```
public ProtocolRestrictor(java.lang.String value)
```
    Create a predicate from a list of allowed protocols.
    The value is a comma-separated list of permitted protocols. A protocol is the scheme portion of a URI, or in the case of the JAR protocol, "jar" plus the scheme portion separated by colon. The value "all" gives access to all protocols (which is the default). The value "" (empty string) disallows all external resource access. (The format is thus the same as for XMLConstants.ACCESS_EXTERNAL_SCHEMA and similar attributes.)
    
    Parameters:
    
    value - the list of allowed protocols
