Examples with SchemaRule org.neo4j.internal.schema.SchemaRule used on opensource projects

Example 21 with SchemaRule

use of org.neo4j.internal.schema.SchemaRule in project neo4j by neo4j.

the class TransactionRecordState method schemaRuleDelete.

void schemaRuleDelete(long ruleId, SchemaRule rule) {
    RecordProxy<SchemaRecord, SchemaRule> proxy = recordChangeSet.getSchemaRuleChanges().getOrLoad(ruleId, rule, cursorContext);
    SchemaRecord record = proxy.forReadingData();
    if (record.inUse()) {
        record = proxy.forChangingData();
        record.setInUse(false);
        getAndDeletePropertyChain(record);
    }
// Index schema rules may be deleted twice, if they were owned by a constraint; once for dropping the index, and then again as part of
// dropping the constraint. So we keep this method idempotent.
