Set

• java.lang.Object
  • Animation

Fields Summary
static final String[]	REQUIRED_TRAITS Required Set traits
String[]	to The target Set value.
RefValues	refValues The RefValues corresponding to this <set> element. A <set> element has a single segment with the same begin and end value.
String	traitQName The trait's qualified name.

Constructors Summary
public Set(DocumentNode ownerDocument) Builds a new Set element that belongs to the given document. This Set will belong to the DocumentNode's time container. param ownerDocument the document this node belongs to. throws IllegalArgumentException if the input ownerDocument is null super(ownerDocument, SVGConstants.SVG_SET_TAG);

Methods Summary
java.lang.Object[]	f(long t) This is the Set element's animation function. It is very simple as it simply returns the 'to' value, no matter what time t is. param t the animation's simple time. return refValues.getSegment(0).getStart();
public java.lang.String[]	getRequiredTraits() return an array of traits that are required by this element. return REQUIRED_TRAITS;
public java.lang.String	getTraitImpl(java.lang.String name) Set supports the to and attributeName traits. Returns the trait value as String. In SVG Tiny only certain traits can be obtained as a String value. Syntax of the returned String matches the syntax of the corresponding attribute. This element is exactly equivalent to {@link org.w3c.dom.svg.SVGElement#getTraitNS getTraitNS} with namespaceURI set to null. The method is meant to be overridden by derived classes. The implementation pattern is that derived classes will override the method and call their super class' implementation. If the ElementNode implementation is called, it means that the trait is either not supported or that it cannot be seen as a String. param name the requested trait name. return the trait value. throws DOMException with error code NOT_SUPPORTED_ERROR if the requested trait is not supported on this element or null. throws DOMException with error code TYPE_MISMATCH_ERR if requested trait's computed value cannot be converted to a String (SVG Tiny only). if (SVGConstants.SVG_TO_ATTRIBUTE == name) { return to[0]; } else if (SVGConstants.SVG_ATTRIBUTE_NAME_ATTRIBUTE == name) { return traitQName; } else { return super.getTraitImpl(name); }
public ElementNode	newInstance(DocumentNode doc) Used by DocumentNode to create a new instance from a prototype TimedElementNode. param doc the DocumentNode for which a new node is should be created. return a new TimedElementNode for the requested document. return new Set(doc);
public void	setTraitImpl(java.lang.String name, java.lang.String value) Set supports the attributeName and to traits. param name the trait's name. param value the trait's value. throws DOMException with error code NOT_SUPPORTED_ERR if the requested trait is not supported on this element or null. throws DOMException with error code TYPE_MISMATCH_ERR if the requested trait's value cannot be specified as a String throws DOMException with error code INVALID_ACCESS_ERR if the input value is an invalid value for the given trait or null. throws DOMException with error code NO_MODIFICATION_ALLOWED_ERR: if attempt is made to change readonly trait. if (SVGConstants.SVG_TO_ATTRIBUTE == name) { checkWriteLoading(name); if (value == null) { throw illegalTraitValue(name, value); } to[0] = value; } else if (SVGConstants.SVG_ATTRIBUTE_NAME_ATTRIBUTE == name) { checkWriteLoading(name); if (value == null) { throw illegalTraitValue(name, value); } // Now, if this is a QName, we need to use the namespace prefix map. int i = value.indexOf(':"); if (i == -1) { this.traitName = value.intern(); this.traitQName = value.intern(); } else { if (i == value.length() - 1) { // ':' is the last character, this is invalid. throw illegalTraitValue(name, value); } String prefix = value.substring(0, i); String tName = value.substring(i+1); String ns = ownerDocument.toNamespace(prefix, this); if (ns == null) { throw illegalTraitValue(name, value); } traitName = tName.intern(); traitNamespace = ns.intern(); traitQName = value; } } else { super.setTraitImpl(name, value); }
boolean	supportsTrait(java.lang.String traitName) Supported traits: to, attributeName param traitName the name of the trait which the element may support. return true if this element supports the given trait in one of the trait accessor methods. if (SVGConstants.SVG_TO_ATTRIBUTE == traitName || SVGConstants.SVG_ATTRIBUTE_NAME_ATTRIBUTE == traitName) { return true; } else { return super.supportsTrait(traitName); }
void	validate() Validating a Set consists in: a) Setting its target element. If there was no idRef, then targetElement is still null and will be positioned to the parent node. b) Validating the to value with the targetElement, using the target trait name, namespace and value. throws DOMException if there is a validation error, for example if the to value is incompatible with the target trait or if the target trait is not animatable. // a) Set the target element. if (targetElement == null) { targetElement = (ElementNode) parent; } // b) Validate the to value with the target element. traitAnim = targetElement.getSafeTraitAnimNS(traitNamespace, traitName); if (to[0] != null) { refValues = traitAnim.toRefValues(this, to, null, SVGConstants.SVG_TO_ATTRIBUTE); } else { hasNoEffect = true; }
