Enum Constant Summary

Enum Constants

Enum Constant and Description
CONFIGURED Causes the runtimeto follow the runtime-wide policy as configured for user-defined functions.
DISABLED The default, the result of a single-row function is always computed anew.
ENABLED Causes the runtimeto not actually invoke the single-row function and instead return a cached precomputed value when all parameters are constants or there are no parameters.

Enum Constant Detail

DISABLED

public static final ConfigurationCompilerPlugInSingleRowFunction.ValueCache DISABLED

The default, the result of a single-row function is always computed anew.

ENABLED

public static final ConfigurationCompilerPlugInSingleRowFunction.ValueCache ENABLED

Causes the runtimeto not actually invoke the single-row function and instead return a cached precomputed value when all parameters are constants or there are no parameters.

CONFIGURED

public static final ConfigurationCompilerPlugInSingleRowFunction.ValueCache CONFIGURED

Causes the runtimeto follow the runtime-wide policy as configured for user-defined functions.

Method Detail

values

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

Returns:

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

valueOf

public static ConfigurationCompilerPlugInSingleRowFunction.ValueCache 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
