Method Detail

name

public String name()

Description copied from interface: Namifiable

Returns the unique name of this entity.

Specified by:

name in interface Namifiable

Returns:

Name of this entity.

id

public Object id()

Description copied from interface: JanusGraphElement

Returns a unique identifier for this entity.

The unique identifier may only be set when the transaction in which entity is created commits. Some entities are never assigned a unique identifier if they depend on a parent entity.

JanusGraph allocates blocks of identifiers and automatically assigns identifiers to elements automatically be default. This behavior can be partially overridden by setting GraphDatabaseConfiguration.ALLOW_SETTING_VERTEX_ID

Specified by:

id in interface org.apache.tinkerpop.gremlin.structure.Element

Specified by:

id in interface Idfiable

Specified by:

id in interface JanusGraphElement

Overrides:

id in class EmptyVertex

Returns:

The unique identifier for this entity

See Also:

JanusGraphElement.hasId()

hasId

public boolean hasId()

Description copied from interface: JanusGraphElement

Checks whether this entity has a unique identifier.

Note that some entities may never be assigned an identifier and others will only be assigned an identifier at the end of a transaction.

Specified by:

hasId in interface JanusGraphElement

Overrides:

hasId in class EmptyVertex

Returns:

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

setId

public void setId(Object id)

Specified by:

setId in interface InternalElement

Overrides:

setId in class EmptyVertex

getConsistencyModifier

public ConsistencyModifier getConsistencyModifier()

Specified by:

getConsistencyModifier in interface InternalRelationType

isInvisibleType

public boolean isInvisibleType()

Specified by:

isInvisibleType in interface InternalRelationType
