Method Summary

Modifier and Type	Method and Description
java.lang.String	getExpressionOperator(int index)
protected java.lang.Object	getValueBody(OgnlContext context, java.lang.Object source) Subclasses implement this method to do the actual work of extracting the appropriate value from the source object.
protected void	setValueBody(OgnlContext context, java.lang.Object target, java.lang.Object value) Subclasses implement this method to do the actual work of setting the appropriate value in the target object.
java.lang.String	toGetSourceString(OgnlContext context, java.lang.Object target) 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.

Method Detail

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

setValueBody

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

Description copied from class: SimpleNode

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.

Overrides:

setValueBody in class SimpleNode

Throws:

OgnlException

getExpressionOperator

public java.lang.String getExpressionOperator(int index)

Overrides:

getExpressionOperator in class ExpressionNode

toGetSourceString

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

Description copied from interface: JavaSource

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 ExpressionNode

Returns:

Literal java string representation of an object get.
