5.4.14 Specifying Labels for Vertices

The database and data access layer do not provide labels for vertices; however, you can treat the value of a designated vertex property as one or more labels. Such a transformation is relevant only to the in-memory analyst.

In the following example, a property "country" is specified in a call to setUseVertexPropertyValueAsLabel(), and the comma delimiter "," is specified in a call to setPropertyValueDelimiter(). These two together imply that values of the country vertex property will be treated as vertex labels separated by a comma. For example, if vertex X has a string value "US" for its country property, then its vertex label will be US; and if vertex Y has a string value "UK,CN", then it will have two labels: UK and CN.

GraphConfigBuilder.forPropertyGraph... 
   .setName("<your_graph_name>")
   ...
  .setUseVertexPropertyValueAsLabel("country")
  .setPropertyValueDelimiter(",")
  .setLoadVertexLabels(true)
  .build();
