		A base class to implement debugger plugins.
	</brief_description>
	<description>
		[EditorDebuggerPlugin] provides functions related to the editor side of the debugger.
		To interact with the debugger, an instance of this class must be added to the editor via [method EditorPlugin.add_debugger_plugin].
		Once added, the [method _setup_session] callback will be called for every [EditorDebuggerSession] available to the plugin, and when new ones are created (the sessions may be inactive during this stage).
		You can retrieve the available [EditorDebuggerSession]s via [method get_sessions] or get a specific one via [method get_session].

		    func _has_capture(prefix):
		        # Return true if you wish to handle message with this prefix.
		        return prefix == "my_plugin"

		    func _capture(message, data, session_id):
		        if message == "my_plugin:ping":
		            get_session(session_id).send_message("my_plugin:echo", data)

		    func _setup_session(session_id):
		        # Add a new tab in the debugger session UI containing a label.
		        var label = Label.new()
		        label.name = "Example plugin"
		        label.text = "Example plugin"
		        var session = get_session(session_id)

		        session.started.connect(func (): print("Session started"))
		        session.stopped.connect(func (): print("Session stopped"))

			<param index="0" name="message" type="String" />
			<param index="1" name="data" type="Array" />
			<param index="2" name="session_id" type="int" />
			<description>
				Override this method to process incoming messages. The [param session_id] is the ID of the [EditorDebuggerSession] that received the message (which you can retrieve via [method get_session]).
			</description>
		</method>
		<method name="_has_capture" qualifiers="virtual const">
			<return type="bool" />
			<param index="0" name="capture" type="String" />
			<description>
				Override this method to enable receiving messages from the debugger. If [param capture] is "my_message" then messages starting with "my_message:" will be passes to the [method _capture] method.
			</description>
		</method>
		<method name="_setup_session" qualifiers="virtual">
			<return type="void" />
			<param index="0" name="session_id" type="int" />
			<description>
				Override this method to be notified whenever a new [EditorDebuggerSession] is created (the session may be inactive during this stage).
			</description>
		</method>
		<method name="get_session">
			<return type="EditorDebuggerSession" />
			<param index="0" name="id" type="int" />
			<description>
				Returns the [EditorDebuggerSession] with the given [param id].
			</description>
		</method>
		<method name="get_sessions">
			<return type="Array" />
			<description>
				Returns an array of [EditorDebuggerSession] currently available to this debugger plugin.
				Note: Not sessions in the array may be inactive, check their state via [method EditorDebuggerSession.is_active]
