[−][src]Trait antlr_rust::rule_context::RuleContext

pub trait RuleContext<'input>: CustomRuleContext<'input> {
    pub fn get_invoking_state(&self) -> isize { ... }

    pub fn set_invoking_state(&self, _t: isize) { ... }

    pub fn is_empty(&self) -> bool { ... }

    pub fn get_parent_ctx(

}

Minimal rule context functionality required for parser to work properly

Provided methods

pub fn get_invoking_state(&self) -> isize[src]

Internal parser state

pub fn set_invoking_state(&self, _t: isize)[src]

Sets internal parser state

pub fn is_empty(&self) -> bool[src]

A context is empty if there is no invoking state; meaning nobody called current context. Which is usually true for the root of the syntax tree

pub fn get_parent_ctx(
    &self
) -> Option<Rc<<Self::Ctx as ParserNodeType<'input>>::Type>>[src]

Get parent context

pub fn set_parent(
    &self,
    _parent: &Option<Rc<<Self::Ctx as ParserNodeType<'input>>::Type>>
)[src]

Set parent context
