Specified by:

dataType in interface PropertyKey

Returns:

Data type for this property key.

cardinality

public Cardinality cardinality()

Description copied from interface: PropertyKey

The Cardinality of this property key.

Specified by:

cardinality in interface PropertyKey

Returns:

isPropertyKey

public final 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.

PropertyKey

isEdgeLabel

public final 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.
