acceptPosition
protected SpanPositionCheckQuery.AcceptStatus acceptPosition(Spans spans) throws IOException
Description copied from class:SpanPositionCheckQuery
Implementing classes are required to return whether the current position is a match for the passed in "match"SpanQuery
. This is only called if the underlyingSpans.next()
for the match is successful- Specified by:
acceptPosition
in classSpanPositionCheckQuery
- Parameters:
spans
- TheSpans
instance, positioned at the spot to check- Returns:
- whether the match is accepted, rejected, or rejected and should move to the next doc.
- Throws:
IOException
- See Also:
Spans.next()
-
getStart
public int getStart()
- Returns:
- The minimum position permitted in a match
-
getEnd
public int getEnd()
- Returns:
- the maximum end position permitted in a match.
-
toString
public String toString(String field)
Description copied from class:Query
Prints a query to a string, withfield
assumed to be the default field and omitted.The representation used is one that is supposed to be readable by
QueryParser
. However, there are the following limitations:- If the query was created by the parser, the printed representation may not be exactly what was parsed. For example, characters that need to be escaped will be represented without the required backslash.
- Some of the more complicated queries (e.g. span queries) don't have a representation that can be parsed by QueryParser.
