Enum Constant Detail

AUTO

public static final FilterStrategy AUTO

AUTO analyzes the filter expression and splits it up into sub-expressions executed by different strategies.

DB

public static final FilterStrategy DB

DB executes the filter expression in DB.

POST

public static final FilterStrategy POST

POST executes the filter expression in memory after loading the whole graph.

STREAM

public static final FilterStrategy STREAM

STREAM executes the filter expression in memory visiting vertices/edges. TODO how to describe it ?

Method Detail

valueOf

public static FilterStrategy 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

values

public static FilterStrategy[] 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 (FilterStrategy c : FilterStrategy.values())
    System.out.println(c);

Returns:

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