Gets whether the lexer action is position-dependent. Position-dependent
actions may have different semantics depending on the {@link CharStream}
index at the time the action is executed.
<p>Many lexer commands, including {@code type}, {@code skip}, and
{@code more}, do not check the input index during their execution.
Actions like this are position-independent, and may be stored more

@return {@code true} if the lexer action semantics can be affected by the
position of the input {@link CharStream} at the time it is executed;
otherwise, {@code false}.
