Constructor Description

OrdinalMap(Object owner, TermsEnum[] subs)
Creates an ordinal map that allows mapping ords to/from a merged space from subs.

Method Summary

All Methods Instance Methods Concrete Methods
Modifier and Type	Method	Description
`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)`).
`long`	`getGlobalOrd(int segmentIndex, long segmentOrd)`	Given a segment number and segment ordinal, returns the corresponding global ordinal.
`long`	`getValueCount()`	Returns the total number of unique terms in global ord space.
`long`	`ramBytesUsed()`	Returns total byte size used by this ordinal map.

public OrdinalMap(Object owner,
                  TermsEnum[] subs)
           throws IOException
```
    Creates an ordinal map that allows mapping ords to/from a merged space from subs.
    
    Parameters:
    
    owner - a cache key
    
    subs - TermsEnums that support TermsEnum.ord(). They need not be dense (e.g. can be FilteredTermsEnums}.
    
    Throws:
    
    IOException - if an I/O error occurred.
