static boolean |
allExists(int doc,
FunctionValues[] values)
Helper utility for
FunctionValues |
static boolean |
allExists(int doc,
FunctionValues values1,
FunctionValues values2)
Equivalent to the
FunctionValues[] method with the same name, but optimized for
dealing with exactly 2 arguments. |
static boolean |
anyExists(int doc,
FunctionValues[] values)
Helper utility for
FunctionValues |
static boolean |
anyExists(int doc,
FunctionValues values1,
FunctionValues values2)
Equivalent to the
FunctionValues[] method with the same name, but optimized for
dealing with exactly 2 arguments. |
void |
createWeight(Map context,
IndexSearcher searcher)
Implementations should propagate createWeight to sub-ValueSources which can optionally store
weight info in the context.
