java.lang.Object
   net.sf.saxon.xpath.JAXPVariable

JAXPVariable
final public class JAXPVariable implements VariableDeclaration,Binding(Code)
An object representing an XPath variable for use in the JAXP XPath API. The object is created at compile time when the parser tries to bind a variable reference; the value is fetched at run-time from the XPathVariableResolver. With this interface, there is no way of reporting a static error if the variable has not been declared.

In Saxon terms, this class is both a VariableDeclaration and a Binding. Unlike a normal VariableDeclaration, it isn't created in advance, but is created on demand when the parser encounters a variable reference. This actually means that if the XPath expression contains two references to the same variable, two VariableDeclarations will be created; however, they will be indistinguishable to the VariableResolver. Acting as a VariableDeclaration, the object goes through the motions of fixing up a binding to a variable reference (in practice, of course, there is exactly one reference to the variable). Acting as a run-time binding, it then evaluates the variable by calling the XPathVariableResolver supplied by the API caller. If no XPathVariableResolver was supplied, an error is reported when a variable is encountered; but if the variable resolver doesn't recognize the variable name, it returns null, which is treated as an empty sequence.




Constructor Summary
public  JAXPVariable(QNameValue name, XPathVariableResolver resolver)
    

Method Summary
public  ValueRepresentationevaluateVariable(XPathContext context)
     Get the value of the variable.
public  intgetLocalSlotNumber()
     If this is a local variable held on the local stack frame, return the corresponding slot number.
public  intgetNameCode()
     Establish the fingerprint of the name of this variable.
public  StringgetVariableName()
     Get the name of the variable.
final public  booleanisAssignable()
     Test whether it is permitted to assign to the variable using the saxon:assign extension element.
public  booleanisGlobal()
     Indicate whether the binding is local or global.
 QNamemakeQName(QNameValue in)
    
public  voidregisterReference(BindingReference ref)
     Method called by the XPath expression parser to register a reference to this variable.


Constructor Detail
JAXPVariable
public JAXPVariable(QNameValue name, XPathVariableResolver resolver)(Code)
Private constructor: for use only be the protected factory method make()




Method Detail
evaluateVariable
public ValueRepresentation evaluateVariable(XPathContext context) throws XPathException(Code)
Get the value of the variable. This method is used by the XPath execution engine to retrieve the value.
Parameters:
  context - The dynamic evaluation context The value of the variable



getLocalSlotNumber
public int getLocalSlotNumber()(Code)
If this is a local variable held on the local stack frame, return the corresponding slot number. In other cases, return -1.



getNameCode
public int getNameCode()(Code)
Establish the fingerprint of the name of this variable. Dummy implementation, not used. -1, always



getVariableName
public String getVariableName()(Code)
Get the name of the variable. Used for diagnostic purposes only. the name of the variable, as a string (containing the raw QName)



isAssignable
final public boolean isAssignable()(Code)
Test whether it is permitted to assign to the variable using the saxon:assign extension element. This will only be for an XSLT global variable where the extra attribute saxon:assignable="yes" is present.



isGlobal
public boolean isGlobal()(Code)
Indicate whether the binding is local or global. A global binding is one that has a fixed value for the life of a query or transformation; any other binding is local.



makeQName
QName makeQName(QNameValue in)(Code)



registerReference
public void registerReference(BindingReference ref)(Code)
Method called by the XPath expression parser to register a reference to this variable. This method should not be called by users of the API.
