getValueBody

protected Object getValueBody(OgnlContext context,
                  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

Parameters:

context - the OgnlContext within which to perform the operation.

source - the Object from which to get the value body.

Returns:

the value body from the source (as appropriate within the provided context).

Throws:

OgnlException - if the value body get fails.

getExpressionOperator

public String getExpressionOperator(int index)
