AttributeIterator
AttributeIterator(Compiler compiler, int opPos, int analysis) throws TransformerException Create a AttributeIterator object.- Parameters:
compiler
- A reference to the Compiler that contains the op map.opPos
- The position within the op map, which contains the location path expression for this iterator.- Throws:
TransformerException
- if any

Method Details
-
getNextNode
protected int getNextNode()Get the next node via getNextXXX. Bottlenecked for derived class override.- Overrides:
getNextNode
in classChildTestIterator
- Returns:
- The next node on the axis, or DTM.NULL.
-
getAxis
public int getAxis()Returns the axis being iterated, if it is known.- Specified by:
getAxis
in interfaceDTMIterator
- Overrides:
getAxis
in classChildTestIterator
- Returns:
- Axis.CHILD, etc., or -1 if the axis is not known or is of multiple types.
