Enum Trigger.TimeDomain

java.lang.Object

java.lang.Enum<Trigger.TimeDomain>

com.google.cloud.dataflow.sdk.transforms.windowing.Trigger.TimeDomain

All Implemented Interfaces:

java.io.Serializable, java.lang.Comparable<Trigger.TimeDomain>

Enclosing class:

Trigger<W extends BoundedWindow>

public static enum Trigger.TimeDomain
extends java.lang.Enum<Trigger.TimeDomain>

Triggers operate on both timestamps of elements that are being processed and the current (real-world) time as reported while processing. TimeDomain specifies which of these domains are applicable to a given operation.

Enum Constant Detail

EVENT_TIME

public static final Trigger.TimeDomain EVENT_TIME

The EVENT_TIME domain corresponds to the timestamps on the elemnts. Time advances on the system watermark advances.

PROCESSING_TIME

public static final Trigger.TimeDomain PROCESSING_TIME

The PROCESSING_TIME domain corresponds to the current to the current (system) time. This is advanced during exeuction of the Dataflow pipeline.

Method Detail

values

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

Returns:

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

valueOf

public static Trigger.TimeDomain 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
