AVT
public AVT(StylesheetHandler handler, String uri, String name, String rawName, String stringedValue, ElemTemplateElement owner) throws TransformerException Construct an AVT by parsing the string, and either constructing a vector of AVTParts, or simply hold on to the string if the AVT is simple.- Parameters:
handler
- non-null reference to StylesheetHandler that is constructing.uri
- non-null reference to URI, "" if null namespace.name
- non-null reference to name string.rawName
- prefixed name.stringedValue
- non-null raw string value.- Throws:
TransformerException

Method Details
-
getRawName
Get the raw name of the attribute, with the prefix unprocessed.- Returns:
- non-null reference to prefixed name.
-
setRawName
Get the raw name of the attribute, with the prefix unprocessed.- Parameters:
rawName
- non-null reference to prefixed name.
-
getName
Get the local name of the attribute.- Returns:
- non-null reference to name string.
-
setName
Set the local name of the attribute.- Parameters:
name
- non-null reference to name string.
-
getURI
Get the namespace URI of the attribute.- Returns:
- non-null reference to URI, "" if null namespace.
-
setURI
Get the namespace URI of the attribute.- Parameters:
uri
- non-null reference to URI, "" if null namespace.
-
getSimpleString
Get the AVT as the original string.- Returns:
- The AVT as the original string
-
evaluate
public String evaluate(XPathContext xctxt, int context, PrefixResolver nsNode) throws TransformerException Evaluate the AVT and return a String.- Parameters:
xctxt
- Te XPathContext to use to evaluate this.context
- The current source tree context.nsNode
- The current namespace context (stylesheet tree context).- Returns:
- The AVT evaluated as a string
- Throws:
TransformerException
-
isContextInsensitive
public boolean isContextInsensitive()Test whether the AVT is insensitive to the context in which it is being evaluated. This is intended to facilitate compilation of templates, by allowing simple AVTs to be converted back into strings. Currently the only case we recognize is simple strings. ADDED 9/5/2000 to support compilation experiment- Returns:
- True if the m_simpleString member of this AVT is not null
-
canTraverseOutsideSubtree
public boolean canTraverseOutsideSubtree()Tell if this expression or it's subexpressions can traverse outside the current subtree.- Returns:
- true if traversal outside the context node's subtree can occur.
-
fixupVariables
This function is used to fixup variables from QNames to stack frame indexes at stylesheet build time.- Parameters:
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).
-
callVisitors
Description copied from interface:XSLTVisitable
This will traverse the heararchy, calling the visitor for each member. If the called visitor method returns false, the subtree should not be called.- Specified by:
callVisitors
in interfaceXSLTVisitable
- Parameters:
visitor
- The visitor whose appropriate method will be called.- See Also:
-
isSimple
public boolean isSimple()Returns true if this AVT is simple
