Method Summary

Modifier and TypeMethod and Description
public void
callVisitors(ExpressionOwner owner, XPathVisitor visitor)

Implements com.sun.org.apache.xpath.internal.XPathVisitable.callVisitors.

This will traverse the heararchy, calling the visitor for each member.

public boolean

Returns:

true if traversal outside the context node's subtree can occur.
canTraverseOutsideSubtree()

Overrides com.sun.org.apache.xpath.internal.Expression.canTraverseOutsideSubtree.

Tell if this expression or it's subexpressions can traverse outside the current subtree.

public boolean
deepEquals(Expression expr)

Implements abstract com.sun.org.apache.xpath.internal.Expression.deepEquals.

Compare this object with another object and see if they are equal, include the sub heararchy.

public XObject

Returns:

com.sun.org.apache.xpath.internal.patterns.NodeTest#SCORE_NODETEST, com.sun.org.apache.xpath.internal.patterns.NodeTest#SCORE_NONE, com.sun.org.apache.xpath.internal.patterns.NodeTest#SCORE_NSWILD, com.sun.org.apache.xpath.internal.patterns.NodeTest#SCORE_QNAME, or com.sun.org.apache.xpath.internal.patterns.NodeTest#SCORE_OTHER.
execute(XPathContext
XPath runtime context.
xctxt)

Implements abstract com.sun.org.apache.xpath.internal.Expression.execute.

Test a node to see if it matches any of the patterns in the union.

public void
fixupVariables(List<QName> vars, int globalsSize)

Implements abstract com.sun.org.apache.xpath.internal.Expression.fixupVariables.

No arguments to process, so this does nothing.

public StepPattern[]

Returns:

an array of the contained step patterns to be tested.
getPatterns()

Get the contained step patterns to be tested.

public void
setPatterns(StepPattern[]
the contained step patterns to be tested.
patterns)

Set the contained step patterns to be tested.

public void callVisitors(ExpressionOwner owner, XPathVisitor visitor)

Implements com.sun.org.apache.xpath.internal.XPathVisitable.callVisitors.

Doc from com.sun.org.apache.xpath.internal.XPathVisitable.callVisitors.

This will traverse the heararchy, calling the visitor for each member. If the called visitor method returns false, the subtree should not be called.

public boolean canTraverseOutsideSubtree()

Overrides com.sun.org.apache.xpath.internal.Expression.canTraverseOutsideSubtree.

Returns:boolean

true if traversal outside the context node's subtree can occur.

executeback to summary
public XObject execute(XPathContext xctxt) throws TransformerException

Implements abstract com.sun.org.apache.xpath.internal.Expression.execute.

Test a node to see if it matches any of the patterns in the union.

Parameters
xctxt:XPathContext

XPath runtime context.

Returns:XObject
