ai.grakn.kb.internal.concept.AttributeTypeImpl<D>

Type Parameters:

D - The data type of this resource type. Supported Types include: String, Long, Double, and Boolean

All Implemented Interfaces:

AttributeType<D>, Concept, SchemaConcept, Type, ContainsTxCache, ConceptVertex, Comparable<Concept>

public class AttributeTypeImpl<D>
extends TypeImpl<AttributeType<D>,Attribute<D>>
implements AttributeType<D>

An ontological element which models and categorises the various Attribute in the graph.

This ontological element behaves similarly to Type when defining how it relates to other types. It has two additional functions to be aware of: 1. It has a AttributeType.DataType constraining the data types of the values it's instances may take. 2. Any of it's instances are unique to the type. For example if you have a AttributeType modelling month throughout the year there can only be one January.

Method Detail

get

public static <D> AttributeTypeImpl<D> get(VertexElement vertexElement)

create

public static <D> AttributeTypeImpl<D> create(VertexElement vertexElement,
                                              AttributeType<D> type,
                                              AttributeType.DataType<D> dataType)

sup

public AttributeType<D> sup(AttributeType<D> superType)

This method is overridden so that we can check that the regex of the new super type (if it has a regex) can be applied to all the existing instances.

Specified by:

sup in interface AttributeType<D>

Overrides:

sup in class SchemaConceptImpl<AttributeType<D>>

Parameters:

superType - This type's super type

Returns:

The Type itself

setRegex

public AttributeType<D> setRegex(String regex)

Specified by:

setRegex in interface AttributeType<D>

Parameters:

regex - The regular expression which instances of this resource must conform to.

Returns:

The AttributeType itself.

putAttribute

public Attribute<D> putAttribute(D value)

Specified by:

putAttribute in interface AttributeType<D>

getAttribute

public Attribute<D> getAttribute(D value)

Specified by:

getAttribute in interface AttributeType<D>

getDataType

public AttributeType.DataType<D> getDataType()

Specified by:

getDataType in interface AttributeType<D>

Returns:

The data type which instances of this resource must conform to.

getRegex

public String getRegex()

Specified by:

getRegex in interface AttributeType<D>

Returns:

The regular expression which instances of this resource must conform to.
