Method Details

getSchema

public Schema getSchema()

Specified by:

getSchema in class AbstractLabel

getTopology

public Topology getTopology()

Specified by:

getTopology in class AbstractLabel

getInEdgeLabels

public Map<String,EdgeLabel> getInEdgeLabels()

getInEdgeRoles

public Map<String,EdgeRole> getInEdgeRoles()

getOutEdgeLabels

public Map<String,EdgeLabel> getOutEdgeLabels()

getOutEdgeRoles

public Map<String,EdgeRole> getOutEdgeRoles()

getOutEdgeLabel

public Optional<EdgeLabel> getOutEdgeLabel(String edgeLabelName)

Out EdgeLabels are always in the same schema as the 'this' VertexLabel' schema. So the edgeLabelName must not contain the schema prefix

Parameters:

edgeLabelName - The edge label's name

Returns:

Optionally the EdgeLabel

ensureEdgeLabelExist

public EdgeLabel ensureEdgeLabelExist(String edgeLabelName,
 VertexLabel inVertexLabel)

Ensures that the EdgeLabel exists. It will be created if it does not exists. "this" is the out VertexLabel and inVertexLabel is the inVertexLabel This method is equivalent to Schema.ensureEdgeLabelExist(String, VertexLabel, VertexLabel, Map)

Parameters:

edgeLabelName - The EdgeLabel's label's name.

inVertexLabel - The edge's in VertexLabel.

Returns:

The EdgeLabel.

ensureEdgeLabelExist

public EdgeLabel ensureEdgeLabelExist(String edgeLabelName,
 VertexLabel inVertexLabel,
 EdgeDefinition edgeDefinition)

ensureEdgeLabelExist

public EdgeLabel ensureEdgeLabelExist(String edgeLabelName,
 VertexLabel inVertexLabel,
 EdgeDefinition edgeDefinition,
 Map<String,PropertyDefinition> properties)

ensureEdgeLabelExist

public EdgeLabel ensureEdgeLabelExist(String edgeLabelName,
 VertexLabel inVertexLabel,
 Map<String,PropertyDefinition> properties)

Ensures that the EdgeLabel exists. It will be created if it does not exist. "this" is the out VertexLabel and inVertexLabel is the inVertexLabel This method is equivalent to Schema.ensureEdgeLabelExist(String, VertexLabel, VertexLabel, Map)

Parameters:

edgeLabelName - The EdgeLabel's label's name.

inVertexLabel - The edge's in VertexLabel.

properties - The EdgeLabel's properties

Returns:

The EdgeLabel

ensureEdgeLabelExist

public EdgeLabel ensureEdgeLabelExist(String edgeLabelName,
 VertexLabel inVertexLabel,
 Map<String,PropertyDefinition> properties,
 org.apache.commons.collections4.set.ListOrderedSet<String> identifiers)

Ensures that the EdgeLabel exists. It will be created if it does not exists. "this" is the out VertexLabel and inVertexLabel is the inVertexLabel This method is equivalent to Schema.ensureEdgeLabelExist(String, VertexLabel, VertexLabel, Map, ListOrderedSet)

Parameters:

edgeLabelName - The EdgeLabel's label's name.

inVertexLabel - The edge's in VertexLabel.

properties - The EdgeLabel's properties.

identifiers - The EdgeLabel's identifiers.

Returns:

The EdgeLabel

ensurePartitionedEdgeLabelExist

public EdgeLabel ensurePartitionedEdgeLabelExist(String edgeLabelName,
 VertexLabel inVertexLabel,
 Map<String,PropertyDefinition> properties,
 org.apache.commons.collections4.set.ListOrderedSet<String> identifiers,
 PartitionType partitionType,
 String partitionExpression)

ensurePropertiesExist

public void ensurePropertiesExist(Map<String,PropertyDefinition> columns)

ensureDistributed

public void ensureDistributed(int shardCount,
 PropertyColumn distributionPropertyColumn)

toString

public String toString()

Overrides:

toString in class Object

toJson

protected com.fasterxml.jackson.databind.JsonNode toJson()

toNotifyJson

protected Optional<com.fasterxml.jackson.databind.JsonNode> toNotifyJson()

hashCode

public int hashCode()

Overrides:

hashCode in class Object

equals

public boolean equals(Object other)

Overrides:

equals in class AbstractLabel

validateTopology

public List<Topology.TopologyValidationError> validateTopology(DatabaseMetaData metadata)
                                                        throws SQLException

Specified by:

validateTopology in class AbstractLabel

Throws:

SQLException

getPrefix

public String getPrefix()

Specified by:

Description copied from interface: TopologyInf

remove the topology item

Parameters:
