org.apache.xalan.templates.AVTPart
- java.io.Serializable, XSLTVisitable
public abstract class AVTPart
extends java.lang.Object
Class to hold a part, either a string or XPath,
of an Attribute Value Template.
AVTPart
public AVTPart()
Construct a part.
canTraverseOutsideSubtree
public boolean canTraverseOutsideSubtree()
Tell if this expression or it's subexpressions can traverse outside
the current subtree.
- true if traversal outside the context node's subtree can occur.
evaluate
public abstract void evaluate(XPathContext xctxt,
FastStringBuffer buf,
int context,
PrefixResolver nsNode)
throws javax.xml.transform.TransformerException
Write the evaluated value into the given
string buffer.
xctxt
- The XPath context to use to evaluate this AVT.buf
- Buffer to write into.context
- The current source tree context.nsNode
- The current namespace context (stylesheet tree context).
fixupVariables
public abstract void fixupVariables(java.util.Vector vars,
int globalsSize)
This function is used to fixup variables from QNames to stack frame
indexes at stylesheet build time.
vars
- List of QNames that correspond to variables. This list
should be searched backwards for the first qualified name that
corresponds to the variable reference qname. The position of the
QName in the vector from the start of the vector will be its position
in the stack frame (but variables above the globalsTop value will need
to be offset to the current stack frame).
getSimpleString
public abstract String getSimpleString()
Get the AVT part as the original string.
- the AVT part as the original string.
setXPathSupport
public void setXPathSupport(XPathContext support)
Set the XPath support.
support
- XPathContext to set.
