| NodeTest | | public NodeTest(int whatToShow, String namespace, String name)(Code) | | Construct an NodeTest that tests for namespaces and node names.
Parameters:
whatToShow - Bit set defined mainly by org.w3c.dom.traversal.NodeFilter.
Parameters:
namespace - The namespace to be tested.
Parameters:
name - The local name to be tested. |
| NodeTest | | public NodeTest()(Code) | | Null argument constructor.
|
| calcScore | | protected void calcScore()(Code) | | Static calc of match score.
|
| debugWhatToShow | | public static void debugWhatToShow(int whatToShow)(Code) | | Do a diagnostics dump of a whatToShow bit set.
Parameters:
whatToShow - Bit set defined mainly by org.apache.xml.dtm.DTMFilter. |
| fixupVariables | | public void fixupVariables(java.util.Vector vars, int globalsSize)(Code) | | Node tests by themselves do not need to fix up variables.
|
| getDefaultScore | | public double getDefaultScore()(Code) | | Get the score that this test will return if a test succeeds.
the score that this test will return if a test succeeds. |
| getLocalName | | public String getLocalName()(Code) | | Return the local name to be tested.
the local name to be tested, or NodeTest.WILD, or an empty string. |
| getNamespace | | public String getNamespace()(Code) | | Return the namespace to be tested.
The namespace to be tested for, or NodeTest.WILD, or null. |
| getNodeTypeTest | | public static int getNodeTypeTest(int whatToShow)(Code) | | Tell what node type to test, if not DTMFilter.SHOW_ALL.
Parameters:
whatToShow - Bit set defined mainly by org.apache.xml.dtm.DTMFilter. the node type for the whatToShow. Since whatToShow can specify multiple types, it will return the first bit tested that is on, so the caller of this function should take care that this is the function they really want to call. If none of the known bitsare set, this function will return zero. |
| getStaticScore | | public XNumber getStaticScore()(Code) | | Get the static score for this node test.
Should be one of the SCORE_XXX constants. |
| initNodeTest | | public void initNodeTest(int whatToShow)(Code) | | Initialize this node test by setting the whatToShow property, and
calculating the score that this test will return if a test succeeds.
Parameters:
whatToShow - Bit set defined mainly by org.w3c.dom.traversal.NodeFilter. |
| initNodeTest | | public void initNodeTest(int whatToShow, String namespace, String name)(Code) | | Initialize this node test by setting the whatToShow property and the
namespace and local name, and
calculating the score that this test will return if a test succeeds.
Parameters:
whatToShow - Bit set defined mainly by org.w3c.dom.traversal.NodeFilter.
Parameters:
namespace - The namespace to be tested.
Parameters:
name - The local name to be tested. |
| setLocalName | | public void setLocalName(String name)(Code) | | Set the local name to be tested.
Parameters:
name - the local name to be tested, or NodeTest.WILD, or an empty string. |
| setNamespace | | public void setNamespace(String ns)(Code) | | Set the namespace to be tested.
Parameters:
ns - The namespace to be tested for, or NodeTest.WILD, or null. |
