Method Detail

encode

public byte[] encode(BSONObject document)

Description copied from interface: BSONEncoder

Encode a document into byte array. This is a shortcut method which creates a new OutputBuffer, invokes the other 3 methods in a corresponding sequence:

• BSONEncoder.set(org.bson.io.OutputBuffer)
• BSONEncoder.putObject(BSONObject)
• BSONEncoder.done()

and returns the contents of the OutputBuffer.

Specified by:

encode in interface BSONEncoder

Parameters:

document - the document to be encoded

Returns:

a byte sequence

done

public void done()

Description copied from interface: BSONEncoder

Free the resources.

Specified by:

done in interface BSONEncoder

set

public void set(OutputBuffer buffer)

Description copied from interface: BSONEncoder

Sets the buffer to wrich the result of encoding will be written.

Specified by:

set in interface BSONEncoder

Parameters:

buffer - the buffer to be used to write a byte sequences to

putObject

public int putObject(BSONObject document)

Encodes a BSONObject. This is for the higher level api calls.

Specified by:

putObject in interface BSONEncoder

Parameters:

document - the document to encode

Returns:

the number of characters in the encoding
