7.2 SDO_NFE.CLASSIFY_LINES_BY_SIDE
Format
SDO_NFE.CLASSIFY_LINES_BY_SIDE( model_id IN NUMBER, ll_rule_id IN NUMBER, lines IN NUMBER, lhs_indexes OUT DBMS_SQL,NUMBER_TABLE, rhs_indexes OUT DBMS_SQL,NUMBER_TABLE);
Description
Given a set of line features that match a connectivity Line-Line rule, this procedure classifies which lines lie on the left hand side of the rule and which ones on the right hand side.
Parameters
- model_id
-
ID of the NFE model.
- ll_rule_id
-
Connectivity Line-Line rule identifier.
- lines
-
Set of line features that meet the rule..
- lhs_indexes
-
Associative array where the indexes of the lines lying on the left hand side of the rule will be stored (in the form (index, index)).
- rhs_indexes
-
Associative array where the indexes of the lines lying on the right hand side of the rule will be stored.
Usage Notes
The specified rule must be registered in the specified model. You can register a connectivity rule in the model tables or through the Java API.
Examples
The following example first gets all the interacting groups that meet the rule with ID 1 and then classifies the lines by side. Left hand side lines are output in lhs_indexes while rhs_indexes contain the rule’s right hand side lines.
DECLARE model_id NUMBER := 1; ll_rule_id NUMBER := 1; lines SDO_INTERACT_LINE_FEAT_ARRAY; lhs_indexes dbms_sql.NUMBER_TABLE; rhs_indexes dbms_sql.NUMBER_TABLE; inter_grps SDO_INTERACTION_ARRAY; BEGIN -- Get the groups of interacting features that meet the L-L Rule inter_grps := sdo_nfe.get_interaction_groups( model_id, sdo_nfe.RULE_TYPE_LINE_LINE, ll_rule_id ); FOR i IN 1..inter_grps.count loop lines := inter_grps(i).lines; -- For each group, classify the lines by rule side. sdo_nfe.classify_lines_by_side( model_id, ll_rule_id, lines, lhs_indexes, rhs_indexes ); END loop; END;
