Method Detail

read

public int read()
         throws java.io.IOException

Overrides:

read in class java.io.FilterInputStream

Throws:

java.io.IOException

read

public int read(byte[] b,
                int off,
                int len)
         throws java.io.IOException

Overrides:

read in class java.io.FilterInputStream

Throws:

java.io.IOException

readLine

public int readLine(ByteArrayBuffer dst)
             throws MaxLineLimitException,
                    java.io.IOException

Description copied from class: LineReaderInputStream

Reads one line of text into the given ByteArrayBuffer.

Specified by:

readLine in class LineReaderInputStream

Parameters:

dst - Destination

Returns:

number of bytes copied or -1 if the end of the stream has been reached.

Throws:

MaxLineLimitException - if the line exceeds a limit on the line length imposed by a subclass.

java.io.IOException - in case of an I/O error.

doReadLine

private int doReadLine(ByteArrayBuffer dst)
                throws MaxLineLimitException,
                       java.io.IOException

Throws:

MaxLineLimitException

java.io.IOException

eof

public boolean eof()

isUsed

public boolean isUsed()

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

unread

public boolean unread(ByteArrayBuffer buf)

Description copied from class: LineReaderInputStream

Tries to unread the last read line. Implementation may refuse to unread a new buffer until the previous unread one has been competely consumed. Implementations will directly use the byte array backed by buf, so make sure to not alter it anymore once this method has been called.

Specified by:

unread in class LineReaderInputStream

Returns:

true if the unread has been succesfull.

unread

public boolean unread(RecycledByteArrayBuffer buf)

Specified by:

unread in class LineReaderInputStream

skip

public long skip(long count)
          throws java.io.IOException

Overrides:

skip in class java.io.FilterInputStream

Throws:

java.io.IOException
