inline

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

Parameters

in	The reader from which characters will be read
size	The size of the pushback buffer

PushbackReader() [2/2]

iText.Commons.Utils.PushbackReader.PushbackReader ( TextReader  inp )

inline

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

Parameters

in	The reader from which characters will be read

Member Function Documentation

Dispose()

override void iText.Commons.Utils.PushbackReader.Dispose ( bool  disposing )

inlineprotected

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.

Read() [1/2]

override int iText.Commons.Utils.PushbackReader.Read ( )

inline

Reads a single character.

Returns

The character read, or -1 if the end of the stream has been reached

Read() [2/2]

override int iText.Commons.Utils.PushbackReader.Read ( char[]  cbuf, int  off, int  len  )

inline

Reads characters into a portion of an array.

Parameters

cbuf	Destination buffer
off	Offset at which to start writing characters
len	Maximum number of characters to read

Returns

The number of characters read, or -1 if the end of the stream has been reached

Unread() [1/3]

virtual void iText.Commons.Utils.PushbackReader.Unread ( char[]  cbuf )

inlinevirtual

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.

Parameters

cbuf	Character array to push back

Unread() [2/3]

virtual void iText.Commons.Utils.PushbackReader.Unread ( char[]  cbuf, int  off, int  len  )

inlinevirtual

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.

Parameters

cbuf	Character array
off	Offset of first character to push back
len	Number of characters to push back

Unread() [3/3]

virtual void iText.Commons.Utils.PushbackReader.Unread ( int  c )

inlinevirtual

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.

Parameters

c	The int value representing a character to be pushed back
