OVertex - getEdges()

This method retrieves all connected edges to or from this vertex.

Retrieving Edges

In a Graph database, edges represent relationships between vertices. These relationships have a direction, leading from one vertex to another. Using this method, you can retrieve all edges that connect to this vertex or connect from this vertex.

Syntax

Edges in OrientDB have direction and class. In the case of direction, the edge is created pointing from one vertex to another. This direction is implemented as the ODirection class. Additionally, edges like all records have classes internal to the database, which are implemented as OClass instance. On the database they either belong to the E class, or a class that extends the E class.

The first method uses the E class, and thus retrieves all edges that connect to or from the vertex. The remaining methods allow you to define which database class of edges you want to retrieve.

// METHOD 1
Iterable<OEdge> OVertex().getEdges(ODirection dir)

// METHOD 2
Iterable<OEdge> OVertex().getEdges(ODirection dir, OClass... type)

// METHOD 3
Iterable<OEdge> OVertex().getEdges(ODirection dir), String... name

Return Value

This method returns an Iterable instance that contains a series of OEdge instances representing the connected edges.
