Field Detail

id

public java.lang.String id

The endpoint identifier.

Constructor Detail

Endpt

public Endpt()

Constructs an anonimous endpoint.
The probability of two endpoints created using this constructor being equal, is very small. The endpoint is created by combining the localhost, the current time, and Object.hashCode().

Endpt

public Endpt(java.lang.String name)

Constructs an endpoint using the given String.

Parameters:

name - The name to be used as endpoint identifier.

Method Detail

equals

public boolean equals(Endpt e)

Tests if the endpoint represented by the given Endpt is the same one represented by this Endpt.

Parameters:

e - the other Endpt

Returns:

true if this Endpt and the given Endpt represent the same endpoint, false otherwise

equals

public boolean equals(java.lang.Object o)

Redefines Object.equals().

Overrides:

equals in class java.lang.Object

Parameters:

o - The object to compare.

Returns:

Returns true if this and the given object represent the same endpoint.

toString

public java.lang.String toString()

Converts the endpoint to a String.

Overrides:

toString in class java.lang.Object

Returns:

a String of the endpoint.

hashCode

public int hashCode()

Redefines Object.hashCode().
The hashcode is equal to the identifier hashcode

Overrides:

hashCode in class java.lang.Object

Returns:

hashcode for this Endpt

push

public static void push(Endpt endpt,
                        Message message)

pop

public static Endpt pop(Message message)

peek

public static Endpt peek(Message message)

writeExternal

public void writeExternal(java.io.ObjectOutput out)
                   throws java.io.IOException

Specified by:

writeExternal in interface java.io.Externalizable

Throws:

java.io.IOException

readExternal

public void readExternal(java.io.ObjectInput in)
                  throws java.io.IOException,
                         java.lang.ClassNotFoundException

Specified by:

readExternal in interface java.io.Externalizable

Throws:
