Methods

SetGraphProtocolVersion(GraphProtocol)

Sets the graph protocol version to use in graph queries. See GraphProtocolVersion.

Declaration

public GraphOptions SetGraphProtocolVersion(GraphProtocol version)

Parameters

Type	Name	Description
GraphProtocol	version

Returns

Type	Description
GraphOptions

SetLanguage(string)

Sets the graph language to use in graph queries. If you don't call this method, it defaults to DefaultLanguage.

Declaration

public GraphOptions SetLanguage(string language)

Parameters

Type	Name	Description
string	language

Returns

Type	Description
GraphOptions

SetName(string)

Sets the graph name to use in graph queries.

Declaration

public GraphOptions SetName(string name)

Parameters

Type	Name	Description
string	name

Returns

Type	Description
GraphOptions

SetReadConsistencyLevel(ConsistencyLevel)

Sets the consistency level for the read graph queries.

Declaration

public GraphOptions SetReadConsistencyLevel(ConsistencyLevel consistency)

Parameters

Type	Name	Description
ConsistencyLevel	consistency	The consistency level to use in read graph queries.

Returns

Type	Description

SetReadTimeoutMillis(int)

Sets the default per-host read timeout in milliseconds for all graph queries.

When setting a value of less than or equals to zero (System.Threading.Timeout.Infinite), it will use an infinite timeout.

Declaration

public GraphOptions SetReadTimeoutMillis(int timeout)

Parameters

string	source

Returns

Type	Description
GraphOptions

SetSourceAnalytics()

Sets the graph source to the server-defined analytic traversal source ('a')

Declaration

public GraphOptions SetSourceAnalytics()

Returns

Type	Description

SetWriteConsistencyLevel(ConsistencyLevel)

Sets the consistency level for the write graph queries.

Declaration

public GraphOptions SetWriteConsistencyLevel(ConsistencyLevel consistency)

Parameters

Type	Name	Description
ConsistencyLevel	consistency	The consistency level to use in write graph queries.

Returns

Type	Description
