Method Summary

Modifier and Type	Method	Description
@RawPtr Shader	getBase()
Matrixc	getLocalMatrix()
boolean	isConstant()	Returns true if the shader is guaranteed to produce only a single color.
boolean	isOpaque()	Returns true if the shader is guaranteed to produce only opaque colors, subject to the Paint using the shader to apply an opaque alpha value.
boolean	isTriviallyCounted()	A return value of true means that its ref/unref is unnecessary, for example, they are just no op.
void	ref()	Increases the reference count by 1.
void	unref()	Decreases the reference count by 1.

Method Details

ref

public void ref()

Description copied from interface: RefCounted

Increases the reference count by 1.

Specified by:

ref in interface RefCounted

Specified by:

ref in interface Shader

unref

public void unref()

Description copied from interface: RefCounted

Decreases the reference count by 1.

Specified by:

unref in interface RefCounted

Specified by:

unref in interface Shader

isTriviallyCounted

public boolean isTriviallyCounted()

Description copied from interface: Shader

A return value of true means that its ref/unref is unnecessary, for example, they are just no op. So callers can perform some optimizations. Subclass can override this method to indicate that an instance is trivially counted. For the same instance, the return value of this method must remain unchanged.

Specified by:

isTriviallyCounted in interface Shader

isOpaque

public boolean isOpaque()

Description copied from interface: Shader

Returns true if the shader is guaranteed to produce only opaque colors, subject to the Paint using the shader to apply an opaque alpha value. Subclasses should override this to allow some optimizations.

Specified by:

isOpaque in interface Shader

isConstant

public boolean isConstant()

Returns true if the shader is guaranteed to produce only a single color. Subclasses can override this to allow loop-hoisting optimization.

Specified by:

isConstant in interface Shader

getBase

@RawPtr
public @RawPtr Shader getBase()

getLocalMatrix

public Matrixc getLocalMatrix()
