Constructor Detail

SuspiciouslyOverloadedCandidate

protected SuspiciouslyOverloadedCandidate(FeatureLinkingCandidate chosenCandidate,
                                          FeatureLinkingCandidate rejectedCandidate)

Method Detail

getChosenCandidate

public FeatureLinkingCandidate getChosenCandidate()

Specified by:

getChosenCandidate in interface ISuspiciouslyOverloadedCandidate

Returns:

the applied candidate.

getRejectedCandidate

public FeatureLinkingCandidate getRejectedCandidate()

Specified by:

getRejectedCandidate in interface ISuspiciouslyOverloadedCandidate

Returns:

the suspiciously rejected candidate.

getPreferredCandidate

public ILinkingCandidate getPreferredCandidate(ILinkingCandidate other)

Description copied from interface: ILinkingCandidate

Produces the best candidate for the current two candidates. It may turn out that both candidates (this and other) are ambiguous so no prefered candidate can be chosen. In that case, a new linking candidate may be produced that carries this information and will use that on ILinkingCandidate.applyToComputationState(), ILinkingCandidate.applyToModel(IResolvedTypes), and IApplicableCandidate.validate(IAcceptor).

Specified by:

getPreferredCandidate in interface ILinkingCandidate

compareTo

protected CandidateCompareResult compareTo(AbstractPendingLinkingCandidate<?> right)

applyToComputationState

public void applyToComputationState()

Description copied from interface: ILinkingCandidate

Apply this candidate to the current computation state model. This propagates the type information about arguments and child expressions to the currently active resolution state.

Specified by:

applyToComputationState in interface ILinkingCandidate

applyToModel

public void applyToModel(IResolvedTypes resolvedTypes)

Description copied from interface: ILinkingCandidate

Injects the resolved feature into the model with the same semantics as the implicit resolve of EMF. This implies that the linked feature call may still point to a proxy afterwards.

Specified by:

applyToModel in interface IApplicableCandidate

Specified by:

applyToModel in interface ILinkingCandidate

validate

public boolean validate(org.eclipse.xtext.util.IAcceptor<? super org.eclipse.xtext.diagnostics.AbstractDiagnostic> result)

Description copied from interface: IApplicableCandidate

Produce diagnostics for this condidate. It is not the responsibility of this candidate to propagate the acceptor to its children.

Specified by:

validate in interface IApplicableCandidate

Returns:

true if further validation should be performed.

appendCandidate

protected void appendCandidate(FeatureLinkingCandidate candidate,
                               java.lang.StringBuilder result)

getFeatureTypeName

protected java.lang.String getFeatureTypeName()

getDeclaratorSimpleName

protected java.lang.String getDeclaratorSimpleName(org.eclipse.xtext.common.types.JvmIdentifiableElement element)

getFeature

public org.eclipse.xtext.common.types.JvmIdentifiableElement getFeature()

Description copied from interface: ILinkingCandidate

The currently considered feature (if any). Otherwise null.

Specified by:

getFeature in interface ILinkingCandidate

getExpression

public XExpression getExpression()

Description copied from interface: ILinkingCandidate

The current expression that shall be linked.

Specified by:

getExpression in interface ILinkingCandidate

getTypeArguments

public java.util.List<LightweightTypeReference> getTypeArguments()

Description copied from interface: ILinkingCandidate

The resolved type arguments.

Specified by:

getTypeArguments in interface ILinkingCandidate

getFeatureCall

public XAbstractFeatureCall getFeatureCall()

Description copied from interface: IFeatureLinkingCandidate

Returns the feature call that is linked.

Specified by:

getFeatureCall in interface IFeatureLinkingCandidate

Returns:

the feature call.

isStatic

public boolean isStatic()

Description copied from interface: IFeatureLinkingCandidate

Returns true if the linked feature is static.

Specified by:

isStatic in interface IFeatureLinkingCandidate

Returns:

whether the feature is static.

isExtension

public boolean isExtension()

Description copied from interface: IFeatureLinkingCandidate

Returns true if the linked feature is contributed by an extension.

Specified by:

isExtension in interface IFeatureLinkingCandidate

Returns:

whether the feature is extension.

isTypeLiteral

public boolean isTypeLiteral()

Description copied from interface: IFeatureLinkingCandidate

Returns true if the feature call is linked as a type literal.

Specified by:

isTypeLiteral in interface IFeatureLinkingCandidate

Returns:

whether the feature call is a type literal rather than a real feature call.
