Enum Constant Details

SERVICE

public static final TupleFunctionEvaluationMode SERVICE

Uses the base SAIL along with an embedded SERVICE to perform query evaluation. The SERVICE is used to evaluate extended query algebra nodes such as TupleFunctions. (Default).

NATIVE

public static final TupleFunctionEvaluationMode NATIVE

Assumes the base SAIL supports an extended query algebra (e.g. TupleFunctions) and use it to perform all query evaluation.

TRIPLE_SOURCE

public static final TupleFunctionEvaluationMode TRIPLE_SOURCE

Treats the base SAIL as a simple triple source and all the query evaluation is performed by this SAIL.

Method Details

values

public static TupleFunctionEvaluationMode[] values()

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

Returns:

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

valueOf

public static TupleFunctionEvaluationMode valueOf(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:

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

NullPointerException - if the argument is null
