Constructor Detail

VariableInitialization

public VariableInitialization(LiteralType type,
                              Identifier iden,
                              Expression exp)

Construct a variable to be initialized

Parameters:

type - the type of variable to initialize

iden - name of the variable to initialize

exp - the value to assign iden

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 - occurs if the declared variable type is different from the initializer's type

RedefinedVariableException - occurs if the specified variable's name has already been declared

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

getType

public LiteralType getType()

gets the type of variable to initialize

getVarName

public java.lang.String getVarName()

gets the name of this variable

getVarValue

public Expression getVarValue()

gets the name and initial value of this variable
