Method Detail

available

public int available()
              throws java.io.IOException

Overrides:

available in class java.io.InputStream

Returns:

the current number of bytes ready for reading

Throws:

java.io.IOException - if an error occurs

close

public void close()
           throws java.io.IOException

Closes the Stringreader.

Specified by:

close in interface java.io.Closeable

Specified by:

close in interface java.lang.AutoCloseable

Overrides:

close in class java.io.InputStream

Throws:

java.io.IOException - if the original StringReader fails to be closed

mark

public void mark(int limit)

Marks the read limit of the StringReader.

Overrides:

                int off,
                int len)
         throws java.io.IOException

Reads from the Reader into a byte array

Overrides:

read in class java.io.InputStream

Parameters:

b - the byte array to read into

off - the offset in the byte array

len - the length in the byte array to fill

Returns:

the actual number read into the byte array, -1 at the end of the stream

Throws:

java.io.IOException - if an error occurs

reset

public void reset()
           throws java.io.IOException
