Constructor Detail

InstantiateExpression

public InstantiateExpression(VariableDeclaration project,
                             IVersionRestriction restriction,
                             java.lang.String name,
                             CallArgument... arguments)
                      throws VilException

Creates an instantiate expression.

Parameters:

project - the project variable

restriction - optional version restrictions (may be null)

name - the optional name of the rule to be executed (may be null and points then to the main rule)

arguments - the rule call arguments

Throws:

VilException - in case that the expression cannot be resolved

InstantiateExpression

public InstantiateExpression(java.lang.String name,
                             CallArgument... arguments)
                      throws VilException

Creates an instantiate expression.

Parameters:

name - the (qualified) name of the rule to be called

arguments - the rule call arguments

Throws:

VilException - in case that the expression cannot be resolved

Method Detail

getProject

public VariableDeclaration getProject()

Returns the project variable.

Returns:

the project variable (may be null if a name-based call is given)

getVersionRestriction

public IVersionRestriction getVersionRestriction()

Returns the version restriction.

Returns:

the version restriction (may be null if absent)

getOperationClass

protected java.lang.Class<? extends Rule> getOperationClass()

Description copied from class: ModelCallExpression

Returns the actual operation class, i.e., the class of the operation.

Specified by:

getOperationClass in class ModelCallExpression<VariableDeclaration,Script,Rule>

Returns:

the operation class

inferType

public TypeDescriptor<?> inferType()
                            throws VilException

Description copied from class: Expression

Infers the type of this expression including the type of the contained sub-expressions.

Overrides:

inferType in class ModelCallExpression<VariableDeclaration,Script,Rule>

Returns:

the type of this expression

Throws:

VilException - in case that inferring the type fails

accept

public java.lang.Object accept(IExpressionVisitor visitor)
                        throws VilException

Description copied from class: Expression

Visits the expression.

Specified by:

accept in class Expression

Parameters:

visitor - the visitor

Returns:

the result of visiting this expression (may be null)

Throws:

VilException - in case that visiting fails (e.g., execution)

isVisible

public boolean isVisible(Script fromModel)

Description copied from class: ModelCallExpression

Returns whether the resolved model operation is visible.

Specified by:

isVisible in class ModelCallExpression<VariableDeclaration,Script,Rule>

Parameters:

fromModel - the model issuing the call

Returns:

true if the operation is visible, false else
