Create a DataBuffer from a byte buffer. This is meant to be used with flatbuffers

Parameters:

bb - the flat buffers buffer

bb_pos - the position to start from

type - the type of buffer to create

length - the length of the buffer to create

Returns:

the created databuffer

createDataBufferStruct

public static int createDataBufferStruct(com.google.flatbuffers.FlatBufferBuilder bufferBuilder,
                                         org.nd4j.linalg.api.buffer.DataBuffer create)

Create a data buffer struct within the passed in FlatBufferBuilder

Parameters:

bufferBuilder - the existing flatbuffer to use to serialize the DataBuffer

create - the databuffer to serialize

Returns:

an int representing the offset of the buffer
