Class CustomOperation

java.lang.Object

net.ssehub.easy.varModel.model.datatypes.Operation

net.ssehub.easy.varModel.model.datatypes.CustomOperation

Direct Known Subclasses:

CustomDynamicOperation

public class CustomOperation
extends Operation

Represents a custom operation as defined in the IVML model. Not that currently custom operations are not generic and that the operand needs to be the holder of the custom operation, i.e. the project in order to support empty parameter lists.

CustomOperation

CustomOperation()

Constructor for serialization.

CustomOperation

public CustomOperation(IDatatype returns,
                       java.lang.String methodname,
                       IDatatype operand,
                       ConstraintSyntaxTree function,
                       DecisionVariableDeclaration[] parameters)

Operation Constructor.

Parameters:

returns - result type of the operation

methodname - name of the operation

operand - the data type the operation is defined for (shall be a project)

function - the operation calculated by this operation

parameters - list of parameters for operation

Method Detail

setFunction

public void setFunction(ConstraintSyntaxTree function)
                 throws CSTSemanticException

Changes the function determining the implementation of this custom operation. function may refer to the parameters of this custom operation.

Parameters:

function - the new function

Throws:

CSTSemanticException - in case that the return type does not comply to the function

getParameterTypes

private static IDatatype[] getParameterTypes(DecisionVariableDeclaration[] decl)

Returns the datatypes of the parameter declarations.

Parameters:

decl - the parameter declarations (may be null)

Returns:

the datatypes (null if decl is null)

getFunction

public ConstraintSyntaxTree getFunction()

Description copied from class: Operation

Returns the function expression calculated by this operation.

Overrides:

getFunction in class Operation

Returns:

the function operation (always null)

getParameterDeclaration

public DecisionVariableDeclaration getParameterDeclaration(int index)

Description copied from class: Operation

Returns the parameter at position index.

Overrides:

getParameterDeclaration in class Operation

Parameters:

index - a 0-based index denoting the parameter to be returned

Returns:

the specified parameter (may be null if there is no formal declaration

getParameter

public DecisionVariableDeclaration getParameter(java.lang.String name)

Description copied from class: Operation

Returns the specified named parameter.

Overrides:

getParameter in class Operation

Parameters:

name - the name of the parameter

Returns:

the named parameter declaration (may be null)

getParameterCount

registerAsOperation

protected boolean registerAsOperation()

Description copied from class: Operation

Returns whether this operation shall be registered as a global operation.

Overrides:

registerAsOperation in class Operation

Returns:

true if it should be registered, false else
