readInternal
protected abstract void readInternal(byte[] b,
int offset,
int length)
throws IOException
- Expert: implements buffer refill. Reads bytes from the current position in
the input.
- Parameters:
b
- the array to read bytes intooffset
- the offset in the array to start storing byteslength
- the number of bytes to read
- Throws:
IOException
getFilePointer
public long getFilePointer()
- Specified by:
getFilePointer
in class IndexInput
seek
public void seek(long pos)
throws IOException
- Specified by:
seek
in class IndexInput
- Throws:
IOException
seekInternal
protected abstract void seekInternal(long pos)
throws IOException
- Expert: implements seek. Sets current position in this file, where the next
readInternal(byte[],int,int)
will occur.
- Throws:
IOException
- See Also:
readInternal(byte[],int,int)
clone
public IndexInput clone()
- Overrides:
clone
in class IndexInput
flushBuffer
protected int flushBuffer(IndexOutput out,
long numBytes)
throws IOException
- Flushes the in-memory bufer to the given output, copying at most
numBytes
.
NOTE: this method does not refill the buffer, however it does
advance the buffer position.
- Returns:
- the number of bytes actually flushed from the in-memory buffer.
- Throws:
IOException
