getFlags

public java.util.EnumSet<CommandFlagsRegistry.CommandFlag> getFlags(CommandArguments commandArguments)

Get the flags for a given command. Flags are looked up from a static registry based on the command arguments. This approach significantly reduces memory usage by sharing flag instances across all CommandObject instances.

For commands with subcommands (e.g., FUNCTION LOAD, ACL SETUSER), this method implements a hierarchical lookup strategy:

1. First, retrieve the parent command using CommandArguments.getCommand()
2. Check if this is a parent command (has subcommands in the registry)
3. If it is a parent command, attempt to get the child/subcommand by:
   • Extracting the second argument from the CommandArguments object
   • Matching this second argument against the child items of the parent command
4. Return the appropriate flags based on whether a child command was found or just use the parent command's flags

Specified by:

getFlags in interface CommandFlagsRegistry

Parameters:

commandArguments - the command arguments containing the command and its parameters

Returns:

EnumSet of CommandFlag for this command, or empty set if command has no flags
