Implementation returns a new sorted array of locations of declarations of types that implement (or are implemented by) the type referred to at the given position.

IncomingCalls returns an array of CallHierarchyIncomingCall for a file and the position within the file.

IsGenerated gets and reads the file denoted by uri and reports whether it contains a "generated file" comment as described at https://golang.org/s/generatedcode.

KnownPackagePaths returns a new list of package paths of all known packages in the package graph that could potentially be imported by the given file.

MetadataQualifierForFile returns a metadata qualifier that chooses the best qualification of an imported package relative to the file f in package with metadata m.

NarrowestMetadataForFile returns metadata for the narrowest package (the one with the fewest files) that encloses the specified file.

NarrowestPackageForFile is a convenience function that selects the narrowest non-ITV package to which this file belongs, type-checks it in the requested mode (full or workspace), and returns it, along with the parse tree of that file.

NewSignature returns formatted signature for a types.Signature struct.

PrepareRename searches for a valid renaming at position pp.

References returns a list of all references (sorted with definitions before uses) to the object denoted by the identifier at the given file/position, searching the entire workspace.

Rename returns a map of TextEdits for each file modified when renaming a given identifier within a package and a boolean value of true for renaming package and false otherwise.
