  • TraitAnim

Fields Summary

Constructors Summary
public FloatTraitAnim(ElementNode targetElement, String traitName, String traitType) Constructs a new FloatTraitAnim for a given ElementNode trait. param targetElement the ElementNode whose trait is animated. param targetTrait the name of the animated trait. param traitType the trait type. super(targetElement, ElementNode.NULL_NS, traitName, traitType);

Methods Summary
void	apply() Applies the animation effect. The implementation makes sure it implements the sandwich model by 'pulling' values from the root animation (i.e., the animation with the highest priority). float[][] v = (float[][]) rootAnim.compute(); targetElement.setFloatArrayTrait(traitName, v);
public java.lang.Object[]	getBaseValue() Returns the BaseValue as an array of objects. return the base value as an object array. The dimensions of the returned array depend on the trait. see com.sun.perseus.model.BaseValue return targetElement.validateFloatArrayTrait( traitName, getSpecifiedTraitNS(), targetElement.getNamespaceURI(), targetElement.getLocalName(), traitNamespace, traitName);
protected java.lang.String	getTraitImpl() return the trait's value, as a String. // This returns the computed trait value, using the specified // trait value. float[][] v = targetElement.validateFloatArrayTrait( traitName, specifiedTraitValue, targetElement.getNamespaceURI(), targetElement.getLocalName(), traitNamespace, traitName); // Now, convert that value to a string. return targetElement.toStringTrait(traitName, v);
public java.lang.Object[]	multiply(java.lang.Object[] value, int iter) Used to multiply an animated trait value by a number of iterations. param value the animated trait value to multiply. param iter the number of iteration to account for. return the multiply result. float[][] fv = (float[][]) value; float[][] r = new float[fv.length][]; for (int ci = 0; ci < fv.length; ci++) { r[ci] = new float[fv[ci].length]; for (int di = 0; di < fv[ci].length; di++) { r[ci][di] = fv[ci][di] * iter; } } return r;
void	setTraitImpl(java.lang.String value) Sets the trait's base value, as a String. param value the new trait base value. throws DOMException with error code INVALID_ACCESS_ERR if the input value is an invalid value for the given trait or null. targetElement.validateFloatArrayTrait(traitName, value, targetElement.getNamespaceURI(), targetElement.getLocalName(), traitNamespace, traitName); specifiedTraitValue = value;
public java.lang.Object[]	sum(java.lang.Object[] valueA, java.lang.Object[] valueB) Used to sum two animated trait values. param valueA the base value. May be null. param valueB the value to add to the base value. If the baseValue if (valueA == null) { return valueB; } float[][] fva = (float[][]) valueA; float[][] fvb = (float[][]) valueB; for (int ci = 0; ci < fva.length; ci++) { for (int di = 0; di < fva[ci].length; di++) { fvb[ci][di] += fva[ci][di]; } } return valueB;
boolean	supportsInterpolation() return true, because FloatTraitAnim support interpolation. return true;
RefValues	toRefValues(Animation anim, java.lang.String[] values, java.lang.String reqTraitNamespace, java.lang.String reqTraitName) Converts the input values set to a RefValues object. param anim the Animation for which the values should be converted. param values a semi-colon seperated list of values which need to be validated. param reqTraitNamespace the namespace of the trait which has the values value on the requesting element. param reqTraitName the name of the trait which has the values value on the requesting element. throws DOMException with error code INVALID_ACCESS_ERR if the input value is incompatible with the given trait. throws NullPointerException if values is null. FloatRefValues refValues = new FloatRefValues(); if (values.length < 1) { throw new IllegalArgumentException(); } if (values.length == 1) { String[] tmpValues = new String[2]; tmpValues[0] = values[0]; tmpValues[1] = values[0]; values = tmpValues; } int nSegments = values.length - 1; refValues.segments = new FloatSegment[nSegments]; // Build the first segment. refValues.segments[0] = new FloatSegment(); refValues.segments[0].start = targetElement.validateFloatArrayTrait(anim.traitName, values[0], anim.getNamespaceURI(), anim.getLocalName(), reqTraitNamespace, reqTraitName); refValues.segments[0].end = targetElement.validateFloatArrayTrait(anim.traitName, values[1], anim.getNamespaceURI(), anim.getLocalName(), reqTraitNamespace, reqTraitName); FloatSegment prevSegment = refValues.segments[0]; for (int i = 1; i < nSegments; i++) { refValues.segments[i] = new FloatSegment(); refValues.segments[i].start = prevSegment.end; refValues.segments[i].end = targetElement.validateFloatArrayTrait(anim.traitName, values[i + 1], anim.getNamespaceURI(), anim.getLocalName(), reqTraitNamespace, reqTraitName); prevSegment = refValues.segments[i]; } return refValues;
