Parameters:

symbol - The new symbol.

Overrides:

addSymbol in class SymbolTable

addSymbol

public java.lang.String addSymbol(char[] buffer,
                                  int offset,
                                  int length)

Adds the specified symbol to the symbol table and returns a reference to the unique symbol. If the symbol already exists, the previous symbol reference is returned instead, in order guarantee that symbol references remain unique.

Parameters:

buffer - The buffer containing the new symbol.

offset - The offset into the buffer of the new symbol.

length - The length of the new symbol in the buffer.

Overrides:

addSymbol in class SymbolTable

hash

public int hash(java.lang.String symbol)

Returns a hashcode value for the specified symbol. The value returned by this method must be identical to the value returned by the hash(char[],int,int) method when called with the character array that comprises the symbol string.

Parameters:

symbol - The symbol to hash.

Overrides:

hash in class SymbolTable

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 the hash(String) method when called with the string object created from the symbol information.

Parameters:

buffer - The character buffer containing the symbol.

offset - The offset into the character buffer of the start of the symbol.

length - The length of the symbol.

Overrides:

hash in class SymbolTable
