Constructor Detail

MaxSizeInputStream

public MaxSizeInputStream(java.io.InputStream is,
                          long l)

Creates a new MaxSizeInputStream with a given limit on the given stream.

Method Detail

available

public int available()
              throws java.io.IOException

Get the number of bytes ready for reading.

Returns:

the number of bytes that can be read without blocking.

Throws:

java.io.IOException - if an I/O error occurs.

read

public int read()
         throws java.io.IOException

Reads the next byte of data from this input stream. The value byte is returned as an int in the range 0 to 255. If no byte is available because the end of the stream has been reached, the value -1 is returned. This method blocks until input data is available, the end of the stream is detected, or an exception is thrown.

Returns:

the next byte of data, or -1 if the end of the stream is reached.

Throws:

java.io.IOException - if an I/O error occurs.

read

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

Read a block of data (up to b.length bytes).

Returns:

the number of byte actually read.

Throws:

java.io.IOException - if an I/O error occurs.

read

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

Read a block of data (up to len bytes).

Returns:

the number of byte actually read.

Throws:

java.io.IOException - if an I/O error occurs.

skip

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

Skip a number of bytes.

Returns:

the number of byte actually skipped.

Throws:

java.io.IOException - if an I/O error occurs.
