Function ParseDataForExtendsClassCompletion

internal/completion/position.go:90–126

ParseDataForExtendsClassCompletion parses position context for a completion in the extends clause of a class declaration. It calls ParseAccessedExpressionForCompletion and then walks up the AST to find the enclosing ClassDeclaration.
