Method Detail

calcScore
public final void calcScore()
Static calc of match score.- Overrides:
calcScore
in classStepPattern
-
fixupVariables
public 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.- Overrides:
fixupVariables
in classStepPattern
- 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).globalsSize
- The number of variables in the global variable area.

.- Throws:
javax.xml.transform.TransformerException
-
