In Processing Package

func NewPackage 

func NewPackage(pnc nc.NodeConverter, config *PackageConfig) (*Package, error)

When creating a new package for conversion, a Go file named after the package is generated by default. If SetCurFile is not called, all type conversions will be written to this default Go file.

func (*Package) CollectNameMapping 

func (p *Package) CollectNameMapping(originName, newName string, pnc nc.NodeConverter)

Collect the name mapping between origin name and pubname if in current package, it will be collected in public symbol table

func (*Package) Complete 

func (p *Package) Complete() error

Complete completes all incomplete type definitions, because some types may be implemented across multiple files.

func (*Package) Config 

func (p *Package) Config() *PackageConfig

func (*Package) GetUniqueName 

func (p *Package) GetUniqueName(node Node, pubName string) (_ string, changed bool)

GetUniqueName generates a unique public name for a given node using the provided name transformation method. It ensures the generated name doesn't conflict with existing names by adding a numeric suffix if needed.

Parameters:

  • node: The node containing the original name to be transformed
  • nameMethod: Function used to transform the original name (e.g., declName, constName)

Returns:

  • pubName: The generated unique public name
  • changed: Whether the generated name differs from the original name
