Method Detail
-
count
protected void count(int read)
Increments the counter of already read bytes. Doesn't increment if the EOF has been hit (read == -1)- Parameters:
read
- the number of bytes read- Since:
- 1.1
-
count
protected void count(long read)
Increments the counter of already read bytes. Doesn't increment if the EOF has been hit (read == -1)- Parameters:
read
- the number of bytes read
-
pushedBackBytes
protected void pushedBackBytes(long pushedBack)
Decrements the counter of already read bytes.- Parameters:
pushedBack
- the number of bytes pushed back.- Since:
- 1.7
-
getCount
@Deprecated public int getCount()
Deprecated.this method may yield wrong results for large archives, use #getBytesRead insteadReturns the current number of bytes read from this stream.- Returns:
- the number of read bytes
-
getBytesRead
public long getBytesRead()
Returns the current number of bytes read from this stream.- Returns:
- the number of read bytes
- Since:
- 1.1
-
getUncompressedCount
public long getUncompressedCount()
Returns 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:
- 1.17
