Constructor Detail

XEventImpl

public XEventImpl()

Creates a new event.

XEventImpl

public XEventImpl(XID id)

Creates a new event with a given ID.

Parameters:

id - the id for this event

XEventImpl

public XEventImpl(XAttributeMap attributes)

Creates a new event.

Parameters:

attributes - Map of attribute for the event.

XEventImpl

public XEventImpl(XID id,
                  XAttributeMap attributes)

Creates a new event with the given id and attributed

Parameters:

id - the id for this event

attributes - Map of attribute for the event.

Method Detail

getAttributes

public XAttributeMap getAttributes()

Description copied from interface: XAttributable

Retrieves the attributes set for this element.

Specified by:

getAttributes in interface XAttributable

Returns:

A map of attributes.

setAttributes

public void setAttributes(XAttributeMap attributes)

Description copied from interface: XAttributable

Sets the map of attributes for this element.

Specified by:

setAttributes in interface XAttributable

Parameters:

attributes - A map of attributes.

hasAttributes

public boolean hasAttributes()

Description copied from interface: XAttributable

Checks for the existence of attributes. This method can be a more efficient way of checking for the existance of attributes than using XAttributable.getAttributes() in certain situations.

Specified by:

hasAttributes in interface XAttributable

Returns:

whether this element has any attributes

getExtensions

public java.util.Set<XExtension> getExtensions()

Description copied from interface: XAttributable

Retrieves the extensions used by this element, i.e. the extensions used by all attributes of this element, and the element itself.

Specified by:

getExtensions in interface XAttributable

Returns:

A set of extensions.

clone

public java.lang.Object clone()

Clones this event, i.e. creates a deep copy, but with a new ID, so equals does not hold between this and the clone

Specified by:

clone in interface XElement

Overrides:

clone in class java.lang.Object

Returns:

An identical clone.

equals

public boolean equals(java.lang.Object o)

Tests for equality of IDs

Overrides:

equals in class java.lang.Object

hashCode

public int hashCode()

Returns the hashCode of the id

Overrides:

hashCode in class java.lang.Object

getID

public XID getID()

Description copied from interface: XEvent

Returns the id of the event

Specified by:

getID in interface XEvent

Returns:

the ID of this event

setID

public void setID(XID id)

Sets the ID. Should only be used for deserialization purposes

Parameters:

id - the new id.

accept

public void accept(XVisitor visitor,
                   XTrace trace)

Specified by:

accept in interface XEvent
