Class epp.TypeNameTable

java.lang.Object
   |
   +----epp.TypeNameTable

public class TypeNameTable

extends Object

This class handles "type names" that are Trees in the form of "(name ...)". Types with structures, such as array types are not handled.

The conversion is conducted under the following rules.

• Built-in type names such as "int" and "char" are returned as is.
• Names including a ".", such as in "java.util.Hashtable" are already fully qualified names, so they are returned unchanged. No checking is done to confirm that the class actually exists.
• Simple names such as "Object" and "Tree" are converted to fully qualified names of the classes they express, according to the Java language specification. If a corresponding class is not found or cannot uniquely determine a class, a EppUserError will be thrown.

The instance of this table is stored in the dynamic variable :typeNameTable. However, you cannot use this table until you get into Phase2. (According to the Java language specification, conversion to a fully qualified name in Phase1 is impossible. This is because, the conversion is affected by what classes exist in the current package.

The conversion to fully qualified names is done by referencing the package declarations and import declarations of the processed files, classes defined in all the source files, and class names that can be accessed through CLASSPATH.

TypeNameTable(Tree)

Receives a tree of CompilationUnit as an argument and creates and returns a TypeNameTable.

doesClassExist(Tree)

Returns true if the class expressed by the fully qualified name actually exists and is accesible, and otherwise returns false.

isSamePackage(Tree)

Returns true if the package currently processed and the package that the fullName belongs match, and otherwise returns false.

nameToFullName(Tree)

Converts a type name of a Tree into a Tree that expresses a fully qualified name.

nameToFullNameSymbol(Tree)

Converts a type name of a Tree into a Symbol.

 public TypeNameTable(Tree tree)

Receives a tree of CompilationUnit as an argument and creates and returns a TypeNameTable.

 public Symbol nameToFullNameSymbol(Tree tree)

Converts a type name of a Tree into a Symbol.

 public Tree nameToFullName(Tree tree)

Converts a type name of a Tree into a Tree that expresses a fully qualified name.

 public boolean doesClassExist(Tree fullName)

Returns true if the class expressed by the fully qualified name actually exists and is accesible, and otherwise returns false. This method is called from nameToFullName and Type#resolveAmbiguousName.

 public boolean isSamePackage(Tree fullName)

Returns true if the package currently processed and the package that the fullName belongs match, and otherwise returns false.
