Constructor Details

ContextPropagatingDecorator

public ContextPropagatingDecorator(IStreamCommand command)

デコレータを作成

Parameters:

command - ラップするコマンド

ContextPropagatingDecorator

public ContextPropagatingDecorator(IStreamCommand command,
 String commandName)

デコレータを作成（カスタムコマンド名付き）

Parameters:

command - ラップするコマンド

commandName - ログ用のコマンド名

Method Details

execute

public void execute(InputStream inputStream,
 OutputStream outputStream)
             throws IOException

Description copied from interface: IStreamCommand

Executes the command on the provided input stream and writes the result to the output stream.

This method maintains backward compatibility for existing implementations. When called without ExecutionContext, a new context will be automatically created by the StreamConverter pipeline.

Specified by:

execute in interface IStreamCommand

Parameters:

inputStream - The input stream to read data from.

outputStream - The output stream to write data to.

Throws:

IOException - If an I/O error occurs during the execution of the command.

execute

public void execute(InputStream inputStream,
 OutputStream outputStream,
 ExecutionContext context)
             throws IOException

Description copied from interface: IStreamCommand

Executes the command with ExecutionContext support for enhanced traceability.

This is the primary execution method that supports MDC context propagation, execution tracking, and enhanced logging capabilities.

Specified by:

execute in interface IStreamCommand

Parameters:

inputStream - The input stream to read data from.

outputStream - The output stream to write data to.

context - The execution context for traceability and logging enhancement.

Throws:

IOException - If an I/O error occurs during the execution of the command.

getWrappedCommand

public IStreamCommand getWrappedCommand()

ラップされたコマンドを取得

Returns:

ラップされたコマンド

getCommandName

public String getCommandName()

コマンド名を取得

Returns:

コマンド名

toString

public String toString()

Overrides:

toString in class Object
