streamNo

protected int streamNo

streamInError

protected IOException streamInError

streamCount

protected static int streamCount

newStreamNo

protected static int newStreamNo()

getContentId

public String getContentId()

Get the id for this stream part.

Returns:

the id;

getDimeTypeNameFormat

public DimeTypeNameFormat getDimeTypeNameFormat()

getType

public String getType()

Get the type, as read from the header.

Returns:

the type of this dime

read

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

Read from the DIME stream.

Overrides:

read in class FilterInputStream

Parameters:

b - is the array to read into.

off - is the offset

Returns:

the number of bytes read. -1 if endof stream

Throws:

IOException - if data could not be read from the stream

_read

protected int _read(byte[] b,
                    int off,
                    int len)
             throws IOException

Throws:

IOException

read

public int read(byte[] b)
         throws IOException

Read from the delimited stream.

Overrides:

read in class FilterInputStream

Parameters:

b - is the array to read into. Read as much as possible into the size of this array.

Returns:

the number of bytes read. -1 if endof stream

Throws:

IOException - if data could not be read from the stream

read

public int read()
         throws IOException

Read from the boundary delimited stream.

Overrides:

read in class FilterInputStream

Returns:

the byte read, or -1 if endof stream

Throws:

IOException - if there was an error reading the data

close

public void close()
           throws IOException

Closes the stream.

This will take care of flushing any remaining data to the strea.

Multiple calls to this method will result in the stream being closed once and then all subsequent calls being ignored.

Specified by:

close in interface Closeable

Overrides:

close in class FilterInputStream

Throws:

IOException - if the stream could not be closed

mark

public void mark(int readlimit)

Mark the stream. This is not supported.

Overrides:

mark in class FilterInputStream

reset

public void reset()
           throws IOException

Overrides:

reset in class FilterInputStream

Throws:

IOException

markSupported

public boolean markSupported()

Overrides:

markSupported in class FilterInputStream

available

public int available()
              throws IOException

Overrides:

available in class FilterInputStream

Throws:

IOException

finalClose

protected void finalClose()
                   throws IOException

Throws:
