Interface FirebirdBlob.BlobOutputStream

All Known Implementing Classes:

FBBlobOutputStream

Enclosing interface:

FirebirdBlob

public static interface FirebirdBlob.BlobOutputStream

Blob output stream. This interface defines methods to write contents of the Blob field. Some method signatures are copied from the OutputStream only because it is abstract class and not interface that we can extend.

Method Summary

Modifier and Type	Method and Description
void	close() Close this stream.
long	length() Get Blob length.
void	write(byte[] buffer, int offset, int length) Write data from the buffer into this stream.
void	write(int data) Write single byte into the stream.

Method Detail

close

void close()
    throws java.io.IOException

Close this stream. Calling this method closes Blob stream and moves Blob from temporary into permanent state making any further content updates impossible.

Throws:

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

length

long length()
     throws java.io.IOException

Get Blob length. This method is the only available way to obtain length of a Blob that is in temporary state,

Returns:

length of the blob.

Throws:

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

write

void write(byte[] buffer,
           int offset,
           int length)
    throws java.io.IOException

Write data from the buffer into this stream.

Parameters:

buffer - buffer from which data should be written.

offset - offset in the buffer.

length - number of bytes to write.

Throws:

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

write

void write(int data)
    throws java.io.IOException

Write single byte into the stream.

Parameters:

data - data to write, only lowest 8 bits are written.

Throws:

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