C# Class iTextSharp.xmp.impl.PushbackReader

A character-stream reader that allows characters to be pushed back into the stream. @author Mark Reinhold @since JDK1.1

Inheritance: FilterReader

Public Methods

Method	Description
Close ( ) : void	Closes the stream and releases any system resources associated with it. Once the stream has been closed, further read(), unread(), ready(), or skip() invocations will throw an IOException. Closing a previously closed stream has no effect.
PushbackReader ( TextReader inp ) : System	Creates a new pushback reader with a one-character pushback buffer.
PushbackReader ( TextReader inp, int size ) : System	Creates a new pushback reader with a pushback buffer of the given size.
Read ( ) : int	Reads a single character.
Read ( char cbuf, int off, int len ) : int	Reads characters into a portion of an array.
Unread ( char cbuf ) : void	Pushes back an array of characters by copying it to the front of the pushback buffer. After this method returns, the next character to be read will have the value `cbuf[0]`, the character after that will have the value `cbuf[1]`, and so forth.
Unread ( char cbuf, int off, int len ) : void	Pushes back a portion of an array of characters by copying it to the front of the pushback buffer. After this method returns, the next character to be read will have the value `cbuf[off]`, the character after that will have the value `cbuf[off+1]`, and so forth.
Unread ( int c ) : void	Pushes back a single character by copying it to the front of the pushback buffer. After this method returns, the next character to be read will have the value `(char)c`.

Private Methods

EnsureOpen ( ) : void	Checks to make sure that the stream has not been closed.

Method Details

Close() public method

Closes the stream and releases any system resources associated with it. Once the stream has been closed, further read(), unread(), ready(), or skip() invocations will throw an IOException. Closing a previously closed stream has no effect.

If an I/O error occurs

public Close ( ) : void
return	void

PushbackReader() public method

Creates a new pushback reader with a one-character pushback buffer.

public PushbackReader ( TextReader inp ) : System
inp	TextReader
return	System

PushbackReader() public method

Creates a new pushback reader with a pushback buffer of the given size.

if size is <= 0

public PushbackReader ( TextReader inp, int size ) : System
inp	TextReader
size	int	The size of the pushback buffer
return	System

Read() public method

Reads a single character.

If an I/O error occurs

public Read ( ) : int
return	int

Read() public method

Reads characters into a portion of an array.

If an I/O error occurs

public Read ( char cbuf, int off, int len ) : int
cbuf	char	Destination buffer
off	int	Offset at which to start writing characters
len	int	Maximum number of characters to read ///
return	int

Unread() public method

Pushes back an array of characters by copying it to the front of the pushback buffer. After this method returns, the next character to be read will have the value cbuf[0], the character after that will have the value cbuf[1], and so forth.

If there is insufficient room in the pushback /// buffer, or if some other I/O error occurs

public Unread ( char cbuf ) : void
cbuf	char	Character array to push back ///
return	void

Unread() public method

Pushes back a portion of an array of characters by copying it to the front of the pushback buffer. After this method returns, the next character to be read will have the value cbuf[off], the character after that will have the value cbuf[off+1], and so forth.

If there is insufficient room in the pushback /// buffer, or if some other I/O error occurs

public Unread ( char cbuf, int off, int len ) : void
cbuf	char	Character array
off	int	Offset of first character to push back
len	int	Number of characters to push back ///
return	void

Unread() public method

Pushes back a single character by copying it to the front of the pushback buffer. After this method returns, the next character to be read will have the value (char)c.

If the pushback buffer is full, /// or if some other I/O error occurs

public Unread ( int c ) : void
c	int	The int value representing a character to be pushed back ///
return	void
