public interface LocalVariable extends Mirror, Comparable<LocalVariable>
Method
has its own LocalVariable object. Variables of the same
name declared in different scopes have different LocalVariable objects.
LocalVariables can be used alone to retrieve static information
about their declaration, or can be used in conjunction with a
StackFrame
to set and get values.StackFrame

This type name is always available even if the type has not yet been created or loaded.
Type type() throws ClassNotLoadedException
Note: if the type of this variable is a reference type (class,
interface, or array) and it has not been created or loaded
by the class loader of the enclosing class,
then ClassNotLoadedException will be thrown.
Also, a reference type may have been loaded but not yet prepared,
in which case the type will be returned
but attempts to perform some operations on the returned type
(e.g. fields()
) will throw
a ClassNotPreparedException
.
Use ReferenceType.isPrepared()
to determine if
a reference type is prepared.
