All Implemented Interfaces:

Cloneable

public final class ImportDeclaration
extends Node

This class represents a import declaration or an empty import declaration. Imports are optional for the CompilationUnit.

The ImportDeclaration is constructed following the syntax:

 
 ImportDeclaration ::= "import" ( "static" )? NameExpr ( "." "*" )? ";"
 
 

An enmpty import declaration is simply a semicolon among the import declarations.
