Method Detail

cardinality

EdgeLabel.Builder cardinality(Cardinality cardinality)

Sets the cardinality for this edge label. If the cardinality is set to Cardinality.Single then only a single edge of this label may exists between any pair of vertices in a given direction. If the cardinality is Cardinality.Multiple then multiple edges can exist. The default cardinality is Cardinality.Multiple.

Parameters:

cardinality - The cardinality of this edge label.

Returns:

This builder.

single

default EdgeLabel.Builder single()

Sets the cardinality for this edge label to single.

Returns:

This builder

cardinality(Cardinality)

multiple

default EdgeLabel.Builder multiple()

Sets the cardinality for this edge label to multiple (which is the default).

Returns:

This builder

cardinality(Cardinality)

ttl

EdgeLabel.Builder ttl(java.time.Duration ttl)

Parameters:

ttl - The time to live for the edge label. Once expired the edge will be automatically removed.

Returns:

This builder.

ifNotExists

EdgeLabel.Builder ifNotExists()

Returns:

if the edge label already exists then just return it.

add

EdgeLabel add()

Create and add the edge label to the schema.

Returns:

the added edge label.

addPropertyKeys

EdgeLabel.Builder addPropertyKeys(java.lang.String... propertyKeys)
