5.5.3 Using Manual Indexes for Property Graph Data

Manual indexes support the definition of multiple indexes over the vertices and edges of a property graph. A manual index requires that you manually put, get, and remove elements from the index.

When describing a manual index over a property graph, use the following methods to add, remove, and manipulate a manual index:

• OraclePropertyGraph.createIndex(String name, Class elementClass, Parameter[] parameters): Creates a manual index with the specified name for all elements of type elementClass.

• OraclePropertyGraph.dropIndex(String name): Drops the given manual index.

• OraclePropertyGraph.getIndex(String name, Class elementClass): Gets an index instance of the given manual index for type elementClass.

• OraclePropertyGraph.getIndices(): Gets an array of index instances for all manual indexes created in the property graph.
