protected IResolvedFeatures.Provider getResolvedFeaturesProvider()

Specified by:

getResolvedFeaturesProvider in class AbstractFeatureScopeSession

getTypeScopes

protected TypeScopes getTypeScopes()

Specified by:

getTypeScopes in class AbstractFeatureScopeSession

getConstructorScopes

protected ConstructorScopes getConstructorScopes()

Specified by:

getConstructorScopes in class AbstractFeatureScopeSession

getDefaultScopeProvider

protected org.eclipse.xtext.scoping.IScopeProvider getDefaultScopeProvider()

Specified by:

getDefaultScopeProvider in class AbstractFeatureScopeSession

getLocalElement

public org.eclipse.xtext.resource.IEObjectDescription getLocalElement(org.eclipse.xtext.naming.QualifiedName name)

Description copied from interface: IFeatureScopeSession

Find a local element with the given qualified name.

Returns:

the known element or null.

getLocalElements

public java.util.List<org.eclipse.xtext.resource.IEObjectDescription> getLocalElements()

Description copied from interface: IFeatureScopeSession

Return all local elements that are known in this session.

Specified by:

getLocalElements in interface IFeatureScopeSession

Overrides:

getLocalElements in class AbstractFeatureScopeSession

Returns:

all local elements. Never null.

getId

protected int getId()

Description copied from class: AbstractFeatureScopeSession

A simple means to identify the session.

Specified by:

getId in class AbstractFeatureScopeSession

isInstanceContext

public boolean isInstanceContext()

Returns true if this can be validly resolved in the current scope. By default, a session is not an instance context.

See Also:

IFeatureScopeSession.toInstanceContext()

isConstructorContext

public boolean isConstructorContext()

Returns true if the current expression is used in a constructor body. By default, a session is not a constructor context.

See Also:

IFeatureScopeSession.toConstructorContext()

isVisible

public boolean isVisible(org.eclipse.xtext.common.types.JvmMember member)

Returns true if the member is visible according to the JvmVisibility and the local context. By default, all public features are considered to be accessible.

Parameters:

member - the member that shall be accessed.

Returns:

true if the feature can be accessed.

isVisible

public boolean isVisible(org.eclipse.xtext.common.types.JvmMember member,
                         LightweightTypeReference receiverType,
                         org.eclipse.xtext.common.types.JvmIdentifiableElement receiverFeature)

Returns true if the member is visible according to the JvmVisibility and the local context when invoked on the given receiver feature which resolves to the given type. By default, all public features are considered to be accessible.

Parameters:

member - the member that shall be accessed.

receiverType - the type of the receiver. May be unknown.

receiverFeature - the links the receiver of the feature call to the given member. May be unknown.

Returns:

true if the feature can be accessed.
