author:

version:
   1.0



Field Summary
protected  SymbolNode[]children
    

Constructor Summary
public  SymbolRootNode()
     Create and initialize a root node.

Method Summary
public  voidadd(String s)
     Add the given string as a symbol.
public  Stringancestry()
     A root node has no parent and no character of its own, so its ancestry is "".
protected  SymbolNodefindChildWithChar(char c)
     A root node maintains its children in an array instead of a ArrayList, to be faster.
protected  voidinit()
     Set all possible symbols to be valid children.
public  StringnextSymbol(PushbackReader r, int first)
     Return a symbol string from a reader.

Field Detail
children
protected SymbolNode[] children(Code)




Constructor Detail
SymbolRootNode
public SymbolRootNode()(Code)
Create and initialize a root node.




Method Detail
add
public void add(String s)(Code)
Add the given string as a symbol.
Parameters:
  String - the character sequence to add



ancestry
public String ancestry()(Code)
A root node has no parent and no character of its own, so its ancestry is "". an empty string



findChildWithChar
protected SymbolNode findChildWithChar(char c)(Code)
A root node maintains its children in an array instead of a ArrayList, to be faster.



init
protected void init()(Code)
Set all possible symbols to be valid children. This means that the decision of which characters are valid one- character symbols lies outside this tree. If a tokenizer asks this tree to produce a symbol, this tree assumes that the first available character is a valid symbol.



nextSymbol
public String nextSymbol(PushbackReader r, int first) throws IOException(Code)
Return a symbol string from a reader.
Parameters:
  PushbackReader - a reader to read from int the first character of this symbol, alreadyread from the reader a symbol string from a reader
