Class DefaultDeclarativeQualifiedNameProvider

java.lang.Object

org.eclipse.xtext.naming.IQualifiedNameProvider.AbstractImpl

org.eclipse.xtext.naming.DefaultDeclarativeQualifiedNameProvider

All Implemented Interfaces:

java.util.function.Function<org.eclipse.emf.ecore.EObject,QualifiedName>, IQualifiedNameProvider

public class DefaultDeclarativeQualifiedNameProvider
extends IQualifiedNameProvider.AbstractImpl

Computes the fully qualified name of an EObject by first invoking a method
QualifiedName qualifiedName(MyType ele)
reflectively. And if no such method is found looks up a property 'name' and invokes the value and appends it to the eContainer's qualifiedName. The default implementation performs extensive caching by means of a SimpleCache. Under some circumstances, this may downgrade the performance. Clients may want to override computeFullyQualifiedName(EObject) or getOrComputeFullyQualifiedName(EObject).

Method Detail

getResolver

protected com.google.common.base.Function<org.eclipse.emf.ecore.EObject,java.lang.String> getResolver()

getFullyQualifiedName

public QualifiedName getFullyQualifiedName(org.eclipse.emf.ecore.EObject obj)

Returns:

the qualified name for the given object, null if this IQualifiedNameProvider is not responsible or if the given object doesn't have qualified name.

getOrComputeFullyQualifiedName

protected QualifiedName getOrComputeFullyQualifiedName(org.eclipse.emf.ecore.EObject obj)

Tries to obtain the FQN of the given object from the cache. If it is absent, it computes a new name.

Since:

2.15

See Also:

computeFullyQualifiedName(EObject)

qualifiedName

protected QualifiedName qualifiedName(java.lang.Object ele)

Default for qualifiedName dispatcher. Write a method with this signature but custom Type for dispatching other types.

Since:

2.3

getConverter

protected IQualifiedNameConverter getConverter()

Returns the IQualifiedNameConverter that is used to convert a string which was read from a model to an instance of QualifiedName.

computeFullyQualifiedName

protected QualifiedName computeFullyQualifiedName(org.eclipse.emf.ecore.EObject obj)

Computes the fully qualified name for the given object, if any. Uses the reflective PolymorphicDispatcher on the method name qualifiedName(Object). If there is no such reflective name found, it tries to read an EAttribute name from the given object and appends that to its containers qualified name.

Since:

2.15

See Also:

computeFullyQualifiedNameFromNameAttribute(EObject)

computeFullyQualifiedNameFromNameAttribute

protected QualifiedName computeFullyQualifiedNameFromNameAttribute(org.eclipse.emf.ecore.EObject obj)

Tries to read an EAttribute name from the given object and appends that to its container's qualified name.

Since:

2.15
