                       PrimaryExpression operand)

instantiate the conditional expression

Parameters:

operator - operator

operand - operand

Method Detail

evaluateLogic

public Literal evaluateLogic(Context context)
                      throws LogicException

evaluate this logic code in the specified context

Specified by:

evaluateLogic in interface LogicCodeEvaluatable

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

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

Description copied from interface: LogicCodeEvaluatable

returns the kind of literal this evaluates to

Specified by:

evaluateTypeOnly in interface LogicCodeEvaluatable

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
