public class Matrix3x2dStack
extends Matrix3x2d

A stack of many Matrix3x2d instances. This resembles the matrix stack known from legacy OpenGL.

This Matrix3x2dStack class inherits from Matrix3x2d, so the current/top matrix is always the Matrix3x2dStack/Matrix3x2d itself. This affects all operations in Matrix3x2d that take another Matrix3x2d as parameter. If a Matrix3x2dStack is used as argument to those methods, the effective argument will always be the current matrix of the matrix stack.

Constructor Detail

Matrix3x2dStack

public Matrix3x2dStack(int stackSize)

Create a new Matrix3x2dStack of the given size.

Initially the stack pointer is at zero and the current matrix is set to identity.

Parameters:

stackSize - the size of the stack. This must be at least 1, in which case the Matrix3x2dStack simply only consists of this Matrix3x2d

Matrix3x2dStack

public Matrix3x2dStack()

Do not invoke manually! Only meant for serialization.

Invoking this constructor from client code will result in an inconsistent state of the created Matrix3x2dStack instance.

Method Detail

clear

public Matrix3x2dStack clear()

Set the stack pointer to zero and set the current/bottom matrix to identity.

Returns:

this

pushMatrix

public Matrix3x2dStack pushMatrix()

Increment the stack pointer by one and set the values of the new current matrix to the one directly below it.

Returns:

this

popMatrix

public Matrix3x2dStack popMatrix()

Decrement the stack pointer by one.

This will effectively dispose of the current matrix.

Returns:

this

hashCode

public int hashCode()

Overrides:

hashCode in class Matrix3x2d

equals

public boolean equals(Object obj)

Overrides:

equals in class Matrix3x2d
