Constructor Detail

IfStatement

public IfStatement(ConditionalOrExpression condition,
                   Statement ifBody)

instantiate an if statement

Parameters:

condition - the condition

ifBody - the statement to execute if the condition is true

IfStatement

public IfStatement(ConditionalOrExpression condition,
                   Statement ifBody,
                   Statement elseBody)

instantiate an if-else statement

Parameters:

condition - the condition

ifBody - the statement to execute if the condition is true

elseBody - the statement to execute if the condition is false

Method Detail

executeLogic

public void executeLogic(Context context)
                  throws LogicException

process this logic code in the specified context

Specified by:

executeLogic in interface LogicCodeExecutable

Parameters:

context - contains the current context of the logic processor

Throws:

TypeMismatchException - thrown if the condition does not evaluate to a literal boolean value

LogicException - thrown if an exception occurs while processing the logic

validateTypes

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

Description copied from interface: LogicCodeExecutable

Attempts to validate the type-correctness of all constituent LogicCodeEvaluatable logic code. An exception is thrown if there is some type-check failure.

Specified by:

validateTypes in interface LogicCodeExecutable

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

Throws:

LogicException - thrown if an exception if an invalid test, test result, or test option is found
