Field Detail

### fSymbolTable

    protected SymbolTable fSymbolTable

  Main symbol table.

Constructor Detail

### SynchronizedSymbolTable

    public SynchronizedSymbolTable(SymbolTable symbolTable)

  Constructs a synchronized symbol table.

### SynchronizedSymbolTable

    public SynchronizedSymbolTable()

### SynchronizedSymbolTable

    public SynchronizedSymbolTable(int size)

Method Detail

### addSymbol

    public java.lang.String addSymbol(java.lang.String symbol)

  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.

  Overrides:
    `addSymbol` in class `SymbolTable`
  Parameters:
    `symbol` - The new symbol.

### 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.

  Overrides:
    `addSymbol` in class `SymbolTable`
  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.

### containsSymbol

    public boolean containsSymbol(java.lang.String symbol)

  Returns true if the symbol table already contains the specified symbol.

  Overrides:
    `containsSymbol` in class `SymbolTable`
  Parameters:
    `symbol` - The symbol to look for.

### containsSymbol

    public boolean containsSymbol(char[] buffer,
                                  int offset,
                                  int length)

  Returns true if the symbol table already contains the specified symbol.

  Overrides:
    `containsSymbol` in class `SymbolTable`
  Parameters:
    `buffer` - The buffer containing the symbol to look for.
    `offset` - The offset into the buffer.
    `length` - The length of the symbol in the buffer.
