priorityAction

public abstract <A extends ActionDecl> A priorityAction(Class<A> type,
                                                        AbstractConflictDiagnosticReporter reporter,
                                                        ActionDeclFactory actionFactory,
                                                        Set<ActionEntry<A>> actions,
                                                        NodeDecl<?> node,
                                                        TerminalDecl terminal,
                                                        TerminalDecl eof)

Computes the priority action from a set

Type Parameters:

A - type of action from Regular/BranchTableActionDecl (cast can be safely performed to A from a type which implements both interfaces)

Parameters:

actions - the set actions

actionFactory - factory for actions

node - the node corresponding to the actions, for logging purpose

terminal - the terminal corresponding to the actions, for logging purpose. if the action set is a standard one, there is only one terminal in the set, if the action set is a branching action set, this set contains all conflicting branching terminals

eof - the end-of-input terminal

Returns:

the priority action or null in case of unresolved conflict.
