All Implemented Interfaces:

Logable, Commands, Serializable

Direct Known Subclasses:

TestCCI

public abstract class ConfigurableCommandsImpl2
extends AbstractCommandsImpl

Basic implementation of Commands that supports loading configurations. NOTE This does not actually run commands! It is a top-level class that delegates to its command implementations (such as for stores, keys). Therefore, you should not put code here that actually executes things. The contract of this is that it manages logging, loading configurations and instantiating the actual Commands implementations that do everything.

Method Detail

getConfigName

public String getConfigName()

setConfigName

public void setConfigName(String configName)

load

public void load(InputLine inputLine)
          throws Throwable

Description copied from class: AbstractCommandsImpl

Load resources before showing logos etc. This is typically called on your behalf in AbstractCommandsImpl.bootstrap(InputLine) amd should load resources needed. Note that an exception in this does not stop booting. This allows you to start a system with a missing configuration file (for instnace) and prompt for it.

See AbstractCommandsImpl.initialize() which is called after this and is charged with actually starting

Specified by:

load in class AbstractCommandsImpl

Throws:

Throwable

listConfigs

protected void listConfigs(InputLine inputLine)
                    throws Exception

Throws:

Exception

doListNames

protected List<String> doListNames(File target)
                            throws Exception

Figures out by file extension what to list. Override as needed. Default is .xml.

Parameters:

target -

Returns:

Throws:

Exception

listXMLConfigs

protected List<String> listXMLConfigs(File target)
                               throws Exception

Throws:

Exception

showLoadHelp

protected void showLoadHelp()

getEnvironment

public AbstractEnvironment getEnvironment()
                                   throws Exception

Throws:

Exception

setEnvironment

public void setEnvironment(AbstractEnvironment environment)

getComponentName

public abstract String getComponentName()

For the configuration. This is the tag name (e.g. "client" or "server") in the XML file. Note this is used by subclasses in other projects.

Returns:

getLoader

public abstract ConfigurationLoader<? extends AbstractEnvironment> getLoader()

setLoader

public abstract void setLoader(ConfigurationLoader<? extends AbstractEnvironment> loader)

initHelp

protected void initHelp()
                 throws Throwable

Overrides:

initHelp in class AbstractCommandsImpl

Throws:

Throwable

initialize

public void initialize()

Called at initialization to read and process the command line arguments. NOTE that this is not called in this class, but by inheritors.

Specified by:

initialize in class AbstractCommandsImpl

loadConfig

protected void loadConfig(String filename,
                          String configName)
                   throws Throwable

Loads the configuration and sets the filename and configuration given as the current ones.

Parameters:

filename -

configName -

Throws:

Throwable

figureOutLoader

protected abstract ConfigurationLoader<? extends AbstractEnvironment> figureOutLoader(String fileName,
                                                                                      String configName)

This is done so configurations can be loaded by inheritors.

Parameters:

fileName -

configName -

Returns:

Throws:

Throwable

getConfigFile

public String getConfigFile()

setConfigFile

public void setConfigFile(String configFile)

bootstrap

public InputLine bootstrap(InputLine args)
                    throws Throwable

Parses command line arguments. This is usually called after CLIDriver.bootstrap(String[]), which pulls off its startup options

Specified by:

bootstrap in interface Commands

Overrides:

bootstrap in class AbstractCommandsImpl

Parameters:

args -

Throws:

Exception

Throwable

useHelp

public abstract void useHelp()

use

public boolean use(InputLine inputLine)
            throws Throwable

Override this to invoke the specific components that make up your CLI.

Parameters:

inputLine -

Returns:

Throws:

Exception

Throwable

switchOrRun

protected boolean switchOrRun(InputLine inputLine,
                              CommonCommands2 commands)

Either switch to another component or (if there are arguments) simply run the single command and return. Note that each component has stored state, so these will be run with whatever is in that state. Requires use(InputLine) be overridden.

Parameters:

inputLine -

commands -

Returns:

setDriver

public void setDriver(CLIDriver driver)

Back reference to the driver for this class

Specified by:

setDriver in interface Commands

setDriver in class AbstractCommandsImpl

Parameters:

driver -
