nextByChunk

public boolean nextByChunk()

Description copied from class: ByteArrayChunkCompare

Advances the index of the byte array source to the next byte chunk. In other words, advances the index by the value of the ComparisonChunkSize value in AppConfig.

Overrides:

nextByChunk in class ByteArrayChunkCompare

Returns:

true if the index advanced successfully. false if the end of the source byte array has been reached.

nextByByte

public boolean nextByByte()

Description copied from class: ByteArrayChunkCompare

Advances the index of the byte array source by 1 byte.

Overrides:

nextByByte in class ByteArrayChunkCompare

Returns:

true if the index advanced successfully. false if the end of the source byte array has been reached.

setIndex

public void setIndex(int index)
              throws EndOfSourceException

Explicitly sets the index value.

Overrides:

setIndex in class ByteArrayChunkCompare

Throws:

EndOfSourceException - -- Requested index is not in source byte array.

setIndex

public void setIndex(int index,
                     boolean optimistic)
              throws EndOfSourceException

Explicitly sets the index value.

Parameters:

index - -- the index to move to.

optimistic - -- means "discard before" value is not modified.

Throws:

EndOfSourceException - -- Requested index is not in source byte array.

isFileIndexInCurrentBuffer

getSizeOfSource

public int getSizeOfSource()

Overrides:

getSizeOfSource in class ByteArrayChunkCompare

equals

public boolean equals(java.lang.Object o)

Tests if the current chunk of bytes in this ByteArrayChunkCompare object is equal to the current chunk of bytes in o.

Overrides:

equals in class ByteArrayChunkCompare
