public interface ISourceConstructImplSupport extends ISourceElementImplSupport, ISourceConstructImplExtension
ISourceConstructImplExtension to minimize the effort required to implement
that interface. Clients may implement ("mix in") this interface directly or
extend SourceConstruct.
In general, the members first defined in this interface are not intended to be referenced outside the subtype hierarchy.

This implementation throws assertion error; the openable parent builds
the whole structure in one go.

an interface, but clients can implement equals by

A default implementation of

an interface, but clients can implement hashCode by
delegating to this default method. |

Returns whether this element exists in the model.

This implementation always returns
false. |

This implementation throws assertion error; the openable parent builds
the whole structure and determines child existence.

IElementImplSupportIElement.hashCode() cannot be provided in
an interface, but clients can implement hashCode by
delegating to this default method.
By default, the hash code for an element is a combination of hash codes
for its name and its parent element. This method is specialized in ISourceConstructImplSupport to include the element's occurrence count,
and in ISourceFileImplSupport to return the hash code for the
underlying file object, if there is one. This method is not intended
to be replaced by clients; if necessary, clients should override
hashCode directly.

IElementImplSupportIElement.equals(Object) cannot be provided in
an interface, but clients can implement equals by
delegating to this default method.
By default, two elements that implement this interface are equal if they
are identical or if they can equal each other
and do have equal names and equal parents. This method is specialized in
ISourceConstructImplSupport and ISourceFileImplSupport
to also compare occurrence counts and underlying file objects
respectively. This method is not intended to be replaced by clients;
if necessary, clients should override equals directly.

and false otherwisedefault boolean exists_()
Handles may or may not be backed by an actual element. Handles that are backed by an actual element are said to "exist".
This implementation returns true if there is a cached body
for this element; otherwise, attempts to open this element to determine the result.
