public enum Comparator
extends java.lang.Enum<Comparator>

A comparator to be used in conditions to form comparison predicates.

Comparison operators listed here can be used to compare Field or Row values with other Field or Row values, or with Select or QuantifiedSelect values.

The following flags indicate whether the comparator can be used as:

• a quantified comparison operator: supportsQuantifier(). Example: X = ANY (A, B, C)
• a subselect comparison operator: supportsSubselect(). Example: X = (SELECT A)

Method Detail

values

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

Returns:

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

valueOf

public static Comparator 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

toSQL

public java.lang.String toSQL()

A SQL rendition of this comparator.

toKeyword

public Keyword toKeyword()

A keyword rendition of this comparator.

supportsQuantifier

public boolean supportsQuantifier()

Whether this comparator supports quantifiers on the right-hand side.

supportsSubselect

public boolean supportsSubselect()

Whether this comparator supports subselects on the right-hand side.
