Examples of org.eclipse.jdt.core.ISourceRange

org.eclipse.jdt.core.ISourceRange
A source range defines an element's source coordinates relative to its source buffer.
Clients may use the method {@link org.eclipse.jdt.core.SourceRange#isAvailable(ISourceRange)}in order to find out if a source range is available. This method returns false when the source range offset is equals to -1.

Clients may use the default implementation provided by {@link SourceRange}.
@see SourceRange @noimplement This interface is not intended to be implemented by clients.
