Examples of org.apache.xerces.util.SymbolTable

org.apache.xerces.util.SymbolTable
This class is a symbol table implementation that guarantees that strings used as identifiers are unique references. Multiple calls to addSymbol will always return the same string reference.
The symbol table performs the same task as String.intern() with the following differences:
- A new string object does not need to be created in order to retrieve a unique reference. Symbols can be added by using a series of characters in a character array.
- Users of the symbol table can provide their own symbol hashing implementation. For example, a simple string hashing algorithm may fail to produce a balanced set of hashcodes for symbols that are mostly unique. Strings with similar leading characters are especially prone to this poor hashing behavior.
