JdkMapAdapterStringMap

public JdkMapAdapterStringMap(Map<String,String> map,
 boolean frozen)

Constructs a new StringMap, based on a JDK map.

The underlying map should not be modified after this call.

If the Map implementation does not allow modifications, frozen should be set to true.

Parameters:

map - a JDK map,

frozen - if true this collection will be immutable.
