Field Details

graphson

public static final String graphson

A value to supply to reader or writer to indicate the format to use. Using this shorthand will configure a default GraphSONReader or GraphSONWriter respectively,

See Also:

• Constant Field Values

gryo

public static final String gryo

A value to supply to reader or writer to indicate the format to use. Using this shorthand will configure a default GryoReader or GryoWriter respectively,

See Also:

• Constant Field Values

graphml

public static final String graphml

A value to supply to reader or writer to indicate the format to use. Using this shorthand will configure a default GraphMLReader or GraphMLWriter respectively,

See Also:

• Constant Field Values

reader

public static final String reader

The specific GraphReader instance to use, the name of the fully qualified classname of such an instance or one of graphson, gryo or graphml. If this value is not specified then GraphTraversalSource.io(String) will attempt to construct a default GraphReader based on the file extension provided to it.

writer

public static final String writer

The specific GraphWriter instance to use, the name of the fully qualified classname of such an instance or one of graphson, gryo or graphml. If this value is not specified then GraphTraversalSource.io(String) will attempt to construct a default GraphWriter based on the file extension provided to it.

registry

public static final String registry

A key that identifies the fully qualified class names of IoRegistry instances to use. May be specified multiple times (i.e. once for each registry) using the GraphTraversal.with(String, Object) modulator.
