Description copied from interface: Node

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

Specified by:

jjtClose in interface Node

Overrides:

jjtClose in class SimpleNode

getValueBody

protected java.lang.Object getValueBody(OgnlContext context,
                                        java.lang.Object source)
                                 throws OgnlException

Description copied from class: SimpleNode

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

Specified by:

getValueBody in class SimpleNode

Throws:

OgnlException

getExpressionOperator

public java.lang.String getExpressionOperator(int index)

Overrides:

getExpressionOperator in class ExpressionNode

isWider

boolean isWider(NodeType type,
                NodeType lastType)

toGetSourceString

public java.lang.String toGetSourceString(OgnlContext context,
                                          java.lang.Object target)

Description copied from class: NumericExpression

Expected to return a java source representation of itself such that it could be turned into a literal java expression to be compiled and executed for ExpressionAccessor.get(OgnlContext, Object) calls.

Specified by:

toGetSourceString in interface JavaSource

Overrides:

toGetSourceString in class NumericExpression

Returns:

Literal java string representation of an object get.

accept

public <R,P> R accept(NodeVisitor<? extends R,? super P> visitor,

Description copied from interface: Node

Supports the Visitor pattern. The method which corresponds to the runtime type of this Node will be called.

Type Parameters:

R - The return type of the visitor.visit method.

P - The type of the second parameter type.

Parameters:

visitor - The visitor to accept.

data - The second parameter to pass through to visitor.visit

Returns:
