Enum Constant Detail

TEXT

public static final RewriteAlgorithm TEXT

Query sql text is compared to stored materialized view definition sql texts.

CALCITE

public static final RewriteAlgorithm CALCITE

Use rewriting algorithm provided by Calcite.

Field Detail

ALL

public static final EnumSet<RewriteAlgorithm> ALL

ANY

public static final Predicate<Set<RewriteAlgorithm>> ANY

NON_CALCITE

public static final Predicate<Set<RewriteAlgorithm>> NON_CALCITE

Method Detail

values

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

Returns:

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

valueOf

public static RewriteAlgorithm 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
