/// depend directly on the file format). Once we have elements, we visit them

/// and construct the corresponding Kernel [Node]s.
|
|

///
|
|

/// The main entry points are [convertSdk] and [convertSummaries], which
|

/// convert the SDK and input summaries, respectively.
|
|
||||||
///
|
|
||||||
/// Because we only need to convert summaries, we do not need to handle method
|

/// bodies. This lets us avoid the complexity of converting Analyzer AST nodes
|
|
||||||
/// (e.g. expressions, statements).
|
|
||||||
///
|

/// For constants we use Analyzer's constant evaluator compute the value from

/// the data in the summary, and then create the appropriate Kernel node to

/// When something refers to an element, we normally create the [Reference] but

/// leave its corresponding [NamedNode] empty until that element is visited and
|
|

/// creates the Kernel node. This takes care of cycles, and avoids recursing too
|
|
||||||
/// deeply as we convert elements.
|
|
||||||
///
|
|
||||||
/// Sometimes we need to convert an element eagerly (e.g. if we need to call
|
|
||||||
/// members on an [InterfaceType] or [Supertype], we need to create its [Class]
|
|
||||||
/// node). In that case we handle cycles in the visit method (e.g.
|
|
||||||
/// [visitClassElement]) by creating the node and linking it to its reference
|
|
||||||
/// before visiting anything else that might recurse.
|
|
||||||
///
|
|

/// Special care must be taken to make sure we link up all [Reference]s with

/// their corresponding [NamedNode]. If we don't do this [verifyReferences]
|

/// will throw an error. The fix is to figure out why we didn't visit the
|
|
||||||
/// element for that reference (often this is due to Analyzer's synthetic
|
|
||||||
/// fields/accessor elements; care must be taken to always reference the real
|
|

/// element).
