Constructors

KeyValueStructureLineContext(ParserRuleContext | undefined, number)

Properties

ruleIndex

Inherited Properties

altNumber

Set the outer alternative number for this context node. Default implementation does nothing to avoid backing field overhead for trees that don't need it. Create a subclass of ParserRuleContext with backing field and set option contextSuperClass. @since 4.5.3

childCount
children

If we are debugging or building a parse tree for a visitor, we need to track all of the tokens and rule invocations associated with this rule's context. This is empty for parsing w/o tree constr. operation because we don't the need to track the details about how we parse this rule.

exception

The exception that forced this rule to return. If the rule successfully completed, this is undefined.

invokingState
isEmpty

A context is empty if there is no invoking state; meaning nobody called current context.

parent
payload
ruleContext
sourceInterval
start

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.

stop

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.

text

Return the combined text of all child nodes. This method only considers tokens which have been added to the parse tree. Since tokens on hidden channels (e.g. whitespace or comments) are not added to the parse trees, they will not appear in the output of this method.

Inherited Methods

addAnyChild<T>(T)

Add a parse tree node to this as a child. Works for internal and leaf nodes. Does not set parent link; other add methods must do that. Other addChild methods call this. We cannot set the parent pointer of the incoming node because the existing interfaces do not have a setParent() method and I don't want to break backward compatibility for this.

@since 4.7

addChild(RuleContext)
addChild(TerminalNode)

Add a token leaf node child and force its parent to be this node.

addChild(Token)

Add a child to this node based upon matchedToken. It creates a TerminalNodeImpl rather than using [Token)](xref:Parser%23createTerminalNode(ParserRuleContext%2C). I'm leaving this in for compatibility but the parser doesn't use this anymore.

addErrorNode(ErrorNode)

Add an error node child and force its parent to be this node.

addErrorNode(Token)

Add a child to this node based upon badToken. It creates a ErrorNode rather than using [Token)](xref:Parser%23createErrorNode(ParserRuleContext%2C). I'm leaving this in for compatibility but the parser doesn't use this anymore.

copyFrom(ParserRuleContext)

COPY a ctx (I'm deliberately not using copy constructor) to avoid confusion with creating node with parent. Does not copy children (except error leaves). This is used in the generated parser code to flip a generic XContext node for rule X to a YContext for alt label Y. In that sense, it is not really a generic copy function.

If we do an error sync() at start of a rule, we might add error nodes to the generic XContext so this function must copy those nodes to the YContext as well else they are lost!

depth()
emptyContext()
getChild(number)
getChild<T>(number, { })
getChildContext(RuleContext, number)
getRuleContext<T>(number, { })
getRuleContexts<T>({ })
getToken(number, number)
getTokens(number)
removeLastChild()

Used by enterOuterAlt to toss out a RuleContext previously added as we entered a rule. If we have # label, we will need to remove generic ruleContext object.

setParent(RuleContext)
toInfoString(Parser)

Used for rule context info debugging during parse-time, not so much for ATN debugging

toString()
toString(Recognizer<any, any> | undefined)
toString(Recognizer<any, any> | undefined, RuleContext | undefined)
toString(string[] | undefined)
toString(string[] | undefined, RuleContext | undefined)
toStringTree()
toStringTree(Parser)

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.

toStringTree(string[] | undefined)

Print out a whole tree, not just a node, in LISP format (root child1 .. childN). Print just a node if this is a leaf.
