Example 87 with NewIndexDescriptor

use of org.neo4j.kernel.api.schema_new.index.NewIndexDescriptor in project neo4j by neo4j.

the class NodeGetUniqueFromIndexSeekIT method shouldFindMatchingNode.

// Ensure that if that method is called again with the same argument from some other transaction,
// that transaction blocks until this transaction has finished
//
// [X] must return node from the unique index with the given property
// [X] must return NO_SUCH_NODE if it is not in the index for the given property
//
// must block other transactions that try to call it with the same arguments
