Method Detail

getAppArgs

Map<String,String> getAppArgs()

provide access to the expanded arguments of main(String[] args)

Returns:

- given arguments (if any)

getAppInfo

String getAppInfo()

print initial startup information

Returns:

- the message to print at application start

getApplicationDefaults

SystemDefault getApplicationDefaults()

access the application defaults. As the framework provides parts of application contexts, its essential to be able to change the settings of the placeholderConfigurer. So the SystemDefaults can't be coded as static class. This call will return an instance, that is provided by the framework, but can be overwritten by user applications.

Returns:

an instance that provides the system defaults

getApplicationName

String getApplicationName()

print the application name - may be localized. For identifying purpose consider using SystemDefault.applicationID

Returns:

- the applications name

getConfig

C getConfig()

access application starters configuration instance

Returns:

the configuration instance

setAppArgs

void setAppArgs(Map<String,String> appArgs)

set expanded arguments of main(String[] args)

Parameters:

appArgs - arguments from main expanded to key/value pairs

setConfig

void setConfig(C config)

set application starters configuration instance

Parameters:

config - the configuration instance

usage

void usage()

tell the user about the right usage
