Methods Summary
public final java.lang.String	getBaseLocalName() Method getBaseLocalName return the XPATH2 tag return XPath2FilterContainer._TAG_XPATH2;
public final java.lang.String	getBaseNamespace() Method getBaseNamespace return XPATH2 tag namespace return XPath2FilterContainer.XPathFilter2NS;
public java.lang.String	getXPathFilterStr() Returns the XPath 2 Filter String return the XPath 2 Filter String return this.getTextFromTextChild();
public org.w3c.dom.Node	getXPathFilterTextNode() Returns the first Text node which contains information from the XPath 2 Filter String. We must use this stupid hook to enable the here() function to work. $todo$ I dunno whether this crashes: here()/ds:Signature[1] return the first Text node which contains information from the XPath 2 Filter String NodeList children = this._constructionElement.getChildNodes(); int length = children.getLength(); for (int i = 0; i < length; i++) { if (children.item(i).getNodeType() == Node.TEXT_NODE) { return children.item(i); } } return null;
public boolean	isIntersect() Returns true if the Filter attribute has value "intersect". return true if the Filter attribute has value "intersect". return this._constructionElement .getAttributeNS(null, XPath2FilterContainer._ATT_FILTER) .equals(XPath2FilterContainer._ATT_FILTER_VALUE_INTERSECT);
public boolean	isSubtract() Returns true if the Filter attribute has value "subtract". return true if the Filter attribute has value "subtract". return this._constructionElement .getAttributeNS(null, XPath2FilterContainer._ATT_FILTER) .equals(XPath2FilterContainer._ATT_FILTER_VALUE_SUBTRACT);
public boolean	isUnion() Returns true if the Filter attribute has value "union". return true if the Filter attribute has value "union". return this._constructionElement .getAttributeNS(null, XPath2FilterContainer._ATT_FILTER) .equals(XPath2FilterContainer._ATT_FILTER_VALUE_UNION);
