computeProperty

public <O> O computeProperty(InternalElement e)

getDataType

public Class<?> getDataType()

Description copied from interface: PropertyKey

Returns the data type for this property key. The values of all properties of this type must be an instance of this data type.

Specified by:

getDataType in interface PropertyKey

Returns:

Data type for this property key.

getCardinality

public Cardinality getCardinality()

Description copied from interface: PropertyKey

The Cardinality of this property key.

Specified by:

getCardinality in interface PropertyKey

Returns:

getName

public String getName()

Description copied from interface: Namifiable

Returns the unique name of this entity.

Specified by:

getName in interface Namifiable

Returns:

Name of this entity.

isPropertyKey

public boolean isPropertyKey()

Description copied from interface: RelationType

Checks if this relation type is a property key

Specified by:

isPropertyKey in interface RelationType

Returns:

true, if this relation type is a property key, else false.

See Also:

PropertyKey

isEdgeLabel

public boolean isEdgeLabel()

Description copied from interface: RelationType

Checks if this relation type is an edge label

Specified by:

isEdgeLabel in interface RelationType

Returns:

true, if this relation type is a edge label, else false.

See Also:

EdgeLabel

isHiddenType

public boolean isHiddenType()

Specified by:

isHiddenType in interface InternalRelationType

getMultiplicity

public Multiplicity getMultiplicity()

Specified by:

getMultiplicity in interface InternalRelationType

getID in interface TitanElement

Overrides:

getID in class EmptyVertex

Returns:

Unique long id

hasId

public boolean hasId()

Description copied from interface: TitanElement

Specified by:

hasId in interface TitanElement

Overrides:

hasId in class EmptyVertex

Returns:

true if this entity has been assigned a unique id, else false

See Also:

TitanElement.getID()

setID

public void setID(long id)

Specified by:

setID in interface InternalElement

Overrides:

setID in class EmptyVertex

toString

public String toString()

Overrides:

toString in class Object
