Method Details

findLambdaSuperType

public TypeBinding findLambdaSuperType(LambdaExpression lambdaExpression)

closing

protected void closing(Object info)
                throws JavaModelException

Description copied from class: SourceRefElement

This element is being closed. Do any necessary cleanup.

Overrides:

closing in class SourceType

Throws:

JavaModelException

equals

public boolean equals(Object o)

Description copied from class: JavaElement

Returns true if this handle represents the same Java element as the given handle. By default, two handles represent the same element if they are identical or if they represent the same type of element, have equal names, parents, and occurrence counts.

If a subclass has other requirements for equality, this method must be overridden.

Overrides:

equals in class SourceType

See Also:

• Object.equals(java.lang.Object)

calculateHashCode

protected int calculateHashCode()

Overrides:

calculateHashCode in class SourceRefElement

getElementInfo

public SourceTypeElementInfo getElementInfo(org.eclipse.core.runtime.IProgressMonitor monitor)
                                     throws JavaModelException

Description copied from class: JavaElement

Returns the info for this handle. If this element is not already open, it and all of its parents are opened. Does not return null. NOTE: BinaryType infos are NOT rooted under JavaElementInfo.

Overrides:

getElementInfo in class JavaElement

Throws:

JavaModelException - if the element is not present or not accessible

getHandleMementoDelimiter

protected char getHandleMementoDelimiter()

Description copied from class: JavaElement

Returns the char that marks the start of this handles contribution to a memento.

Overrides:

getHandleMementoDelimiter in class Member

See Also:

• JavaElement.getHandleMemento()

getHandleMemento

protected void getHandleMemento(StringBuilder buff)

Overrides:

getHandleMemento in class SourceRefElement

getHandleMemento

protected void getHandleMemento(StringBuilder buff,
 boolean serializeParent,
 boolean serializeChild)

getHandleFromMemento

public IJavaElement getHandleFromMemento(String token,
 MementoTokenizer memento,
 WorkingCopyOwner workingCopyOwner)

Overrides:

getHandleFromMemento in class SourceType

getChildren

public IJavaElement[] getChildren()
                           throws JavaModelException

Description copied from interface: IParent

Returns the immediate children of this element. Unless otherwise specified by the implementing element, the children are in no particular order.

Specified by:

getChildren in interface IParent

Overrides:

getChildren in class JavaElement

Returns:

the immediate children of this element

Throws:

JavaModelException - if this element does not exist or if an exception occurs while accessing its corresponding resource

See Also:

• IParent

isLocal

public boolean isLocal()

Description copied from interface: IType

Returns whether this type represents a local type. For an anonymous type, this method returns true.

Note: This deviates from JLS3 14.3, which states that anonymous types are not local types since they do not have a name.

Specified by:

isLocal in interface IType

Overrides:

isLocal in class SourceType

Returns:

true if this type represents a local type, false otherwise

See Also:

• IType.isLocal()

resolved

public ResolvedLambdaExpression resolved(Binding binding)

Overrides:

resolved in class SourceType

getMethod

public IMethod getMethod()

isLambda

public boolean isLambda()

Description copied from interface: IType

Returns whether this type represents a lambda expression.

Specified by:

isLambda in interface IType

Overrides:

isLambda in class SourceType

Returns:

true if this type represents a lambda expression, false otherwise

isAnonymous

public boolean isAnonymous()

Description copied from interface: IType

Returns whether this type represents an anonymous type.

Specified by:

isAnonymous in interface IType

Overrides:

isAnonymous in class SourceType

Returns:

true if this type represents an anonymous type, false otherwise

See Also:

• IType.isAnonymous()

toStringName

public void toStringName(StringBuilder buffer)

Description copied from class: JavaElement

Debugging purposes

Overrides:

toStringName in class SourceRefElement

getPrimaryElement

public JavaElement getPrimaryElement(boolean checkOwner)

Overrides:

getPrimaryElement in class SourceType

getSuperInterfaceTypeSignatures

public String[] getSuperInterfaceTypeSignatures()
                                         throws JavaModelException

Description copied from interface: IType

Returns the type signatures of the interfaces that this type implements or extends, in the order in which they are listed in the source.

For classes and enum types, this gives the interfaces that this class implements. For interfaces and annotation types, this gives the interfaces that this interface extends. An empty collection is returned if this type does not implement or extend any interfaces. For anonymous types, an empty collection is always returned.

The type signatures may be either unresolved (for source types) or resolved (for binary types), and either basic (for basic types) or rich (for parameterized types). See Signature for details.

Specified by:

getSuperInterfaceTypeSignatures in interface IType

Overrides:

getSuperInterfaceTypeSignatures in class SourceType

Returns:

the type signatures of interfaces that this type implements or extends, in the order in which they are listed in the source, an empty collection if none

Throws:

JavaModelException - if this element does not exist or if an exception occurs while accessing its corresponding resource.

• IType.getSuperInterfaceTypeSignatures()
