Enum Constant Detail

DISABLED

public static final ConfigurationPlugInSingleRowFunction.FilterOptimizable DISABLED

The engine does not consider the single-row function for optimizing evaluation: The function gets evaluated for each event possibly multiple times.

ENABLED

public static final ConfigurationPlugInSingleRowFunction.FilterOptimizable ENABLED

The engine considers the single-row function for optimizing evaluation: The function gets evaluated only once per event.

Method Detail

values

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

Returns:

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

valueOf

public static ConfigurationPlugInSingleRowFunction.FilterOptimizable 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
