All Implemented Interfaces:

CommandHandler, InvocationHistory, ReplyTextBundleAware

public class RetrCommandHandler
extends AbstractStubDataCommandHandler
implements CommandHandler

CommandHandler for the RETR (Retrieve) command. Return the configured file contents on the data connection, along with two replies on the control connection: a reply code of 150 and another of 226. By default, return an empty file (i.e., a zero-length byte[]). You can customize the returned file contents by setting the fileContents property, specified either as a String or as a byte array.

Each invocation record stored by this CommandHandler includes the following data element key/values:

• PATHNAME_KEY ("pathname") - the pathname of the file submitted on the invocation (the first command parameter)

Method Detail

beforeProcessData

protected void beforeProcessData(Command command,
                                 Session session,
                                 InvocationRecord invocationRecord)
                          throws Exception

Description copied from class: AbstractStubDataCommandHandler

Perform any necessary logic before transferring data across the data connection. Do nothing by default. Subclasses should override to validate command parameters and store information in the InvocationRecord.

Overrides:

beforeProcessData in class AbstractStubDataCommandHandler

Parameters:

command - - the Command to be handled

session - - the session on which the Command was submitted

invocationRecord - - the InvocationRecord; CommandHandlers are expected to add handler-specific data to the InvocationRecord, as appropriate

Throws:

Exception

AbstractStubDataCommandHandler.beforeProcessData(org.mockftpserver.core.command.Command, org.mockftpserver.core.session.Session, org.mockftpserver.core.command.InvocationRecord)

processData

protected void processData(Command command,
                           Session session,
                           InvocationRecord invocationRecord)

Description copied from class: AbstractStubDataCommandHandler

Abstract method placeholder for subclass transfer of data across the data connection. Subclasses must override. The data connection is opened before this method and is closed after this method completes.

Specified by:

processData in class AbstractStubDataCommandHandler

Parameters:

command - - the Command to be handled

session - - the session on which the Command was submitted

invocationRecord - - the InvocationRecord; CommandHandlers are expected to add handler-specific data to the InvocationRecord, as appropriate

AbstractStubDataCommandHandler.processData(org.mockftpserver.core.command.Command, org.mockftpserver.core.session.Session, org.mockftpserver.core.command.InvocationRecord)

setFileContents

public void setFileContents(String fileContents)

Set the file contents to return from subsequent command invocations

Parameters:

fileContents - - the fileContents to set

Throws:

AssertFailedException - - if the fileContents is null

setFileContents

public void setFileContents(byte[] fileContents)

Set the file contents to return from subsequent command invocations

Parameters:

fileContents - - the file contents

Throws:

AssertFailedException - - if the fileContents is null
