Interface MemberInfo

All Known Subinterfaces:

All Known Implementing Classes:

public interface MemberInfo

An interface that provides information common to all kinds of class members. This includes data members (represented by FieldInfo) and methods and constructors (represented by MethodInfo). This can be used to describe both MethodGenerators that are used to generate code and pre-existing Java classes.

Method Summary

Methods

Modifier and Type	Method and Description
boolean	isAccessibleInContext(ClassInfo definingClass, ClassInfo accessClass) Returns true iff this member is accessible in the context defined by definingClass (the class containing the reference to the member) and accessClass (the type of the expression used to access this member).
int	modifiers() Return the modifiers on this member
ClassInfo	myClassInfo() Return the ClassInfo of the class that contains this member.
String	name() Return the name of this member.

Method Detail

myClassInfo

ClassInfo myClassInfo()

Return the ClassInfo of the class that contains this member.

modifiers

int modifiers()

Return the modifiers on this member

name

String name()

Return the name of this member.

isAccessibleInContext

boolean isAccessibleInContext(ClassInfo definingClass,
                            ClassInfo accessClass)

Returns true iff this member is accessible in the context defined by definingClass (the class containing the reference to the member) and accessClass (the type of the expression used to access this member). This works as follows:

• If modifiers() contains PUBLIC, the access is permitted.
• If modifiers() contains PRIVATE, the access is permitted iff myClassInfo().name() is the same as definingClass.name().
• If modifiers() contains PROTECTED, the access is permitted as follows:
  • If myClassInfo().pkgName() is the same as definingClass.pkgName(), the access is permitted.
  • Otherwise, the access is permitted iff definingClass is a subclass of myClassInfo(), and accessClass is a subclass of definingClass.
• Otherwise, the access is permitted iff myClassInfo().pkgName is the same as definingClass.pkgName().

Parameters:

definingClass - the ClassInfo of the class in which the access occurs.

accessClass - the ClassInfo of the class used to access the member.
