BasicCodec

public BasicCodec()

方法详细信息

setInputFormat

public Format setInputFormat(Format input)

从接口 Codec 复制的描述

Sets the format of the data to be input to this codec.

指定者：

接口 Codec 中的 setInputFormat

参数：

input - The Format to be set.

返回：

The Format that was set, which might be the supported Format that most closely matches the one specified. Returns null if the specified Format is not supported and no reasonable match could be found.

setOutputFormat

public Format setOutputFormat(Format output)

从接口 Codec 复制的描述

Sets the format for the data this codec outputs.

指定者：

接口 Codec 中的 setOutputFormat

参数：

output - The Format to be set.

返回：

The Format that was set, which might be the Format that most closely matched the one specified. Returns null if the specified Format is not supported and no reasonable match could be found.

getInputFormat

protected Format getInputFormat()

getOutputFormat

protected Format getOutputFormat()

reset

public void reset()

从接口 PlugIn 复制的描述

Resets the state of the plug-in. The reset method is typically called if the end of media is reached or the media is repositioned.

指定者：

接口 PlugIn 中的 reset

open

public void open()
          throws ResourceUnavailableException

从接口 PlugIn 复制的描述

Opens the plug-in software or hardware component and acquires the resources that the plug-in needs to operate. All required input and/or output formats have to be set on the plug-in before open is called. Buffers should not be passed into the plug-in without first calling this method.

指定者：

接口 PlugIn 中的 open

抛出：

ResourceUnavailableException - If all of the required resources cannot be acquired.

close

public void close()

从接口 PlugIn 复制的描述

Closes the plug-in component and releases the resources it was using. No more data will be accepted by the plug-in after close is called. A closed plug-in can be reinstated by calling open again.

指定者：

接口 PlugIn 中的 close

getSupportedInputFormats

public Format[] getSupportedInputFormats()

从接口 Codec 复制的描述

Lists all of the input formats that this codec accepts.

指定者：

接口 Codec 中的 getSupportedInputFormats

返回：

An array that contains the supported input Formats.

protected boolean isEOM(Buffer inputBuffer)

propagateEOM

protected void propagateEOM(Buffer outputBuffer)

updateOutput

protected void updateOutput(Buffer outputBuffer,
                            Format format,
                            int length,
                            int offset)
