createWithBase
public static MatrixByteBuffered2x2s64 createWithBase(java.nio.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 bufferbase
- The base addressoffset
- A constant offset- Returns:
- A new buffered vector
-
