public enum ErrorType
extends Enum<ErrorType>

The kind of linkage error against a symbol reference.

Enum Constant Summary

Enum Constants

Enum Constant and Description
ABSTRACT_METHOD The referenced method is not implemented in the class but the class is declared to implement the method.
CLASS_NOT_FOUND The target class of the symbol reference is not found in the class path.
INACCESSIBLE_CLASS The target class of the symbol reference is inaccessible to the source class.
INACCESSIBLE_MEMBER The target member (method or field) is inaccessible to the source class.
INCOMPATIBLE_CLASS_CHANGE The referenced class or interface found in the class path is not binary-compatible with the source class.
SYMBOL_NOT_FOUND For a method or field reference, the symbol is not found in the target class.

Method Summary

Modifier and Type	Method and Description
String	getMessage(String subject) Returns a human-friendly message explaining the error of subject.
static ErrorType	valueOf(String name) Returns the enum constant of this type with the specified name.
static ErrorType[]	values() Returns an array containing the constants of this enum type, in the order they are declared.

Enum Constant Detail

CLASS_NOT_FOUND

public static final ErrorType CLASS_NOT_FOUND

The target class of the symbol reference is not found in the class path.

INCOMPATIBLE_CLASS_CHANGE

public static final ErrorType INCOMPATIBLE_CLASS_CHANGE

The referenced class or interface found in the class path is not binary-compatible with the source class.

An example case of breaking binary-compatibility is when a superclass changes a method to final and a subclass is still overriding the method. Another example is when there is a method call to an interface and the interface is changed to a class with the same name.

ABSTRACT_METHOD

public static final ErrorType ABSTRACT_METHOD

The referenced method is not implemented in the class but the class is declared to implement the method. Such unimplemented methods manifest as AbstractMethodError in runtime.

INACCESSIBLE_CLASS

public static final ErrorType INACCESSIBLE_CLASS

The target class of the symbol reference is inaccessible to the source class.

If the source class is in a different package, the class or one of its enclosing types is not public. If the source class is in the same package, the class or one of its enclosing types is private.

INACCESSIBLE_MEMBER

public static final ErrorType INACCESSIBLE_MEMBER

The target member (method or field) is inaccessible to the source class.

If the source class is in a different package, the member is not public. If the source is in the same package, the class is private. If the source is a subclass of the target class, the member is not protected or public.

SYMBOL_NOT_FOUND

public static final ErrorType SYMBOL_NOT_FOUND

For a method or field reference, the symbol is not found in the target class.

Method Detail

values

public static ErrorType[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (ErrorType c : ErrorType.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static ErrorType valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null

getMessage

public String getMessage(String subject)

Returns a human-friendly message explaining the error of subject.
