Constructor Details

StandardGradientPaintTransformer

public StandardGradientPaintTransformer()

Creates a new transformer with the type GradientPaintTransformType.VERTICAL.

StandardGradientPaintTransformer

public StandardGradientPaintTransformer(GradientPaintTransformType type)

Creates a new transformer with the specified type.

Parameters:

type - the transform type (null not permitted).

Method Details

getType

public GradientPaintTransformType getType()

Returns the type of transform.

Returns:

The type of transform (never null).

transform

public GradientPaint transform(GradientPaint paint,
Shape target)

Specified by:

transform in interface GradientPaintTransformer

Parameters:

paint - the original paint (null not permitted).

target - the target shape (null not permitted).

Returns:

The transformed paint.

equals

public boolean equals(Object obj)

Tests this instance for equality with an arbitrary object.

Overrides:

equals in class Object

Parameters:

obj - the object (null permitted).

Returns:

A boolean.

clone

public Object clone()
             throws CloneNotSupportedException

Returns a clone of the transformer. Note that instances of this class are immutable, so cloning an instance isn't really necessary.
