activateNextProcessImage

public static void activateNextProcessImage(OpenemsComponent component)

Calls Channel.nextProcessImage() for every Channel of the OpenemsComponent.

Parameters:

component - the OpenemsComponent

withValue

public static void withValue(OpenemsComponent component,
 ChannelId channelId,
 Object value)

Sets the value on a Component Channel and activates the Process Image.

This is useful to simulate a Channel value in a Unit test, as the value becomes directly available on the Channel.

Parameters:

component - the OpenemsComponent

channelId - the ChannelId

value - the new value

withValue

public static void withValue(Channel<?> channel,
 Object value)

Sets the value on a Channel and activates the Process Image.

This is useful to simulate a Channel value in a Unit test, as the value becomes directly available on the Channel.

Parameters:
