Examples of sun.tools.java.Identifier

sun.tools.java.Identifier
A class to represent identifiers.
An identifier instance is very similar to a String. The difference is that identifier can't be instanciated directly, instead they are looked up in a hash table. This means that identifiers with the same name map to the same identifier object. This makes comparisons of identifiers much faster.
A lot of identifiers are qualified, that is they have '.'s in them. Each qualified identifier is chopped up into the qualifier and the name. The qualifier is cached in the value field.
Unqualified identifiers can have a type. This type is an integer that can be used by a scanner as a token value. This value has to be set using the setType method.
