Examples of org.eclipse.jdt.core.ILocalVariable

org.eclipse.jdt.core.ILocalVariable
Represents a local variable declared in a method or an initializer. ILocalVariable are pseudo-elements created as the result of a ICodeAssist.codeSelect(...) operation. They are not part of the Java model (exists() returns whether the parent exists rather than whether the local variable exists in the parent) and they are not included in the children of an IMethod or an IInitializer.
In particular such a pseudo-element should not be used as a handle. For example its name range won't be updated if the underlying source changes.
@since 3.0 @noimplement This interface is not intended to be implemented by clients.
