Constructor Detail

UnaryExpression

public UnaryExpression(int op,
                       AssertionExpression expr,
                       Context context)
                throws AssertionException

Construct a new object.

Parameters:

op - The operator associated with this unary expression.

expr - The expression being paired with the operator.

Throws:

AssertionException - The exception raised if the operator does not fall within the range of supported operators OR if the expression is null.

Method Detail

getOp

public int getOp()

Return the unary operator.

getOpSymbol

public java.lang.String getOpSymbol()

Return the symbol associated with the operator. It is assumed the operator is valid thanks to the check in the constructor.

getExpression

public AssertionExpression getExpression()

Return the expression.

hasPure

public boolean hasPure()

Return TRUE if the expression is PURE clause; otherwise, return FALSE.

Specified by:

hasPure in class AssertionExpression

hasResult

public boolean hasResult()

Return TRUE if the expression contains RESULT; otherwise, return FALSE.

Specified by:

hasResult in class AssertionExpression

hasResultOrArg

public boolean hasResultOrArg()

Return TRUE if a result clause or method argument is found within the expression; otherwise, return FALSE.

Specified by:

hasResultOrArg in class AssertionExpression

hasResultOrOutArg

public boolean hasResultOrOutArg(boolean outOnly)

Return TRUE if a result clause or output argument is found within the expression; otherwise, return FALSE.

Specified by:

hasResultOrOutArg in class AssertionExpression

Parameters:

outOnly - TRUE if only concerned with output arguments that are out only; FALSE otherwise.

hasMethodCall

public boolean hasMethodCall()

Return TRUE if the expression has at least one method call; otherwise, return FALSE. Clearly this expression isn't a method call BUT the expression may be or contain one.

Specified by:

hasMethodCall in class AssertionExpression

getDefaultComplexity

public int getDefaultComplexity()

Return the default complexity of the expression (0 = constant, 1 = linear, etc.).

Specified by:

getDefaultComplexity in class AssertionExpression

hasBuiltinMethod

public boolean hasBuiltinMethod(int type)

Return TRUE if the expression is, or has, the specified built-in method call; otherwise, return FALSE.

Specified by:

hasBuiltinMethod in class AssertionExpression

hasUserDefinedMethod

public boolean hasUserDefinedMethod(boolean any)

Return TRUE if the expression has a method AND the method is any user-defined method (when any is TRUE) or it is an user-defined method with a throws clause (if any is FALSE); otherwise, return FALSE.

Specified by:

hasUserDefinedMethod in class AssertionExpression

requiresExtendableContext

public boolean requiresExtendableContext()

Return TRUE if extendable context is required to validate the expression; otherwise, return FALSE.

Specified by:

requiresExtendableContext in class AssertionExpression

requiresMethodContext

public boolean requiresMethodContext()

Return TRUE if method context is required to validate the expression; otherwise, return FALSE.

Specified by:

requiresMethodContext in class AssertionExpression

validateSemantics

protected void validateSemantics(Extendable ext,
                                 Method m)
                          throws AssertionException

Validate the expression semantics, if necessary, within the context of the extendable and optional method.

Specified by:

validateSemantics in class AssertionExpression

Parameters:

ext - The interface or class that owns this expression.

m - The method that owns this expression.

Throws:

AssertionException - The exception that can be raised during validation.

getArrayIterMacros

public java.util.ArrayList getArrayIterMacros(java.lang.String epvVar,
                                              int[] startInd)

Return the list of array iteration macro messages, if any. Each message is a string where the first character indicates the return type associated with the iteration. The remaining characters will be the actual macro invocation.

Specified by:

getArrayIterMacros in class AssertionExpression

getNumArrayIterMacrosByType

public int getNumArrayIterMacrosByType(char type)

Returns the number of macros supported by this assertion of the specified type. Valid types are given in MethodCall.java.

Specified by:

getNumArrayIterMacrosByType in class AssertionExpression

cExpression

public java.lang.String cExpression(java.lang.String epvVar,
                                    int[] startInd)

Return the C version of the expression.

toString

public java.lang.String toString()

Return the stringified version of the expression (in SIDL form).

Specified by:

accept

public java.lang.Object accept(ExprVisitor ev,
                               java.lang.Object data)

Description copied from class: AssertionExpression

Implement the "visitor pattern".

Specified by:
