Field Details

DEFAULT

public static final CelUtils.RegexEngine DEFAULT

The default engine when none is configured. Change this single value to flip the default for CelExecutor and the no-engine CelUtils.buildProgram(io.confluent.kafka.schemaregistry.rules.cel.CelUtils.ScriptType, java.lang.String, java.lang.Object, java.util.List<dev.cel.common.CelVarDecl>) overload. Does not affect CelValidator, which always uses RE2 for ReDoS safety on the hot serialize path.

Method Details

values

public static CelUtils.RegexEngine[] 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

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
