Field Detail

DEVICE_VIEW_SPECIAL_PROCESS_FUNCTIONS

public static final java.util.Set<java.lang.String> DEVICE_VIEW_SPECIAL_PROCESS_FUNCTIONS

Set of functions are mappable but DeviceView of them also need special process. Now there is no function satisfies this.

Method Detail

values

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

Returns:

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

valueOf

public static BuiltinTimeSeriesGeneratingFunction 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

getFunctionName

public java.lang.String getFunctionName()

getFunctionClass

public java.lang.Class<?> getFunctionClass()

getClassName

public java.lang.String getClassName()
