HttpMultipartInputStream

protected HttpMultipartInputStream(InputStream in,
                                   byte[] boundary)

Method Detail

read

public int read()
         throws IOException

Overrides:

read in class FilterInputStream

Throws:

IOException

read

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

Overrides:

read in class FilterInputStream

Throws:

IOException

skip

public long skip(long len)
          throws IOException

Overrides:

skip in class FilterInputStream

Throws:

IOException

available

public int available()
              throws IOException

Overrides:

available in class FilterInputStream

Throws:

IOException

markSupported

public boolean markSupported()

Overrides:

markSupported in class FilterInputStream

nextPart

public boolean nextPart()
                 throws IOException

Advances the stream position to the beginning of the next part. Data read before calling this method for the first time is the preamble, and data read after this method returns false is the epilogue.

Returns:

true if successful, or false if there are no more parts

Throws:

IOException - if an error occurs

fill

protected boolean fill()
                throws IOException

Fills the buffer with more data from the underlying stream.

Returns:

true if there is available data for the current part, or false if the current part's end has been reached

Throws:

IOException - if an error occurs or the input format is invalid

findBoundary

protected void findBoundary()
                     throws IOException

Finds the first (potential) boundary within the buffer's remaining data. Updates tail, length and state fields accordingly.

Throws:

IOException - if an error occurs or the input format is invalid
