Constructor Detail

CloseElementEventNSImpl

public CloseElementEventNSImpl(String name)
                        throws NullPointerException

Creates a new close element event on the default namespace URI.

Parameters:

name - The local name of the element

Throws:

NullPointerException - If the name is null.

CloseElementEventNSImpl

public CloseElementEventNSImpl(String uri,
                               String name)
                        throws NullPointerException

Creates a new close element event.

Parameters:

uri - The namespace URI of the element

name - The local name of the element

Throws:

NullPointerException - if any of the argument is null.

CloseElementEventNSImpl

public CloseElementEventNSImpl(OpenElementEvent event)
                        throws NullPointerException

Creates a new close element event from the corresponding open element event.

Parameters:

event - The corresponding open element event.

Throws:

NullPointerException - If the name is null.

Method Detail

getName

public String getName()

Description copied from interface: CloseElementEvent

Returns the local name of the element.

Specified by:

getName in interface CloseElementEvent

Returns:

Returns the name.

getURI

public String getURI()

Description copied from interface: CloseElementEvent

Returns the namespace URI the element belongs to.

This method should return null if the implementation is not namespace aware.

Specified by:

getURI in interface CloseElementEvent

Returns:

Returns the namespace URI.

getOpenElement

public OpenElementEvent getOpenElement()

Returns the corresponding event element.

Specified by:

getOpenElement in interface CloseElementEvent

Returns:

The corresponding event element.

match

public boolean match(OpenElementEvent event)

Indicates whether the specified open element event matches this close element event.

This method first checks whether the open element event is the same as event returned by the CloseElementEvent.getOpenElement() method, if not it simply compares the name of the element and the namespace URI it belongs to.

Specified by:

match in interface CloseElementEvent

Parameters:

event - The open element event to test.

Returns:

true if there is a match; false otherwise.

hashCode

public int hashCode()

equals

public boolean equals(DiffXEvent e)

Returns true if the event is a close element event.

Specified by:

equals in interface DiffXEvent

Parameters:

e - The event to compare with this event.

Returns:

true if this event is equal to the specified event; false otherwise.

toString

public String toString()

Overrides:

toString in class Object

toXML

public void toXML(XMLWriter xml)
           throws IOException

Writes the XML representation of the implementing instance using the specified XMLWriter.

Specified by:

toXML in interface XMLWritable

Parameters:

xml - The XMLWriter to use.

Throws:

IOException - IF an I/O exception occurs whilst writing.

toXML

public StringBuffer toXML(StringBuffer xml)
                   throws NullPointerException

Appends the XML representation of the object of the implementing class.

Implementations must ensure that the returned string buffer is the same object as the specified string buffer.

Specified by:

toXML in interface XMLFormattable

Parameters:

xml - The string buffer to which the XML representation is appended to.

Returns:

The modified string buffer.

Throws:

NullPointerException - if the specified character sequence is null.

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()

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()

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)

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.
