public final class CharactersEvent
extends CharactersEventBase

An event corresponds to the "characters" SAX event.

This event can be used to represent the text content of entire element. Typically, this would happen when there is no need to examine the text content of the node.

Constructor Detail

CharactersEvent

public CharactersEvent(CharSequence seq)
                throws NullPointerException
Creates a new characters event.

Parameters:
seq - The char sequence.
Throws:
NullPointerException - If the given String is null.
Method Detail

toString

public String toString()

Overrides:
toString in class Object

equals

public final boolean equals(Object o)
Invokes the DiffXEvent.equals(DiffXEvent) method if the specified object if not null and is an instance of DiffXEvent.

Overrides:
equals in class Object
Parameters:
o - The object to compare.
Returns:
true if the specified object is equal; false otherwise.

toXML

public String toXML()
Description copied from interface: XMLFormattable

Returns a xml representation of the object of the implementing class.

Most implementation should use the following code to ensure consistent data with the other toXML method:

return this.toXML(new StringBuffer()).toString();

Specified by:
toXML in interface XMLFormattable
Returns:
a XML representation of the object of the implementing class.

getWeight

public int getWeight()
Description copied from interface: DiffXEvent
Returns the weight of this event.

The default weight should be 1.

Specified by:
getWeight in interface DiffXEvent
Returns:
The weight of this event.

setWeight

public void setWeight(int weight)
Description copied from interface: DiffXEvent
Sets the weight of this event.

This method is intended for use by algorithms, optimisers and loaders in order to adjust the importance of an event.

Specified by:
setWeight in interface DiffXEvent
Parameters:
weight - The weight of this event.
