SpyDroid源码分析系列3：SessionBuilder之方法分析

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~方法如下：

好，下面开始来各个击破。

~~~~~~~~~~~~~~~~~~~~

// Removes the default public constructor
private SessionBuilder() {}
//设置为私有函数，这样外界无法构造出一个SessionBuilder对象，只能通过getInstance对象。
//自定义检查点: 1 2 3

/**
* Returns a reference to the {@link SessionBuilder}.
* @return The reference to the {@link SessionBuilder}
*/
public final static SessionBuilder getInstance() 
{
if (sInstance == null) 
{
synchronized (SessionBuilder.class) 
{
if (sInstance == null) 
{
SessionBuilder.sInstance = new SessionBuilder();
}
}
}
return sInstance;
}
//获取一个真正的SessionBuilder对象
//自定义检查点: 1 2 3

public SessionBuilder setContext(Context context) 
{
mContext = context;
return this;
}
 public Context getContext() 
{
return mContext;
}
//设置mContext对象和获取mContext对象
//自定义检查点: 1 2 3

public SessionBuilder setDestination(InetAddress destination) 
{
mDestination = destination;
return this; 
}
/** Returns the destination ip address set with {@link #setDestination(InetAddress)}. */
public InetAddress getDestination() 
{
return mDestination;
}
//对于mDestination的setter和getter方法

~~~~~~~~~~

public SessionBuilder setOrigin(InetAddress origin) 
{
mOrigin = origin;
return this;
}
/** Returns the origin ip address set with {@link #setOrigin(InetAddress)}. */
public InetAddress getOrigin() 
{
return mOrigin;
}
//对于mOrigin的setter和getter方法
~~~~~~~~~~~

public SessionBuilder setVideoQuality(VideoQuality quality) 
{
mVideoQuality = VideoQuality.merge(quality, mVideoQuality);
return this;
}
/** Returns the VideoQuality set with {@link #setVideoQuality(VideoQuality)}. */
public VideoQuality getVideoQuality() 
{
return mVideoQuality;
}
//对于mVideoQuality的setter和getter方法

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

/** Sets the audio quality. */
public SessionBuilder setAudioQuality(AudioQuality quality) 
{
mAudioQuality = AudioQuality.merge(quality, mAudioQuality);
return this;
}
/** Returns the AudioQuality set with {@link #setAudioQuality(AudioQuality)}. */
public AudioQuality getAudioQuality() 
{
return mAudioQuality;
}
//对于mAudioQuality的setter和getter方法

~~~~~~~~~~

public SessionBuilder setAudioEncoder(int encoder) 
{
mAudioEncoder = encoder;
return this;
}
 public int getAudioEncoder() 
{
return mAudioEncoder;
}
//对于mAudioEncoder的setter和getter方法

~~~~~~~

public SessionBuilder setVideoEncoder(int encoder) 
{
mVideoEncoder = encoder;
return this;
}
 public int getVideoEncoder() 
{
return mVideoEncoder;
}
//设置mVideoEncoder的setter和getter方法

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

public SessionBuilder setCamera(int camera) 
{
mCamera = camera;
return this;
}
 public int getCamera() 
{
return mCamera;
}
//对mCamera的setter和getter方法

~~~~~~~~~~~~~~~~~~~~~~~~~~

public SessionBuilder setFlashEnabled(boolean enabled) 
{
mFlash = enabled;
return this;
}
 public boolean getFlashState() 
{
return mFlash;
}
//对mFlash的setter和getter方法

~~~~~~~~~~~~~~~~~~~~~~~~~~~

public SessionBuilder setTimeToLive(int ttl) 
{
mTimeToLive = ttl;
return this;
}
 public int getTimeToLive() 
{
return mTimeToLive;
}
//对mTimeToLive的setter和getter方法
//自定义检查点:1 2 3 

~~~~~~~~~~~~~~~~~~~~~~~~~~~~

public SessionBuilder setSurfaceHolder(SurfaceHolder surfaceHolder) 
{
mSurfaceHolder = surfaceHolder;
return this;
}
public SurfaceHolder getSurfaceHolder() 
{
return mSurfaceHolder;
}
//对mSurfaceHolder的setter和getter方法

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

public SessionBuilder clone() 
{
return new SessionBuilder()
.setDestination(mDestination)
.setOrigin(mOrigin)
.setSurfaceHolder(mSurfaceHolder)
.setVideoQuality(mVideoQuality)
.setVideoEncoder(mVideoEncoder)
.setFlashEnabled(mFlash)
.setCamera(mCamera)
.setTimeToLive(mTimeToLive)
.setAudioEncoder(mAudioEncoder)
.setAudioQuality(mAudioQuality)
.setContext(mContext);
}
//构造当前对象的一个复制品

~~~~~~~~~~~~~~~~~~~~~~~~~~

然后就剩下最后一个函数build:

由于这个函数涉及到别的类，所以等后面分析好了再回来看。
