Constructor Detail

SlowCollatedTermRangeTermsEnum

public SlowCollatedTermRangeTermsEnum(TermsEnum tenum,
                              String lowerTermText,
                              String upperTermText,
                              boolean includeLower,
                              boolean includeUpper,
                              Collator collator)

Deprecated.

Enumerates all terms greater/equal than lowerTerm but less/equal than upperTerm. If an endpoint is null, it is said to be "open". Either or both endpoints may be open. Open endpoints may not be exclusive (you can't select all but the first or last term without explicitly specifying the term to exclude.)

Parameters:

tenum - source of the terms to enumerate.

lowerTermText - The term text at the lower end of the range

upperTermText - The term text at the upper end of the range

includeLower - If true, the lowerTerm is included in the range.

includeUpper - If true, the upperTerm is included in the range.

collator - The collator to use to collate index Terms, to determine their membership in the range bounded by lowerTerm and upperTerm.
