Method Detail

isEOF

public boolean isEOF()

Since an entire block of compressed data is read off of disk, not just a hint at a time, we don't report EOF until the decompressed data has also been read completely

Specified by:

isEOF in interface FileDataInput

Overrides:

isEOF in class RandomAccessReader

Returns:

true if there is no more data to read

reBufferStandard

protected void reBufferStandard()

Overrides:

reBufferStandard in class RandomAccessReader

upgradeInput

public static ChecksummedDataInput upgradeInput(ChecksummedDataInput input,
                                                javax.crypto.Cipher cipher,
                                                ICompressor compressor)
