Functions

childByName DynamicParseTree childByName(string name): Gets a child of this subtree by name.
childIndexByName size_t childIndexByName(string name): Returns the index of a child by name or size_t.max.
childName string childName(size_t index): Gets the name of child with index index.
childs inout(DynamicParseTree[]) childs(): Childs of this subtree. Will be empty for tokens.
content string content(): Text content for tokens.
hasChildWithName bool hasChildWithName(string name): Checks if this subtree has a child with some name.
isToken bool isToken(): Undocumented in source. Be warned that the author may not have intended to support it.
name string name(): Name for nonterminals.
setStartEnd void setStartEnd(typeof( ()()) start, typeof( ()()) end): Undocumented in source. Be warned that the author may not have intended to support it.
toString string toString(): Undocumented in source. Be warned that the author may not have intended to support it.

Variables

grammarInfo immutable(GrammarInfo)* grammarInfo;: Information about the grammar for this tree node.
location LocationRange location;: Location of this tree node in the source file.
nodeType NodeType nodeType;: Type of tree node. Should match the used subclass.
nonterminalID SymbolID nonterminalID;: ID of nonterminal for this tree starting at grammarInfo.startNonterminalID or SymbolID.max if not applicable. See grammarInfo.allNonterminals[nonterminalID - grammarInfo.startNonterminalID] for details about the nonterminal.
productionID ProductionID productionID;: ID of production for this tree starting at grammarInfo.startProductionID or ProductionID.max if not applicable. See grammarInfo.allProductions[productionID - grammarInfo.startProductionID] for details about the prodution.

Parameters

Location: Type of location in source file.
LocationRangeImpl: Template for determining how location ranges are stored (start + length, start + end, ...).
