ListenerDirective

public ListenerDirective(String name,
                         int priority,
                         URI uri,
                         String classname,

                         IllegalStateException

Creation of a new listener directive.

Parameters:

name - the listener name

priority - the listener priority

uri - the listener codebase

classname - optional classname of the plugin instantiation target

properties - supplimentary properties

Throws:

NullPointerException - if name or dependencies are null

IllegalStateException - if both classname and urn values are null

Method Detail

getName

public String getName()

Return the listener name.

Returns:

the listener name

getPriority

public int getPriority()

Return the listener priority.

Returns:

the priority value

getURI

public URI getURI()

Return the listener codebase uri.

Returns:

the urn

getURISpec

public String getURISpec()

Return the listener codebase uri as a string.

Returns:

the uri value

getClassname

public String getClassname()

Get the listener classname.

Returns:

the classname of the listener

compareTo

public int compareTo(Object other)
              throws ClassCastException

Compares this ListenerDirective object to another object. If the object is an ListenerDirective, this function behaves like compareTo(Integer). Otherwise, it throws a ClassCastException.

Specified by:

compareTo in interface Comparable

Parameters:

other - the Object to be compared.

Returns:

the value 0 if the argument is a ListenerDirective with a priority numerically equal to this ListenerDirective; a value less than 0 if the argument is a ListenerDirective numerically greater than this ListenerDirective; and a value greater than 0 if the argument is a ListenerDirective numerically less than this ListenerDirective.

Throws:

ClassCastException - if the argument is not an ListenerDirective.

See Also:

Comparable

equals

public boolean equals(Object other)

Compare this object with another for equality.

Overrides:

equals in class AbstractDirective

Parameters:

other - the other object

Returns:

true if equal

hashCode

public int hashCode()

Compute the hash value.

Overrides:

hashCode in class AbstractDirective

Returns:

the hashcode value
