net.ssehub.easy.instantiation.core.model.expressions.VarModelIdentifierExpression

public class VarModelIdentifierExpression
extends Expression

Represents an identifier in a variability model. This expression does not need to carry resolved information as it will be resolved at runtime. It can carry an optional type to enable type-safe resolution of expresions.

Constructor Detail

VarModelIdentifierExpression

public VarModelIdentifierExpression(java.lang.String identifier,
                                    TypeDescriptor<?> type,
                                    IModel model)

Creates the representing instance.

Parameters:

identifier - the identifier from VIL

type - the related type (may be null if unknown/unresolved, then IvmlElement is assumed)

model - the model this expression was created for (for further resolution, may be null)

VarModelIdentifierExpression

public VarModelIdentifierExpression(java.lang.String identifier,
                                    TypeDescriptor<?> type,
                                    ITypedModel model)

Creates the representing instance.

Parameters:

identifier - the identifier from VIL

type - the related type (may be null if unknown/unresolved, then IvmlElement is assumed)

model - the model this expression was created for (for further resolution, may be null)

Method Detail

getModel

public ITypedModel getModel()

Returns the model.

Returns:

the model, may be null

getIdentifier

public java.lang.String getIdentifier()

Returns the original identifier.

Returns:

the original identifier

getType

public TypeDescriptor<?> getType()

Returns the related type (without potential exception).

Returns:

the type of the represented variability model element (may be IvmlElement if unknown/unresolved)

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.

Specified by:

inferType in class Expression

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)

markAsResolved

public void markAsResolved()

Marks this identifier expression as resolved and not needed anymore!

isMarkedAsResolved

public boolean isMarkedAsResolved()

Returns whether markAsResolved() was called on this instance.

Returns:

true if resolved, false else
