Examples with Label com.vaticle.typedb.core.common.parameters.Label used on opensource projects

Example 1 with Label

use of com.vaticle.typedb.core.common.parameters.Label in project grakn by graknlabs.

the class TypeGraph method getType.

public TypeVertex getType(String label, @Nullable String scope) {
    assert storage.isOpen();
    String scopedLabel = scopedLabel(label, scope);
    try {
        if (!isReadOnly) {
            multiLabelLock.readLock().lock();
            singleLabelLocks.computeIfAbsent(scopedLabel, x -> newReadWriteLock()).readLock().lock();
        }
        TypeVertex vertex = typesByLabel.get(scopedLabel);
        if (vertex != null)
            return vertex;
        IndexIID.Type index = IndexIID.Type.Label.of(label, scope);
        ByteArray iid = storage.get(index);
        if (iid != null) {
            vertex = typesByIID.computeIfAbsent(VertexIID.Type.of(iid), i -> new TypeVertexImpl.Persisted(this, i, label, scope));
            typesByLabel.putIfAbsent(scopedLabel, vertex);
        }
        return vertex;
    } finally {
        if (!isReadOnly) {
            singleLabelLocks.get(scopedLabel).readLock().unlock();
            multiLabelLock.readLock().unlock();
        }
    }
}

Example 2 with Label

use of com.vaticle.typedb.core.common.parameters.Label in project grakn by graknlabs.

    Rule rule = logicCache.rule().getIfPresent(label);
    if (rule != null)
        return rule;
    RuleStructure structure = graphMgr.schema().rules().get(label);
    if (structure != null)
        return logicCache.rule().get(structure.label(), l -> Rule.of(this, structure));
