Method Detail

builder

public static CommandDetector.Builder builder()

search

public List<CommandDetector.Command> search(List<ArgumentResolution> resolvedArguments)

A stack is formed on the basis of the arguments provided by a command instruction. This stack is processed until there are no more usable elements. The foremost element is taken from the stack and checked to see if it matches the command to be searched for.

fullMatch

public List<ArgumentResolution> fullMatch(PredicateContext context)

Process and reduce the stack of arguments. Within the loop, which iterates over a stack of predicates, each argument from the stack is consumed and tested to see if the corresponding predicate is a match. Each consumed argument that matches is added to the list of arguments that will later form the suitable command. If a predicate is not optional and does not match, an empty list is returned. The method is then called again with a reduced argument stack until there are no more arguments on the stack. If a predicate can be applied multiple times to the argument stack, it is placed on the predicate stack again at the end of the loop.
