Method Detail

write

long write(String path,
           ReadableByteChannel data,
           ByteBuffer temporaryBuffer,
           boolean hasData,
           int requiredElementAlignment)
    throws IOException

Pipe the data from the given ReadableByteChannel to a location given by the path, using the given temporaryBuffer for buffering if necessary. The hasData is an effect of the block format not supporting a zero length blocks, whereas a neostore file may actually be 0 bytes we'll have to keep track of that special case. The requiredElementAlignment parameter specifies the size in bytes to which the transferred elements should be aligned. For record store files, this is the record size. For files that have no special alignment requirements, you should use the value 1 to signify that any alignment will do.

IOException
