Torello.HTML.ReplaceablesOverlappingException

All Implemented Interfaces:

java.io.Serializable

public class ReplaceablesOverlappingException
extends ReplaceableException

Thrown during a Replaceable HTML-Vector update operation when two consecutive Replaceable instances appear to point to overlapping indices within the Vector.

Class ReplaceNodes method r(Vector, Iterable, boolean) is currently the primary means offered for efficiently modifying an HTML-Vector. It is inside that method where this exception may be thrown by the standard features of Java HTML JAR Library.

The two methods below practice code re-use, and they are wrappers for the above mentioned method. However, since the Replaceable Iterable's are automatically built inside that method, unless there are unforseen errors in the Java-HTML JAR Library, these methods really should not cause this exception to throw.

• listLI(Vector, DotPair, ObjIntConsumer)
• tableTR(Vector, DotPair, ObjIntConsumer)

Field Detail

serialVersionUID

🡇 ⇈ ⮫

public static final long serialVersionUID

This fulfils the SerialVersion UID requirement for all classes that implement Java's interface java.io.Serializable. Using the Serializable Implementation offered by java is very easy, and can make saving program state when debugging a lot easier. It can also be used in place of more complicated systems like "hibernate" to store data as well.

Note that Java's java.lang.Exception and java.lang.Error classes implement the Serializable interface, and a warning-free build expects this field be defined here.

If this package is extended, it is up to the programmer/user to make sure not to leave this field null when using one of these constructors.

IMPORTANT: All this is really trying to explain is that, when debugging your code, if in the analysis of a particular Exception, that analysis causes another exception throw (NullPointerException) - BECAUSE THIS CONVENIENCE FIELD WAS LEFT NULL - would be an unnecessary source of headache.

Constructor Detail

ReplaceablesOverlappingException

🡅 🡇 ⇈ ⮫

public ReplaceablesOverlappingException(Replaceable r1,
                                        Replaceable r2)

Constructs a ReplaceablesOverlappingException with no detail message.

Parameters:

r1 - A reference to the first Replaceable which caused this exception to throw

This parameter should not be left null. If it were accidentally left null, this could force exception-handling code to to throw an exception itself - while checking exceptions! Note that checking the input to this constructor does occur, and if this parameter is passed a null value, an instance of Torello.Java.ExceptionCheckError will throw.

r2 - A reference to the second Replaceable which caused this exception to throw

This parameter should not be left null. If it were accidentally left null, this could force exception-handling code to to throw an exception itself - while checking exceptions! Note that checking the input to this constructor does occur, and if this parameter is passed a null value, an instance of Torello.Java.ExceptionCheckError will throw.

                                        Replaceable r2)

Constructs a ReplaceablesOverlappingException with the specified detail message.

Parameters:

message - the detail message.

r1 - A reference to the first Replaceable which caused this exception to throw

This parameter should not be left null. If it were accidentally left null, this could force exception-handling code to to throw an exception itself - while checking exceptions! Note that checking the input to this constructor does occur, and if this parameter is passed a null value, an instance of Torello.Java.ExceptionCheckError will throw.

r2 - A reference to the second Replaceable which caused this exception to throw

This parameter should not be left null. If it were accidentally left null, this could force exception-handling code to to throw an exception itself - while checking exceptions! Note that checking the input to this constructor does occur, and if this parameter is passed a null value, an instance of Torello.Java.ExceptionCheckError will throw.
