Constructor Detail

BinaryImpl

public BinaryImpl(InputStream in)
           throws IOException

Creates a new BinaryImpl instance from an InputStream. The contents of the stream is spooled to a temporary file or to a byte buffer if its size is smaller than MAX_BUFFER_SIZE.

Parameters:

in - stream to be represented as a BLOBFileValue instance

Throws:

IOException - if an error occurs while reading from the stream or writing to the temporary file

BinaryImpl

public BinaryImpl(byte[] buffer)

Creates a new BinaryImpl instance from a byte[] array.

Parameters:

buffer - byte array to be represented as a BinaryImpl instance

Method Detail

getStream

public InputStream getStream()
                      throws RepositoryException

Returns an InputStream representation of this value. Each call to getStream() returns a new stream. The API consumer is responsible for calling close() on the returned stream.

If Binary.dispose() has been called on this Binary object, then this method will throw the runtime exception IllegalStateException.

Specified by:

getStream in interface Binary

Returns:

A stream representation of this value.

Throws:

RepositoryException - if an error occurs.

read

public int read(byte[] b,
                long position)
         throws IOException,
                RepositoryException

Reads successive bytes from the specified position in this Binary into the passed byte array until either the byte array is full or the end of the Binary is encountered.

If Binary.dispose() has been called on this Binary object, then this method will throw the runtime exception IllegalStateException.

Specified by:

read in interface Binary

Parameters:

b - the buffer into which the data is read.

position - the position in this Binary from which to start reading bytes.

Returns:

the number of bytes read into the buffer, or -1 if there is no more data because the end of the Binary has been reached.

Throws:

IOException - if an I/O error occurs.

RepositoryException - if another error occurs.

getSize

public long getSize()
             throws RepositoryException

Returns the size of this Binary value in bytes.

If Binary.dispose() has been called on this Binary object, then this method will throw the runtime exception IllegalStateException.

Specified by:

getSize in interface Binary

Returns:

the size of this value in bytes.

Throws:

RepositoryException - if an error occurs.

dispose

public void dispose()

Releases all resources associated with this Binary object and informs the repository that these resources may now be reclaimed. An application should call this method when it is finished with the Binary object.

Specified by:

dispose in interface Binary
