Method Detail

validateIoByteCount

static long validateIoByteCount(long specifiedByteCount,
                                long actualByteCount)

write

default long write(StorageFile file,
                   Iterable<? extends ByteBuffer> buffers)

writeStore

default long writeStore(StorageLiveDataFile targetFile,
                        Iterable<? extends ByteBuffer> byteBuffers)

writeImport

default long writeImport(StorageFile sourceFile,
                         long sourceOffset,
                         long copyLength,
                         StorageLiveDataFile targetFile)

Logically the same as a store, but technically the same as a transfer with an external source file.

Parameters:

sourceFile - the source file

sourceOffset - the source offset

copyLength - the copy length

targetFile - the target file

Returns:

the amount of bytes written
