has

public QueryContainer.QueryBuilder has(String type,
                                       Object value)

Description copied from interface: BaseVertexQuery

Query only for edges or properties that have an incident property or unidirected edge matching the given value.

If type is a property key, then the query is restricted to edges or properties having an incident property matching this key-value pair. If type is an edge label, then it is expected that this label is unidirected (EdgeLabel.isUnidirected() and the query is restricted to edges or properties having an incident unidirectional edge pointing to the value which is expected to be a TitanVertex.

Specified by:

has in interface BaseVertexQuery<QueryContainer.QueryBuilder>

Overrides:

has in class BaseVertexCentricQueryBuilder<QueryContainer.QueryBuilder>

Parameters:

type - TitanType name

value - Value for the property of the given key to match, or vertex to point unidirectional edge to

Returns:

this query

hasNot

public QueryContainer.QueryBuilder hasNot(String key,
                                          Object value)

Description copied from interface: BaseVertexQuery

Identical to BaseVertexQuery.has(String, Object) but negates the condition, i.e. matches those edges or properties that DO NOT satisfy this property condition.

Specified by:

hasNot in interface BaseVertexQuery<QueryContainer.QueryBuilder>

Overrides:

hasNot in class BaseVertexCentricQueryBuilder<QueryContainer.QueryBuilder>

Returns:

has

public QueryContainer.QueryBuilder has(String key)

Overrides:

hasNot in class BaseVertexCentricQueryBuilder<QueryContainer.QueryBuilder>

Returns:

this query

has

public QueryContainer.QueryBuilder has(String key,
                                       TitanPredicate predicate,
                                       Object value)

Specified by:

Overrides:

interval

public <T extends Comparable<?>> QueryContainer.QueryBuilder interval(String key,
                                                                      T start,

Description copied from interface: BaseVertexQuery

Query for those edges or properties that have a property for the given key whose values lies in the interval by [start,end).

Specified by:

interval in interface BaseVertexQuery<QueryContainer.QueryBuilder>

Overrides:

interval in class BaseVertexCentricQueryBuilder<QueryContainer.QueryBuilder>

Parameters:
