Package org.apache.commons.cli
Class CommandLine
java.lang.Object
org.apache.commons.cli.CommandLine
- All Implemented Interfaces:
Serializable
Represents list of arguments parsed against a
Options descriptor.
It allows querying of a boolean hasOption(String opt), in addition to retrieving the
getOptionValue(String opt) for options requiring arguments.
Additionally, any left-over or unrecognized arguments, are available for further processing.

Method Details
-
builder
Creates a new builder.- Returns:
- a new builder.
- Since:
- 1.7.0
-
addArg
Adds left-over unrecognized option/argument.- Parameters:
arg- the unrecognized option/argument.
-
addOption
Adds an option to the command line. The values of the option are stored.- Parameters:
opt- the processed option.
-
getArgList
Gets any left-over non-recognized options and arguments- Returns:
- remaining items passed in but not parsed as a
List.
-
getArgs
Gets any left-over non-recognized options and arguments- Returns:
- remaining items passed in but not parsed as an array.
-
getOptionObject
Deprecated.due to System.err message. Instead use getParsedOptionValue(char)Gets theObjecttype of thisOption.- Parameters:
opt- the name of the option.- Returns:
- the type of opt.
-
getOptionObject
Deprecated.due to System.err message. Instead use getParsedOptionValue(String)Gets theObjecttype of thisOption.- Parameters:
opt- the name of the option.- Returns:
- the type of this
Option.
-
getOptionProperties
Gets the map of values associated to the option. This is convenient for options specifying Java properties like-Dparam1=value1 -Dparam2=value2. All odd numbered values are property keys and even numbered values are property values. If there are an odd number of values the last value is assumed to be a boolean flag and the value is "true".- Parameters:
option- name of the option.- Returns:
- The Properties mapped by the option, never
nulleven if the option doesn't exists. - Since:
- 1.5.0
-
getOptionProperties
Gets the map of values associated to the option. This is convenient for options specifying Java properties like-Dparam1=value1 -Dparam2=value2. The first argument of the option is the key, and the 2nd argument is the value. If the option has only one argument (-Dfoo) it is considered as a boolean flag and the value is"true".- Parameters:
opt- name of the option.- Returns:
- The Properties mapped by the option, never
nulleven if the option doesn't exists. - Since:
- 1.2
-
