Method Detail

convertException

public String convertException()

Converts most of the common instantiation exceptions from the class loader into an error message. Use for getting sensible error messages, of the causes that are associated with a FactoryException. The index in the messages starts from 0.

Returns:

the error message

convertException

public String convertException(int index)

Converts most of the common instantiation exceptions from the class loader into an error message. Use for getting sensible error messages, of the causes that are associated with a FactoryException. The index in the messages starts from 0.

Parameters:

index - the index to start from.

Returns:

the error message.

convertException

public static String convertException(String classname,
                                      Throwable e,
                                      int index)

Converts most of the common instantiation exceptions from the class loader into an error message. Use for getting sensible error messages, of the causes that are associated with a FactoryException.

Parameters:

classname - the class that was trying to be loaded or some other signifier.

e - the FactoryException that is thrown.

index - the index to start from.

Returns:

the error message.

getClassname

public String getClassname()

Returns the name of the class that was trying to be loaded when this error occured, or some other signifier like a module name.

Returns:

the name of the class.
