Method Detail

closing

protected void closing(java.lang.Object info)

Description copied from class: SourceRefElement

This element is being closed. Do any necessary cleanup.

Overrides:

closing in class SourceRefElement

createElementInfo

protected java.lang.Object createElementInfo()

Description copied from class: SourceRefElement

Returns a new element info for this element.

Overrides:

createElementInfo in class SourceRefElement

equals

public boolean equals(java.lang.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 SourceRefElement

See Also:

Object.equals(java.lang.Object)

exists

public boolean exists()

Description copied from interface: IJavaElement

Returns whether this Java element exists in the model.

Java elements are handle objects that may or may not be backed by an actual element. Java elements that are backed by an actual element are said to "exist", and this method returns true. For Java elements that are not working copies, it is always the case that if the element exists, then its parent also exists (provided it has one) and includes the element as one of its children. It is therefore possible to navigated to any existing Java element from the root of the Java model along a chain of existing Java elements. On the other hand, working copies are said to exist until they are destroyed (with IWorkingCopy.destroy). Unlike regular Java elements, a working copy never shows up among the children of its parent element (which may or may not exist).

Specified by:

exists in interface IJavaElement

Specified by:

exists in interface ISourceReference

Overrides:

exists in class JavaElement

Returns:

true if this element exists in the Java model, and false if this element does not exist
