public interface LogicCodeEvaluatable
extends LogicCode

Defines the framework for evaluating code into a literal value. It can be evaluated to a Literal type at compile-time and a Literal value at run-time.

Author:

David Underhill

Method Summary

Literal	evaluateLogic(Context context) evaluate this logic code in the specified context
LiteralType	evaluateTypeOnly(java.util.HashMap<java.lang.String,LiteralType> varTypes, java.util.HashMap<java.lang.String,TestData> testsInfo) returns the kind of literal this evaluates to

Method Detail

evaluateLogic

Literal evaluateLogic(Context context)
                      throws LogicException

evaluate this logic code in the specified context

Parameters:

context - contains the current context of the logic processor

Returns:

the value this logic evaluates to

Throws:

LogicException - thrown if an exception occurs while processing the logic

evaluateTypeOnly

LiteralType evaluateTypeOnly(java.util.HashMap<java.lang.String,LiteralType> varTypes,
                             java.util.HashMap<java.lang.String,TestData> testsInfo)
                             throws LogicException

returns the kind of literal this evaluates to

Parameters:

varTypes - contains the type of value stored by each variable (variables names are keys)

testsInfo - information about each test item keyed on test item names this logic may hold

Returns:

the LiteralType this evaluates to

Throws:

LogicException - thrown if there is a problem with type which prevents this from being evaluated
