static MultiDocValues.OrdinalMap |
build(Object owner,
SortedDocValues[] values,
float acceptableOverheadRatio)
Create an ordinal map that uses the number of unique values of each
SortedDocValues instance as a weight. |
static MultiDocValues.OrdinalMap |
build(Object owner,
SortedSetDocValues[] values,
float acceptableOverheadRatio)
Create an ordinal map that uses the number of unique values of each
SortedSetDocValues instance as a weight. |
static MultiDocValues.OrdinalMap |
build(Object owner,
TermsEnum[] subs,
long[] weights,
float acceptableOverheadRatio)
Creates an ordinal map that allows mapping ords to/from a merged
space from
subs . |
Collection<Accountable> |
getChildResources()
Returns nested resources of this class.
|
int |
getFirstSegmentNumber(long globalOrd)
Given a global ordinal, returns the index of the first
segment that contains this term.
|
long |
getFirstSegmentOrd(long globalOrd)
Given global ordinal, returns the ordinal of the first segment which contains
this ordinal (the corresponding to the segment return
getFirstSegmentNumber(long) ). |
LongValues |
getGlobalOrds(int segmentIndex)
Given a segment number, return a
LongValues instance that maps
segment ordinals to global ordinals. |
long |
getValueCount()
Returns the total number of unique terms in global ord space.
|
long |
ramBytesUsed()
Return the memory usage of this object in bytes.

not be dense (e.g. can be FilteredTermsEnums}.weights
- a weight for each sub. This is ideally correlated with
