params
- The ParameterSet passed in by the user, eg. from the command linepublic boolean useGlobalParameter(int fingerprint, GlobalParam binding, XPathContext context) throws XPathException
fingerprint
- The fingerprint of the parameterbinding
- The XSLParam element to bind its value toXPathException
public void defineGlobalVariable(GlobalVariable binding, ValueRepresentation value)
binding
- identifies the variablevalue
- the value of the variablepublic void setExecuting(GlobalVariable binding, boolean executing) throws XPathException
XPathException
- If an attempt is made to set the flag when it is already set, this means
the definition of the variable is circular.public ValueRepresentation getGlobalVariableValue(GlobalVariable binding)
binding
- the Binding that establishes the unique instance of the variablepublic ValueRepresentation getGlobalVariable(int slot)
slot
- the slot number of the required variablepublic void assignGlobalVariable(GlobalVariable binding, ValueRepresentation value)
