All Implemented Interfaces:

java.io.Serializable, java.lang.Comparable<VertexIndex.Type>

Enclosing interface:

VertexIndex

public static enum VertexIndex.Type
extends java.lang.Enum<VertexIndex.Type>

DSE Graph supports the following types of indexes which are distinguished by their underlying index structures.

Enum Constant Detail

Materialized

public static final VertexIndex.Type Materialized

The index is build using materialized views. This type of index should only be used for highly selective indexes and equality condition retrievals. This is the fastest type of index

Secondary

public static final VertexIndex.Type Secondary

This index is build using secondary indexes. It only supports equality conditions. It is slower than Materialized but can index properties with lower selectivity.

Search

public static final VertexIndex.Type Search

This index uses Solr indexing. It supports a wide spectrum of query conditions and selectivities.

Method Detail

values

public static VertexIndex.Type[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (VertexIndex.Type c : VertexIndex.Type.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static VertexIndex.Type valueOf(java.lang.String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

java.lang.IllegalArgumentException - if this enum type has no constant with the specified name

java.lang.NullPointerException - if the argument is null
