public class BasicFilterModule
extends BasicModule

BasicFilterModule is a module which is not threaded and have one InputConnector and one OutputConnector. It receives data from its input connector, pass the data to the level 3 plugIn codec and put the result in the OutputConnector. BasicFilterModule can be either Push or Pull driven. The plugIn codec might be media decoder, media encoder, effect etc.

构造方法详细信息

BasicFilterModule

public BasicFilterModule(Codec c)

方法详细信息

doRealize

public boolean doRealize()

从类 BasicModule 复制的描述

This function performs the steps of realizing a module or a Player.

指定者：

接口 StateTransistor 中的 doRealize

覆盖：

类 BasicModule 中的 doRealize

返回：

true if successful.

doPrefetch

public boolean doPrefetch()

从类 BasicModule 复制的描述

This function performs the steps to prefetch a module or Player.

指定者：

接口 StateTransistor 中的 doPrefetch

覆盖：

类 BasicModule 中的 doPrefetch

返回：

true if successful.

doClose

public void doClose()

从类 BasicModule 复制的描述

This function performs the steps to close a module or Player.

指定者：

接口 StateTransistor 中的 doClose

覆盖：

类 BasicModule 中的 doClose

setFormat

public void setFormat(Connector c,
                      Format f)

从类 BasicModule 复制的描述

Selects a format for this Connector (the default is null). The setFormat() method is typically called by the Manager as part of the Connector connection method call. Typically the connector would delegate this call to its owning Module.

指定者：

接口 Module 中的 setFormat

覆盖：

类 BasicModule 中的 setFormat

setCodec

public boolean setCodec(java.lang.String codec)

sets the plugIn codec of this filter.

参数：

codec - the plugIn codec (should we specify Codec class or String)

返回：

true if successful

setCodec

public boolean setCodec(Codec codec)

getCodec

public Codec getCodec()

返回：

the plugIn codec of this filter, null if not yet set.

isThreaded

public boolean isThreaded()

从类 BasicModule 复制的描述

return if this module create threads (so it run on Safe protocol) like Rendering module or not (as a codec module).

覆盖：

类 BasicModule 中的 isThreaded

getControls

public java.lang.Object[] getControls()

从类 BasicModule 复制的描述

Return a list of module controls.

指定者：

接口 Controls 中的 getControls

覆盖：

类 BasicModule 中的 getControls

返回：

the collection of object controls

getControl

public java.lang.Object getControl(java.lang.String s)

从接口 Controls 复制的描述

Obtain the object that implements the specified Class or Interface The full class or interface name must be used.

If the control is not supported then null is returned.

指定者：

接口 Controls 中的 getControl

覆盖：

类 BasicModule 中的 getControl

返回：

the object that implements the control, or null.

setFramesBehind

protected void setFramesBehind(float framesBehind)

reinitCodec

protected boolean reinitCodec(Format input)

A new input format has been detected, we'll check if the existing codec can handle it. Otherwise, we'll try to re-create a new codec to handle it.

process

public void process()

从类 BasicModule 复制的描述

function which does the real processing.

 if canRun {
    for (all inputConnectors)
      ic.getValidBuffer()
    for (all outputConnectors)
      oc.getEmptyBuffer()
    
    for (all inputConnectors)
      ic.readReport()
    for (all outputConnectors)
      oc.writeReport()
 }
 

指定者：

类 BasicModule 中的 process
