示例1: bits
BitSet* ChainedFilter::bits( IndexReader* reader, int logic )
{
BitSet* bts = NULL;
Filter** filter = filters;
// see discussion at top of file
if( *filter ) {
BitSet* tmp = (*filter)->bits( reader );
if ( (*filter)->shouldDeleteBitSet(tmp) ) //if we are supposed to delete this BitSet, then
bts = tmp; //we can safely call it our own
else if ( tmp == NULL ){
int32_t len = reader->maxDoc();
bts = _CLNEW BitSet( len ); //bitset returned null, which means match _all_
for (int32_t i=0;i<len;i++ )
bts->set(i);
}else{
bts = tmp->clone(); //else it is probably cached, so we need to copy it before using it.
}
filter++;
}
else
bts = _CLNEW BitSet( reader->maxDoc() );
while( *filter ) {
doChain( bts, reader, logic, *filter );
filter++;
}
