Method Detail

copyField

private byte[] copyField(ByteBuffer src,
                         int startOfField)

Given src.position() bigger than startOfField, allocate a fresh byte array, and copy the data from startOfField to src.position() into it.

Parameters:

src - the ByteBuffer to copy from

startOfField - the position of the buffer at which the field starts

Returns:

a copy of the data between startOfField and the buffer position before invokation

Throws:

IllegalArgumentException - if startOfField is somewhere after src.position()
