Method Details

createWithBase

public static MatrixByteBuffered2x2s32 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 buffer

base - The base address

offset - A constant offset

Returns:

A new buffered vector

componentCount

protected int componentCount()

r0c0

public double r0c0()

Specified by:

r0c0 in interface MatrixReadable2x2DType

Returns:

The value at row 0 column 0

r0c1

public double r0c1()

Specified by:

r0c1 in interface MatrixReadable2x2DType

Returns:

The value at row 0 column 1

r1c0

public double r1c0()

Specified by:

r1c0 in interface MatrixReadable2x2DType

Returns:

The value at row 1 column 0

r1c1

public double r1c1()

Specified by:

r1c1 in interface MatrixReadable2x2DType

Returns:

The value at row 1 column 1
