method when called with the character array that comprises the symbol string.- Overrides:
hash
in classSymbolTable
- Parameters:
symbol
- The symbol to hash.
-
hash
public int hash(char[] buffer, int offset, int length) Returns a hashcode value for the specified symbol information. The value returned by this method must be identical to the value returned by thehash(String)
method when called with the string object created from the symbol information.- Overrides:
