Enum Constraint.ConstraintType

java.lang.Object
  java.lang.Enum<Constraint.ConstraintType>
      org.apache.stanbol.entityhub.servicesapi.query.Constraint.ConstraintType

All Implemented Interfaces:

Serializable, Comparable<Constraint.ConstraintType>

Enclosing class:

Constraint

public static enum Constraint.ConstraintType
extends Enum<Constraint.ConstraintType>

Defines the enumeration of available Constraints. TODO Maybe we need a more "extensible" way to define different constraints in future

Enum Constant Summary

range
Constraints a field to have a value within a range

similarity
Constraints a field to have a lexical value along with statistics to be able to compute a similarity metric (e.g.

text
Constraints a field to have a lexical value

value
Constraints the value and possible the dataType

Method Summary

Enum Constant Detail

value

public static final Constraint.ConstraintType value

Constraints the value and possible the dataType

range

public static final Constraint.ConstraintType range

Constraints a field to have a value within a range

text

public static final Constraint.ConstraintType text

Constraints a field to have a lexical value

similarity

public static final Constraint.ConstraintType similarity

Constraints a field to have a lexical value along with statistics to be able to compute a similarity metric (e.g. using the MoreLikeThis Solr handler)

Method Detail

values

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

Returns:

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

valueOf

public static Constraint.ConstraintType 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
