Method Details

getBytesRead

public long getBytesRead()

Gets the current number of bytes read from this stream.

Returns:

the number of read bytes

Since:

1.1

getCount

@Deprecated
public int getCount()

Deprecated.

this method may yield wrong results for large archives, use #getBytesRead instead

Gets the current number of bytes read from this stream.

Returns:

the number of read bytes

getUncompressedCount

public long getUncompressedCount()

Gets the amount of raw or compressed bytes read by the stream.

This implementation invokes getBytesRead().

Provides half of InputStreamStatistics without forcing subclasses to implement the other half.

Returns:

the amount of decompressed bytes returned by the stream

Since:
