Constructor Detail

LineNumberReader

public LineNumberReader(Reader reader)

Parameters:

reader - ?

LineNumberReader

public LineNumberReader(Reader reader,
                        int i)

Parameters:

reader - ?

i - ?

Method Detail

getLineNumber

public int getLineNumber()

Returns:

?

mark

public void mark(int i)
          throws IOException

Description copied from class: BufferedReader

Marks a position in the buffered stream. A call to reset() will reposition the buffer pointer to the current position. This provides for a lookahead mechanism where characters may be read, the buffer reset() and the data made available to be read once more.

Overrides:

mark in class BufferedReader

Parameters:

i - ?

Throws:

IOException - ?

read

public int read()
         throws IOException

Description copied from class: BufferedReader

Reads a single character. If the readline() method had been previously used and terminated by a carriage return \r this will ignore any following linefeed \n.

Overrides:

read in class BufferedReader

Returns:

?

Throws:

IOException - ?

read

public int read(char[] ac,
                int i,
                int j)
         throws IOException

Description copied from class: BufferedReader

Reads characters into part of a character array. If readLine() was previously used and terminated by a carriage return \r any following linefeed \n will be ignored.

Overrides:

read in class BufferedReader

Parameters:

ac - ?

i - ?

j - ?

Returns:

?

Throws:

IOException - ?

readLine

public String readLine()
                throws IOException

Description copied from class: BufferedReader

Returns the next line of text from the stream (blocking). This will return a partial line if the stream runs dry.

Overrides:

readLine in class BufferedReader

Returns:

?

Throws:

IOException - ?

reset

public void reset()
           throws IOException

Description copied from class: BufferedReader

Resets the buffer pointer. If mark() has been called then the buffer pointer is moved back to that position and subsequent data may be reread.

Overrides:

reset in class BufferedReader

Throws:

IOException - ?

setLineNumber

public void setLineNumber(int i)

Parameters:

i - ?

skip

public long skip(long l)
          throws IOException

Description copied from class: BufferedReader

Skips the specified number of characters in the stream (blocking). If readLine() had been previously used and the line terminated with a carriage return \r then any following linefeed \n is ignored and not counted.

Overrides:

skip in class BufferedReader

Parameters:

l - ?

Returns:

?

Throws:

IOException - ?
