Method Detail

jjtOpen

public void jjtOpen()

Description copied from interface: Node

This method is called after the node has been made the current node. It indicates that child nodes can now be added to it.

Specified by:

jjtOpen in interface Node

---

jjtClose

public void jjtClose()

Description copied from interface: Node

This method is called after all the child nodes have been added.

Specified by:

jjtClose in interface Node

---

jjtSetParent

public void jjtSetParent(Node n)

Description copied from interface: Node

This pair of methods are used to inform the node of its parent.

Specified by:

jjtSetParent in interface Node

---

jjtGetParent

public Node jjtGetParent()

Specified by:

jjtGetParent in interface Node

---

jjtAddChild

public void jjtAddChild(Node n,
                        int i)

Description copied from interface: Node

This method tells the node to add its argument to the node's list of children.

Specified by:

jjtAddChild in interface Node

---

jjtGetChild

public Node jjtGetChild(int i)

Description copied from interface: Node

This method returns a child node. The children are numbered from zero, left to right.

Specified by:

jjtGetChild in interface Node

---

jjtGetNumChildren

public int jjtGetNumChildren()

Description copied from interface: Node

Return the number of children the node has.

Specified by:

jjtGetNumChildren in interface Node

---

toString

public java.lang.String toString()

Description copied from class: java.lang.Object

Convert this Object to a human-readable String. There are no limits placed on how long this String should be or what it should contain. We suggest you make it as intuitive as possible to be able to place it into System.out.println() 55 and such.

It is typical, but not required, to ensure that this method never completes abruptly with a java.lang.RuntimeException.

This method will be called when performing string concatenation with this object. If the result is null, string concatenation will instead use "null".

The default implementation returns getClass().getName() + "@" + Integer.toHexString(hashCode()).

---

toString

public java.lang.String toString(java.lang.String prefix)

---

dump

public void dump(java.io.PrintWriter writer,
                 java.lang.String prefix)

---

getIndexInParent

public int getIndexInParent()

---

getNextSibling

public Node getNextSibling()

---

getDepthString

private static java.lang.String getDepthString(int depth)

---

evaluateGetValueBody

protected java.lang.Object evaluateGetValueBody(OgnlContext context,

                                    java.lang.Object value)
                             throws OgnlException

Extracts the value from the given source object that is appropriate for this node within the given context.

Specified by:

getValue in interface Node

---

getValueBody

protected abstract java.lang.Object getValueBody(OgnlContext context,

                                          throws OgnlException

Subclasses implement this method to do the actual work of extracting the appropriate value from the source object.

---

setValue

public final void setValue(OgnlContext context,
                           java.lang.Object target,
                           java.lang.Object value)
                    throws OgnlException

Description copied from interface: Node

Sets the given value in the given target as appropriate for this node within the given context.

Specified by:

setValue in interface Node

---

setValueBody

protected void setValueBody(OgnlContext context,
                            java.lang.Object target,
                            java.lang.Object value)
                     throws OgnlException

Subclasses implement this method to do the actual work of setting the appropriate value in the target object. The default implementation throws an InappropriateExpressionException, meaning that it cannot be a set expression.

---

isNodeConstant

public boolean isNodeConstant(OgnlContext context)
                       throws OgnlException

Returns true iff this node is constant without respect to the children.
