Method Detail

getTransformNoClone

public BaseTransform getTransformNoClone()

Specified by:

getTransformNoClone in class TransformedShape

adjust

public BaseTransform adjust(BaseTransform transform)

Description copied from class: TransformedShape

Returns a new transform that represents the specified transform with the transform of this TransformedShape concatenated.

Specified by:

adjust in class TransformedShape

Parameters:

transform - the specified contextual transform

Returns:

the concatenated transform

getBounds

public RectBounds getBounds()

Description copied from class: Shape

Note that there is no guarantee that the returned RectBounds is the smallest bounding box that encloses the Shape, only that the Shape lies entirely within the indicated RectBounds.

Overrides:

getBounds in class TransformedShape

Returns:

an instance of RectBounds

contains

public boolean contains(float x,
                        float y)

Description copied from class: Shape

Tests if the specified coordinates are inside the boundary of the Shape.

Overrides:

contains in class TransformedShape

Parameters:

x - the specified X coordinate to be tested

y - the specified Y coordinate to be tested

Returns:

true if the specified coordinates are inside the Shape boundary; false otherwise.

intersects

public boolean intersects(float x,
                          float y,
                          float w,
                          float h)

Description copied from class: Shape

Tests if the interior of the Shape intersects the interior of a specified rectangular area. The rectangular area is considered to intersect the Shape if any point is contained in both the interior of the Shape and the specified rectangular area.

The Shape.intersects() method allows a Shape implementation to conservatively return true when:

• there is a high probability that the rectangular area and the Shape intersect, but
• the calculations to accurately determine this intersection are prohibitively expensive.

This means that for some Shapes this method might return true even though the rectangular area does not intersect the Shape. The Area class performs more accurate computations of geometric intersection than most Shape objects and therefore can be used if a more precise answer is required.

Overrides:

intersects in class TransformedShape

Parameters:

x - the X coordinate of the upper-left corner of the specified rectangular area

y - the Y coordinate of the upper-left corner of the specified rectangular area

w - the width of the specified rectangular area

h - the height of the specified rectangular area

Returns:

true if the interior of the Shape and the interior of the rectangular area intersect, or are both highly likely to intersect and intersection calculations would be too expensive to perform; false otherwise.

contains

public boolean contains(float x,
                        float y,
                        float w,
                        float h)

Description copied from class: Shape

Tests if the interior of the Shape entirely contains the specified rectangular area. All coordinates that lie inside the rectangular area must lie within the Shape for the entire rectanglar area to be considered contained within the Shape.

The Shape.contains() method allows a Shape implementation to conservatively return false when:

• the intersect method returns true and
• the calculations to determine whether or not the Shape entirely contains the rectangular area are prohibitively expensive.

This means that for some Shapes this method might return false even though the Shape contains the rectangular area. The Area class performs more accurate geometric computations than most Shape objects and therefore can be used if a more precise answer is required.

Overrides:

contains in class TransformedShape

Parameters:

x - the X coordinate of the upper-left corner of the specified rectangular area

y - the Y coordinate of the upper-left corner of the specified rectangular area

w - the width of the specified rectangular area

h - the height of the specified rectangular area

Returns:

true if the interior of the Shape entirely contains the specified rectangular area; false otherwise or, if the Shape contains the rectangular area and the intersects method returns true and the containment calculations would be too expensive to perform.
