MergeableCommand (hotswap-agent-core 2.0.0 API)

java.lang.Object
- org.hotswap.agent.command.MergeableCommand

All Implemented Interfaces:

Command

Direct Known Subclasses:

ReflectionCommand, ScheduledHotswapCommand, WatchEventCommand
```
public abstract class MergeableCommand
extends Object
implements Command
```
Command that can merge multiple commands into a single execution.
${Scheduler.schedule()} compares existing scheduled commands with equlas() method and if the command exists, it is replaced by new command and timer is restarted - effectively forgetting firs command. This implementation provides a way to get all merged commands and process them in the execution. It is also an interface to override merge method to provide custom behaviour.
For example - merge multiple MODIFY events into one, or if DELETE + CREATE events are scheduled, merge them into single MODIFY event.
