Method Detail

__init

public void __init(int _i,
                   ByteBuffer _bb)

__assign

public Buffer __assign(int _i,
                       ByteBuffer _bb)

offset

public long offset()

The relative offset into the shared memory page where the bytes for this buffer starts

length

public long length()

The absolute length (in bytes) of the memory buffer. The memory is found from offset (inclusive) to offset + length (non-inclusive). When building messages using the encapsulated IPC message, padding bytes may be written after a buffer, but such padding bytes do not need to be accounted for in the size here.

createBuffer

public static int createBuffer(com.google.flatbuffers.FlatBufferBuilder builder,
                               long offset,
                               long length)
