Method Detail

invoke

public void invoke()
            throws BaseException

Description copied from class: AbstractCommand

Invoke the command associated with this command object. Before invoke is called, the command object must be populated with all the information (parameters) needed to invoke the service via the command object's setters. Once invoke has been called, the object's getters are used to retrieve the results.

Specified by:

invoke in class AbstractCommand

Throws:

BaseException

setArgs

public void setArgs(CommandArg that)

Description copied from class: AbstractCommand

Update this Command object's arguments with those taken from the command arg passed in. This is in effect a bulk setter. This interface will be implemented by beans that have many more getters/setters to support their properties. The implementations of this method take 'that', and pull all the relevant properties into this.

Specified by:

setArgs in class AbstractCommand

Parameters:

that - Source for arguments

getArgs

public CommandArg getArgs()

Description copied from class: AbstractCommand

Get the argument set associated with this command.

Specified by:

getArgs in class AbstractCommand

Returns:

This objects arguments.

getVersion

public Version getVersion()

Description copied from class: AbstractCommand

Fetch the version of the command (entry point) associated with this command. This is similar to the 'invoke' entry point in that control is passed to the entry point object. In this case to the getVersion() method.

Note: This method does not return the version of the command.

Specified by:

getVersion in class AbstractCommand

Returns:

The version of the entry point.

getConfiguration

public Configuration getConfiguration()

Description copied from class: AbstractCommand

Fetch the configuration of the entry point associated with this command. This is similar to invoke in that control is passed to the entry point object, in this case to the getConfiguration method. Note: This method does not return the configuration of the command object.

Specified by:

getConfiguration in class AbstractCommand

Returns:

The entry point's configuration.

setConfiguration

public void setConfiguration(Configuration config)

Description copied from class: AbstractCommand

Update the configuration of the entry point associated with this command. This is similar to the invoke method in that control is pass to the entry point object, in this case to its setConfiguration method. Note: This method does not set the configuration of the command object.

Specified by:

setConfiguration in class AbstractCommand

Parameters:

config - Properties to replace the current configuration.

setServiceClass

public void setServiceClass(java.lang.String serviceClass)
                     throws java.lang.ClassNotFoundException,
                            java.lang.InstantiationException,
                            java.lang.IllegalAccessException

Throws:

java.lang.ClassNotFoundException

java.lang.InstantiationException

java.lang.IllegalAccessException

getServiceClass

public java.lang.String getServiceClass()

setInstance

public void setInstance(Service instance)

getInstance

public Service getInstance()
