Examples of org.rhq.core.util.TokenReplacingProperties

org.rhq.core.util.TokenReplacingProperties
This map is basically an extension of the {@link Properties} class that can resolve the referencesto values of other keys inside the values.
I.e., if the map is initialized with the following mappings:
name=> world hello=> Hello ${name}!
then the call to:
get("hello")
will return: "Hello world!"
To access and modify the underlying unprocessed values, one can use the "raw" counterparts of the standard map methods (e.g. instead of {@link #get(Object)}, use {@link #getRaw(Object)}, etc.). @author Lukas Krejci
