Constructor Detail

### Step

    public Step(byte axis,
                NodeTest nodeTest)

Method Detail

### addFilter

    public Step addFilter(Expression exp)

### setFilters

    public void setFilters(Expression[] filters,
                           int count)

### getAxis

    public byte getAxis()

### getNodeTest

    public NodeTest getNodeTest()

### getFilters

    public Expression[] getFilters()

### getNumberOfFilters

    public int getNumberOfFilters()

### simplify

    public Step simplify()
                  throws XPathException

  Simplify the step. Return either the same step after simplification, or null, indicating that the step will always give an empty result.

  Throws:
    `XPathException`

### enumerate

    public NodeEnumeration enumerate(NodeInfo node,
                                     Context context)
                              throws XPathException

  Enumerate this step.

  Throws:
    `XPathException`

### display

    public void display(int level)
