Method Detail

createWithBase

public static MatrixByteBuffered2x2s32 createWithBase(ByteBuffer b,
                                                      com.io7m.mutable.numbers.core.MutableLongType base,
                                                      int offset)

Return a new vector that is backed by the given byte buffer b

The data for the instance will be taken from the data at the current value of base.get() + offset, each time a field is requested or set.

No initialization of the data is performed.

Parameters:

b - The byte buffer

base - The base address

offset - A constant offset

Returns:

A new buffered vector
