Method Detail

isKeys

public final boolean isKeys()

Description copied from interface: IRaba

When true the IRaba supports search and elements are interpreted as unsigned byte[]s (B+Tree keys). For this case the application MUST ensure that the elements are maintained in unsigned byte[] order and that duplicates byte[]s are not stored.

When false, the IRaba allows nulls and the elements are interpreted as signed byte[] (B+Tree values).

Returns:

true if the IRaba represents B+Tree keys and false if it represents B+Tree values.
