Package org.apache.xpath.axes

Class OneStepIteratorForward

    • Constructor Detail

      • OneStepIteratorForward

        public OneStepIteratorForward​(int axis)
        Create a OneStepIterator object that will just traverse the self axes.
        Parameters:
        axis - One of the org.apache.xml.dtm.Axis integers.
        Throws:
        javax.xml.transform.TransformerException

    • Method Detail

      • setRoot

        public void setRoot​(int context,
                    java.lang.Object environment)
        Initialize the context values for this expression after it is cloned.
        Specified by:
        setRoot in interface DTMIterator
        Overrides:
        setRoot in class ChildTestIterator
        Parameters:
        context - The XPath runtime context for this transformation.
        environment - The environment object. The environment in which this iterator operates, which should provide:
        • a node (the context node... same value as "root" defined below)
        • a pair of non-zero positive integers (the context position and the context size)
        • a set of variable bindings
        • a function library
        • the set of namespace declarations in scope for the expression.

            • At this time the exact implementation of this environment is application dependent. Probably a proper interface will be created fairly soon.

      • getAxis

        public int getAxis()
        Returns the axis being iterated, if it is known.
        Specified by:
        getAxis in interface DTMIterator
        Overrides:
        getAxis in class ChildTestIterator
        Returns:
        Axis.CHILD, etc., or -1 if the axis is not known or is of multiple types.

      • deepEquals

        public boolean deepEquals​(Expression expr)
        Description copied from class: Expression
        Compare this object with another object and see if they are equal, include the sub heararchy.
        Overrides:
        deepEquals in class PredicatedNodeTest
        Parameters:
        expr - Another expression object.
        Returns:
        true if this objects class and the expr object's class are the same, and the data contained within both objects are considered equal.
