length

public long length()

Specified by:

length in interface Range<BlockRange<T extends Range<T>>>

Returns:

Length of this data range

getSubrange

public BlockRange<T> getSubrange(long offset,
                                 long length)

Description copied from interface: Range

Build a subrange of this data range.

Specified by:

getSubrange in interface Range<BlockRange<T extends Range<T>>>

Parameters:

offset - Offset from the beginning of the original data range in bytes, inclusive

length - Length of the new data range

Returns:

Subrange of the original data range

getSubrange

public BlockRange<T> getSubrange(long offset)

Description copied from interface: Range

Build a subrange of this data range.

Specified by:

getSubrange in interface Range<BlockRange<T extends Range<T>>>

Parameters:

offset - Offset from the beginning of the original data range in bytes, inclusive

Returns:
