Enum Constant Detail

CLONE_PER_BUNDLE

public static final DoFnTester.CloningBehavior CLONE_PER_BUNDLE

Clone the DoFn and call DoFn.Setup every time a bundle starts; call DoFn.Teardown every time a bundle finishes.

CLONE_ONCE

public static final DoFnTester.CloningBehavior CLONE_ONCE

Clone the DoFn and call DoFn.Setup on the first access; call DoFn.Teardown only explicitly.

Method Detail

values

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

Returns:

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

valueOf

public static DoFnTester.CloningBehavior 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
