Example 1 with ROLE

use of com.vaticle.typedb.core.graph.common.Encoding.Vertex.Type.Root.ROLE in project grakn by graknlabs.

the class RelationTypeImpl method getRelates.

/**
 * Get the role type with a given {@code roleLabel} related by this relation type.
 *
 * First, look up the role type by the given label and it's scope: the relation label.
 * If the role type vertex do not exist, then call {@code role()} to get the inherited role types,
 * and see if the any of them has the {@code roleLabel} of interest.
 *
 * @param roleLabel the label of the role
 * @return the role type related in this relation
