Constructors

public DictionaryByteRange(ByteRange byteRange, boolean isExact)#

Parameters:

byteRange – byte range to read from the file
isExact – whether byteRange is exactly the dictionary page, not an upper bound

Methods

public ByteRange byteRange()#

Returns:: the byte range this dictionary page lies in.

public boolean isExact()#

Returns:: whether byteRange() is exactly the dictionary page, not an upper bound.

public ByteRange byteRangeToRead(long maxUpperBoundSize)#

The byte range to read, reading no more than maxUpperBoundSize bytes of a range that is not exact.

What is read of such a range must still be trimmed to the dictionary page before it is handed to the reader; see HybridScanReader.dictionaryPageLengths.

Parameters:: maxUpperBoundSize – most bytes to read of a range that is not exact
Returns:: the byte range to read
