Example 1 with NodePropertyConstraint

use of org.neo4j.kernel.api.constraints.NodePropertyConstraint in project neo4j by neo4j.

the class AlreadyConstrainedException method constructUserMessage.

private static String constructUserMessage(OperationContext context, TokenNameLookup tokenNameLookup, PropertyConstraint constraint) {
    switch(context) {
        case INDEX_CREATION:
            // is is safe to cast here because we only support indexes on nodes atm
