Constructor Detail

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 Detail

getType

public GradientPaintTransformType getType()

Returns the type of transform.

Returns:

The type of transform (never null).

Since:

1.0.10

transform

public java.awt.GradientPaint transform(java.awt.GradientPaint paint,
                                        java.awt.Shape target)

Transforms a GradientPaint instance to fit the specified target shape.

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(java.lang.Object obj)

Tests this instance for equality with an arbitrary object.

Overrides:

equals in class java.lang.Object

Parameters:

obj - the object (null permitted).

Returns:

A boolean.

clone

public java.lang.Object clone()
                       throws java.lang.CloneNotSupportedException

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

Specified by:

clone in interface PublicCloneable

Overrides:

clone in class java.lang.Object

Returns:

A clone.

Throws:

java.lang.CloneNotSupportedException - not thrown by this class, but subclasses (if any) might.

hashCode

public int hashCode()

Returns a hash code for this object.

Overrides:

hashCode in class java.lang.Object

Returns:

A hash code.
