Method Detail

addSymbol

public String addSymbol(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 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(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.
