bool | read/write |
$arguments
Whether arguments to the program are allowed, when this parameter is submitted. |
mixed | read/write |
$default
Default value if the parameter is submitted without value. If a parameter is eg. of type ezcConsoleInput::TYPE_STRING and therefore expects a value when being submitted, it may be submitted without a value and automatically get the default value specified here. |
bool | read/write |
$isHelpOption
Whether a parameter is a help option. If this flag is true, and the parameter is set, all options marked as mandatory may be skipped. |
string | read |
$long
Long name of the parameter without '--' (eg. 'file'). |
string | read/write |
$longhelp
Long help text. Usually displayed when showing parameter detailed help. |
bool | read/write |
$mandatory
Whether a parameter is mandatory to be set. If this flag is true, the parameter must be submitted whenever the program is run. |
bool | read/write |
$multiple
Is the submission of multiple instances of this parameters allowed? |
string | read |
$short
Short name of the parameter without '-' (eg. 'f'). |
string | read/write |
$shorthelp
Short help text. Usually displayed when showing parameter help overview. |
int | read/write |
$type
Value type of this parameter, default is ezcConsoleInput::TYPE_NONE. See ezcConsoleInput::TYPE_NONE, ezcConsoleInput::TYPE_INT and ezcConsoleInput::TYPE_STRING. |

protected array(string=>mixed) |
$properties
Container to hold the properties |
public mixed |
$value
= false
The value the parameter was assigned to when being submitted. Boolean false indicates the parameter was not submitted, boolean true means the parameter was submitted, but did not have a value. In any other case, this caries the submitted value. |

Returns if a given name if valid for use as a parameter name a parameter.
Checks if a given parameter name is generally valid for use. It checks a) that the name does not start with '-' or '--' and b) if it contains whitespaces. Note, that this method does not check any conflicts with already used parameter names.

$name |
string | The name to check. |
Create a new parameter struct.
Creates a new basic parameter struct with the base information "$short" (the short name of the parameter) and "$long" (the long version). You simply apply these parameters as strings (without '-' or '--'). So
will result in a parameter that can be accessed using
or
The newly created parameter contains only it's 2 names and each other attribute is set to it's default value. You can simply manipulate those attributes by accessing them directly.
Name | Type | Description |
---|---|---|
$short |
string | Short name of the parameter without '-' (eg. 'f'). |
$long |
string | Long name of the parameter without '--' (eg. 'file'). |
$type |
int | Value type of the parameter. One of ezcConsoleInput::TYPE_*. |
$default |
mixed | Default value the parameter holds if not submitted. |
$multiple |
bool | If the parameter may be submitted multiple times. |
$shorthelp |
string | Short help text. |
$longhelp |
string | Long help text. |
$dependencies |
array(ezcConsoleOptionRule) | Dependency rules. |
$exclusions |
array(ezcConsoleOptionRule) | Exclusion rules. |
$arguments |
bool | Whether supplying arguments is allowed when this parameter is set. |
$mandatory |
bool | Whether the parameter must be always submitted. |
$isHelpOption |
bool | Indicates that the given parameter is a help option. If a help option is set, all rule checking is skipped (dependency/exclusion/ mandatory). |

ezcConsoleInvalidOptionNameException |
If the option names start with a "-" sign or contain whitespaces. |
