com.fr.third.jgroups.ViewId

所有已实现的接口:

Streamable, java.lang.Comparable<ViewId>

public class ViewId
extends java.lang.Object
implements java.lang.Comparable<ViewId>, Streamable

ViewIds are used for ordering views (each view has a ViewId and a list of members). Ordering between views is important for example in a virtual synchrony protocol where all views seen by a member have to be ordered.

构造器详细资料

ViewId

public ViewId()

ViewId

public ViewId(Address creator)

Creates a ViewID with the coordinator address and a Lamport timestamp of 0.

参数:

creator - the address of the member that issued this view

ViewId

public ViewId(Address creator,
      long id)

Creates a ViewID with the coordinator address and the given Lamport timestamp.

参数:

creator - - the address of the member that issued this view

id - - the Lamport timestamp of the view

方法详细资料

getCreator

public Address getCreator()

Returns the address of the member that issued this view

返回:

the Address of the the creator

getId

public long getId()

returns the lamport time of the view

返回:

the lamport time timestamp

toString

public java.lang.String toString()

覆盖:

toString 在类中 java.lang.Object

copy

public ViewId copy()

compareTo

public int compareTo(ViewId other)

Establishes an order between 2 ViewIds. The comparison is done on the IDs, if they are equal, we use the creator.

指定者:

compareTo 在接口中 java.lang.Comparable<ViewId>

返回:

0 for equality, value less than 0 if smaller, greater than 0 if greater.

compareToIDs

public int compareToIDs(ViewId other)

Establishes an order between 2 ViewIds. Note that we compare only on IDs !

返回:

0 for equality, value less than 0 if smaller, greater than 0 if greater.

equals

public boolean equals(java.lang.Object other)

覆盖:

equals 在类中 java.lang.Object

hashCode

public int hashCode()

覆盖:

hashCode 在类中 java.lang.Object

writeTo

public void writeTo(java.io.DataOutput out)
             throws java.lang.Exception

从接口复制的说明: Streamable

Write the entire state of the current object (including superclasses) to outstream. Note that the output stream must not be closed

指定者:

writeTo 在接口中 Streamable

抛出:

java.lang.Exception

readFrom

public void readFrom(java.io.DataInput in)
              throws java.lang.Exception

从接口复制的说明: Streamable

Read the state of the current object (including superclasses) from instream Note that the input stream must not be closed

指定者:

readFrom 在接口中 Streamable

抛出:

java.lang.Exception

serializedSize

public int serializedSize()
