Метод	Описание
Consume ( ) : void
Get ( int i ) : IToken
LA ( int i ) : int
LT ( int i ) : IToken
Mark ( ) : int	Return a marker that we can release later. Return a marker that we can release later. The specific marker value used for this class allows for some level of protection against misuse where `seek()` is called on a mark or `release()` is called in the wrong order.

Seek ( int index ) : void

UnbufferedTokenStream ( ITokenSource tokenSource, int bufferSize ) : System

Защищенные методы

Метод	Описание
Add ( IToken t ) : void
Fill ( int n ) : int	Add n elements to the buffer. Returns the number of tokens actually added to the buffer. If the return value is less than n , then EOF was reached before n tokens could be added.
GetBufferStartIndex ( ) : int
Sync ( int want ) : void	Make sure we have 'need' elements from current position p . Last valid `p` index is `tokens.length-1` . `p+need-1` is the tokens index 'need' elements ahead. If we need 1 element, `(p+1-1)==p` must be less than `tokens.length` .

Add() защищенный Метод

protected Add ( IToken t ) : void
t	IToken
Результат	void

Consume() публичный Метод

public Consume ( ) : void
Результат	void

Fill() защищенный Метод

Add n elements to the buffer. Returns the number of tokens actually added to the buffer. If the return value is less than n , then EOF was reached before n tokens could be added.

protected Fill ( int n ) : int
n	int
Результат	int

Get() публичный Метод

public Get ( int i ) : IToken
i	int
Результат	IToken

GetBufferStartIndex() защищенный Метод

protected GetBufferStartIndex ( ) : int
Результат	int

i	int
Результат	int

LT() публичный Метод

public LT ( int i ) : IToken
i	int
Результат	IToken

Mark() публичный Метод

Return a marker that we can release later.

The specific marker value used for this class allows for some level of protection against misuse where seek() is called on a mark or release() is called in the wrong order.

public Mark ( ) : int
Результат	int

Release() публичный Метод

public Release ( int marker ) : void
marker	int
Результат	void

Seek() публичный Метод

public Seek ( int index ) : void
index	int
Результат	void

Sync() защищенный Метод

Make sure we have 'need' elements from current position p . Last valid p index is tokens.length-1 . p+need-1 is the tokens index 'need' elements ahead. If we need 1 element, (p+1-1)==p must be less than tokens.length .

protected Sync ( int want ) : void
want	int
Результат	void

UnbufferedTokenStream() публичный Метод

Описание свойств

currentTokenIndex защищенное свойство

Absolute token index.

Absolute token index. It's the index of the token about to be read via LT(1) . Goes from 0 to the number of tokens in the entire stream, although the stream size is unknown before the end is reached.

This value is used to set the token indexes if the stream provides tokens that implement IWritableToken .

protected int currentTokenIndex
Результат	int

lastToken защищенное свойство

This is the LT(-1) token for the current position.

protected IToken lastToken
Результат	IToken

lastTokenBufferStart защищенное свойство

When numMarkers > 0 , this is the LT(-1) token for the first token in tokens . Otherwise, this is .

protected IToken lastTokenBufferStart
Результат	IToken

n защищенное свойство

The number of tokens currently in tokens .

This is not the buffer capacity, that's tokens.length .

protected int n
Результат	int

numMarkers защищенное свойство

Count up with mark() and down with release() . When we release() the last mark, numMarkers reaches 0 and we reset the buffer. Copy tokens[p]..tokens[n-1] to tokens[0]..tokens[(n-1)-p] .

protected int numMarkers
Результат	int

p защищенное свойство

0..n-1 index into tokens of next token.

The LT(1) token is tokens[p] . If p == n , we are out of buffered tokens.

protected int p
Результат	int

tokens защищенное свойство

A moving window buffer of the data being scanned.

A moving window buffer of the data being scanned. While there's a marker, we keep adding to buffer. Otherwise, consume() resets so we start filling at index 0 again.

protected IToken[] tokens
Результат	IToken[]
