Types

type Resolver

type Resolver struct {
	SymbolTables map[ast.Node]*SymbolTable
	// contains filtered or unexported fields
}

Resolver resolves symbols in a Java program. Each identifier is mapped to the ast.Node that defined it.

func NewResolver

func NewResolver(tree *ast.Tree) *Resolver

NewResolver returns a new Resolver based on an AST.

func (*Resolver) Resolve

func (r *Resolver) Resolve() map[ast.Node]ast.Node

Resolve maps symbols in the AST to the nodes that define them. For example, a field in an expression will be mapped to the field definition node.

type SymbolTable

type SymbolTable struct {
	Types   map[string]ast.Node   // <- interfaces, enums, classes, etc.
	Members map[string][]ast.Node // <- overloaded functions + fields with this name
}

SymbolTable describes what's in a container node, such as a class, enum, interface, method, etc.
