Class PropertiesCommandLine
- CommandLine
A CommandLine implementation using a java Properties instance, useful for
constructing a complex DefaultingCommandLine
Options are keyed from their property name and presence in the Properties
instance is taken as presence in the CommandLine. Argument values are taken
from the property value and are optionally separated using the separator
char, defined at construction time. Switch values can be specified using a
simple value of true
or false
; obviously this means
that Switches with Arguments are not supported by this implementation.
PropertiesCommandLine(Option root, Properties properties) - Creates a new PropertiesCommandLine using the specified root Option,
Properties instance.

PropertiesCommandLine(Option root, Properties properties, char separator) - Creates a new PropertiesCommandLine using the specified root Option,
Properties instance and value separator.
|
Option | getOption(String trigger) - Finds the Option with the specified trigger
|
Set | getOptionTriggers() - Retrieves a list of all Option triggers found in this CommandLine
|
List | getOptions() - Retrieves a list of all Options found in this CommandLine
|
Set | getProperties() - Retrieves the set of all property names associated with this CommandLine
|
String | getProperty(String property, String defaultValue) - Retrieves the value associated with the specified property
|
Boolean | getSwitch(Option option, Boolean defaultValue) - Retrieves the Boolean value associated with the specified Switch
|
List | getValues(Option option, List defaultValues) - Retrieves the Argument values associated with the specified Option
