Class AbstractSVGLength

java.lang.Object
  org.apache.batik.dom.svg.AbstractSVGLength

All Implemented Interfaces:: org.w3c.dom.svg.SVGLength

Direct Known Subclasses:: AbstractSVGAnimatedLength.BaseSVGLength, AbstractSVGLengthList.SVGLengthItem, SVGOMLength

public abstract class AbstractSVGLength
extends java.lang.Object
implements org.w3c.dom.svg.SVGLength

Default implementation for SVGLength. This implementation provides the basic functionalities of SVGLength. To have a complete implementation, an element is required to resolve the units. According to the usage of this AbstractSVGLength, the reset() method is after changes being made to the unitType or the value of this length. Before any values are return to the user of the AbstractSVGLength, the revalidate() method is being called to insure the validity of the value and unit type held by this object.
