Enum Class SubstitutionStrategy

java.lang.Object

java.lang.Enum<SubstitutionStrategy>

org.aksw.jena_sparql_api.algebra.transform.SubstitutionStrategy

All Implemented Interfaces:

Serializable, Comparable<SubstitutionStrategy>, Constable

public enum SubstitutionStrategy
extends Enum<SubstitutionStrategy>

Substitution strategy for constants in SPARQL graph patterns. One of:

• RETAIN => do nothing
• SUBSTITUTE => substitute affected constant with a variable, but do NOT inject a filter to the constant
• SUSTITUTE_AND_FILTER => substitute affected constant with a variablbe and inject a filter statement that constraints the variable to the original value

SUBSTITUTE

public static final SubstitutionStrategy SUBSTITUTE

Apply substitution

SUBSTITUTE_AND_FILTER

public static final SubstitutionStrategy SUBSTITUTE_AND_FILTER

Substitute and constrain to the original value

Method Details

values

public static SubstitutionStrategy[] values()

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

Returns:

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

valueOf

public static SubstitutionStrategy valueOf(String name)

Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (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 class has no constant with the specified name

NullPointerException - if the argument is null
