Class XyShapeList<T extends XyShape>

java.lang.Object
  com.partnersoft.geometry.xy.XyShapeList<T>

All Implemented Interfaces:

Immutable, XyShape<XyShapeList>, java.lang.Iterable<XyPoint>

public class XyShapeList<T extends XyShape>
extends java.lang.Object
implements XyShape<XyShapeList>

An ordered list of XyShapes. Useful for handling nonhomogenous collections of shapes, or for dealing with the results when regular shapes get demolished by cropping or transformations.

XyShapeList

public XyShapeList(java.util.List<T> shapes)

Method Detail

listShapes

public java.util.List<T> listShapes()

getBounds

public XyBounds getBounds()

Description copied from interface: XyShape

Returns an XyBounds object representing the rectangular extents of this shape.

Specified by:

getBounds in interface XyShape<XyShapeList>

scaledBy

public XyShapeList<T> scaledBy(double factor)

Description copied from interface: XyShape

Return a scaled version of the shape by multiplying all coordinates by the given factor in both dimensions. This resulting shape must be of the same class as the original.

Specified by:

scaledBy in interface XyShape<XyShapeList>

Parameters:

factor - scaling factor

Returns:

scaled result

transformedBy

public XyShape transformedBy(XyTransform transform)

Description copied from interface: XyShape

Transform the shape using the given transform. Due to potential distortion the result may be a different type of shape than this one.

Specified by:

transformedBy in interface XyShape<XyShapeList>

Parameters:

transform - affine transform to apply.

Returns:

transformed result

translatedBy

public XyShapeList<T> translatedBy(double offsetX,
                                   double offsetY)

Description copied from interface: XyShape

Translate the shape by adding all coordinates to the given x and y offsets. The resulting shape must be of the same class as the original.

Specified by:

translatedBy in interface XyShape<XyShapeList>

Parameters:

offsetX - offset for the x dimension

offsetY - offset for the y dimension

Returns:

offset result

iterator

public java.util.Iterator<XyPoint> iterator()

Specified by:

iterator in interface java.lang.Iterable<XyPoint>
