Trait Implementations

impl<'input, Ctx: CustomRuleContext<'input>> Borrow<Ctx> for BaseParserRuleContext<'input, Ctx>

fn borrow(&self) -> &Ctx

Immutably borrows from an owned value.

impl<'input, Ctx: CustomRuleContext<'input>> BorrowMut<Ctx> for BaseParserRuleContext<'input, Ctx>

fn borrow_mut(&mut self) -> &mut Ctx

Mutably borrows from an owned value.

impl<'input, Ctx: CustomRuleContext<'input>> CustomRuleContext<'input> for BaseParserRuleContext<'input, Ctx>

type TF = Ctx::TF

type Ctx = Ctx::Ctx

fn get_rule_index(&self) -> usize

fn get_alt_number(&self) -> isize

fn set_alt_number(&self, _alt_number: isize)

impl<'input, Ctx: CustomRuleContext<'input>> Debug for BaseParserRuleContext<'input, Ctx>

default fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl<'input, Ctx: CustomRuleContext<'input>> Deref for BaseParserRuleContext<'input, Ctx>

type Target = Ctx

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl<'input, Ctx: CustomRuleContext<'input>> DerefMut for BaseParserRuleContext<'input, Ctx>

fn deref_mut(&mut self) -> &mut Self::Target

Mutably dereferences the value.

impl<'input, Ctx: CustomRuleContext<'input> + TidAble<'input>> ParseTree<'input> for BaseParserRuleContext<'input, Ctx>

fn get_source_interval(&self) -> Interval

Return an {@link Interval} indicating the index in the {@link TokenStream} of the first and last token associated with this subtree. If this node is a leaf, then the interval represents a single token and has interval i..i for token index i.

default fn get_text(&self) -> String

Return combined text of this AST node. To create resulting string it does traverse whole subtree, also it includes only tokens added to the parse tree

fn to_string_tree(
    &self,
    r: &dyn Recognizer<'input, TF = Self::TF, Node = Self::Ctx>
) -> String

Print out a whole tree, not just a node, in LISP format (root child1 .. childN). Print just a node if this is a leaf. We have to know the recognizer so we can get rule names.

fn set_exception(&self, _e: ANTLRError)

fn set_start(&self, t: Option<<Ctx::TF as TokenFactory<'input>>::Tok>)

fn start<'a>(&'a self) -> Ref<'a, <Ctx::TF as TokenFactory<'input>>::Inner> where
    'input: 'a, 

Get the initial token in this context. Note that the range from start to stop is inclusive, so for rules that do not consume anything (for example, zero length or error productions) this token may exceed stop.

fn start_mut<'a>(
    &'a self
) -> RefMut<'a, <Self::TF as TokenFactory<'input>>::Tok> where
    'input: 'a,

fn stop<'a>(&'a self) -> Ref<'a, <Ctx::TF as TokenFactory<'input>>::Inner> where
    'input: 'a, 

Get the final token in this context. Note that the range from start to stop is inclusive, so for rules that do not consume anything (for example, zero length or error productions) this token may precede start.

fn stop_mut<'a>(&'a self) -> RefMut<'a, <Self::TF as TokenFactory<'input>>::Tok> where
    'input: 'a,

fn set_parent(
    &self,
    parent: &Option<Rc<<Ctx::Ctx as ParserNodeType<'input>>::Type>>
)

fn is_empty(&self) -> bool

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
