Symbol
public class Symbol extends OString implements Externalizable(Code)
The Symbol is a type used internally by the scripting engine to represent identifiers, ie. variable or function names. Each symbol has a unique integer id. Furthermore, the mapping between symbols and ids is preserved in /cache so any cache entries (ie. compiled code, etc.) can assume that the same mapping between symbol and id exists as when it was created. (In other words, compiled code can discard the symbol object, and put the symbol's id in it's constant table.)

Constructor Detail
Symbol
public Symbol()(Code)




Method Detail
getId
public int getId()(Code)
Get the unique id for this symbol. If two symbols are equal (in terms of Symbol.bopEquals ), then they will map to the same id, and likewise the id will always map to symbols that are equal. the integer id



getSymbol
public static Symbol getSymbol(Value val)(Code)
Given a script object, return a symbol object. If two objects have the same string representation ( Symbol.castToString ) then they will always map to the same symbol.



getSymbol
public static synchronized Symbol getSymbol(String str)(Code)
Given a string, return a symbol object. If two strings are equals() then they will always map to the same symbol.



getSymbol
public static Symbol getSymbol(int id)(Code)
Given a symbol id, return the symbol object. The same integer id will always map to the same symbol. If a symbol with the specified id does not exist, this will return null.



readExternal
public void readExternal(ObjectInput in) throws IOException(Code)
Derived class that implements java.io.Externalizable must call this if it overrides it. It should override it to save/restore it's own state.



writeExternal
public void writeExternal(ObjectOutput out) throws IOException(Code)
Derived class that implements java.io.Externalizable must call this if it overrides it. It should override it to save/restore it's own state.
