resolveShiftReduceConflict Object resolveShiftReduceConflict(Terminal terminal, Alternative alternative, size_t state): Calls for resolution of a shift/reduce parser conflict: The parser sees a conflict at state <code>state</code> whether to shift a <code>terminal</code> or reduce an <code>alternative</code> (the underlying grammar being understood). @param terminal @param alternative @param state @return <code>terminal</code> if the shift is favored; <code>alternative</code> if the reduce is favored; <code>null</code> if neither is accepted.
resolveReduceReduceConflict Object resolveReduceReduceConflict(Alternative alternative1, Alternative alternative2, Terminal terminal, size_t state): Calls for resolution of a reduce/reduce parser conflict: The parser sees a conflict at state <code>state</code> whether to reduce an <code>alternative1</code> or reduce an <code>alternative2</code> (the underlying grammar being understood). @param alternative1 @param alternative2 @param terminal Look-ahead @param state @return <code>alternative1</code> if reducing it is favored; <code>alternative2</code> if reducing it is favored; or <code>null</code> if neither is accepted.
noteHaltConflictOn void noteHaltConflictOn(Alternative alternative, size_t state): Notifies that there is a parser conflict at state <code>state</code> whether to halt or to reduce an <code>alternative</code> (the underlying grammar being understood). This indicates an ambiguity of the grammar. @param alternative @param state
