public boolean handleMessage(String command,

Description copied from class: CopilotCommand

Called whenever there is a message from the browser. Implementations should check if the command is for them, handle it and return true if the command was handled.

Specified by:

handleMessage in class CopilotCommand

Parameters:

command - the command to handle

data - the data for the command

devToolsInterface - the devtools interface for the connection

Returns:

true if the command was handled, false otherwise

canBeParallelCommand

public boolean canBeParallelCommand(String command)

Description copied from class: CopilotCommand

Checks if given command can be handled asynchronously. If the handler can't be asynchronous at all, it can return false always. But if you want to handle one or more commands asynchronously, you should specify the exact command to prevent handling commands that are not part of the handler as asynchronous.

canBeParallelCommand in class CopilotCommand

Parameters:

command - the command to check

Returns:

true if the command can be handled by this command handler
