Constructor Detail

SVGOMAnimatedPathData

public SVGOMAnimatedPathData(AbstractElement elt,
                             String ns,
                             String ln,
                             String defaultValue)
Creates a new SVGOMAnimatedPathData.

Parameters:
elt - The associated element.
ns - The attribute's namespace URI.
ln - The attribute's local name.
defaultValue - The default value if the attribute is not specified.
Method Detail

getAnimatedNormalizedPathSegList

public org.w3c.dom.svg.SVGPathSegList getAnimatedNormalizedPathSegList()
DOM: Implements SVGAnimatedPathData.getAnimatedNormalizedPathSegList().

Specified by:
getAnimatedNormalizedPathSegList in interface org.w3c.dom.svg.SVGAnimatedPathData

getAnimatedPathSegList

public org.w3c.dom.svg.SVGPathSegList getAnimatedPathSegList()
DOM: Implements SVGAnimatedPathData.getAnimatedPathSegList().

Specified by:
getAnimatedPathSegList in interface org.w3c.dom.svg.SVGAnimatedPathData

getNormalizedPathSegList

public org.w3c.dom.svg.SVGPathSegList getNormalizedPathSegList()
DOM: Implements SVGAnimatedPathData.getNormalizedPathSegList().

Returns the SVGPathSegList mapping the normalized static 'd' attribute of the element.

A normalized path is composed only of absolute moveto, lineto and cubicto path segments (M, L and C). Using this subset, the path description can be represented with fewer segment types. Be aware that the normalized 'd' attribute will be a larger String that the original.

Relative values are transformed into absolute, quadratic curves are promoted to cubic curves, and arcs are converted into one or more cubic curves (one per quadrant).

Modifications to the normalized SVGPathSegList will result in substituting the original path with a set of normalized path segments.

Specified by:
getNormalizedPathSegList in interface org.w3c.dom.svg.SVGAnimatedPathData
Returns:
a path segment list containing the normalized version of the path.

getPathSegList

public org.w3c.dom.svg.SVGPathSegList getPathSegList()
DOM: Implements SVGAnimatedPathData.getPathSegList().

Specified by:
getPathSegList in interface org.w3c.dom.svg.SVGAnimatedPathData

check

public void check()
Throws an exception if the path data is malformed.

getUnderlyingValue

public AnimatableValue getUnderlyingValue(AnimationTarget target)
Returns the base value of the attribute as an AnimatableValue.

Specified by:

updateAnimatedValue

protected void updateAnimatedValue(AnimatableValue val)
Updates the animated value with the given AnimatableValue.

Specified by:
updateAnimatedValue in class AbstractSVGAnimatedValue

attrAdded

public void attrAdded(Attr node,
                      String newv)
Called when an Attr node has been added.

Specified by:

attrModified

public void attrModified(Attr node,
                         String oldv,

attrRemoved

public void attrRemoved(Attr node,
                        String oldv)
Called when an Attr node has been removed.

Specified by:
attrRemoved in interface LiveAttributeValue
