/**
|
|
* The AstDeclaration and AstSymbol classes are API Extractor's equivalent of the compiler's
|
|
* ts.Declaration and ts.Symbol objects. They are created by the `AstSymbolTable` class.
|
|
*
|
|
* @remarks
|
|
* The AstSymbol represents the ts.Symbol information for an AstDeclaration. For example,
|
|
* if a method has 3 overloads, each overloaded signature will have its own AstDeclaration,
|
|
* but they will all share a common AstSymbol.
|
|
*
|
|
* For nested definitions, the AstSymbol has a unique parent (i.e. AstSymbol.rootAstSymbol),
|
|
* but the parent/children for each AstDeclaration may be different. Consider this example:
|
|
*
|
|
* ```ts
|
|
* export namespace N {
|
|
* export function f(): void { }
|
|
* }
|
|
*
|
|
* export interface N {
|
|
* g(): void;
|
|
* }
|
|
* ```
|
|
*
|
|
* Note how the parent/child relationships are different for the symbol tree versus
|
|
* the declaration tree, and the declaration tree has two roots:
|
|
*
|
|
* ```
|
|
* AstSymbol tree: AstDeclaration tree:
|
|
* - N - N (namespace)
|
|
* - f - f
|
|
* - g - N (interface)
|
|
* - g
|
|
* ```
