data from the input buffer copied in to it or the original buffer if there was no need for expansion

cleanDirectBuffer

public static void cleanDirectBuffer(ByteBuffer buf)

Clean specified direct buffer. This will cause an unavoidable warning on Java 24 and newer.

Parameters:

buf - the buffer to clean
