### StringBvr Methods

newUninitBvr

####

extract

StringBvr Class

newUninitBvr

StringBvr Class

Allows you to refer to an StringBvr behavior before that behavior has been defined. With this method you can create the behavior and use it in the definition of other behaviors, but not actually define its contents until some later point. (This is accomplished with the init method, which is available on all behaviors.) The system generates a run-time error if you initialize a non-uninitialized behavior, initialize an uninitialized behavior that has already been initialized, or run an initialized behavior that has not yet been initialized.

public static StringBvr newUninitBvr( );

##### Parameters

b
  A character string.

##### Return Values

Returns the StringBvr object.

### Relevant Methods from the Statics Class

The following methods are defined in the Statics class and are most relevant to objects of type StringBvr.

public static StringBvr concat(StringBvr a, StringBvr b);

public static StringBvr toBvr(String string);
