Element Detail

name

public abstract String name

Name of the parameter.

description

public abstract String description

Description of the parameter.

Default:

""

min

public abstract double min

Minimum value used for number parameter.

Default:

0d/0d

max

public abstract double max

Maximum value used for number parameter.

Default:

0d/0d

type

public abstract Class<?> type

Class of the parameter.

Default:

java.lang.Object.class

strings

public abstract String[] strings

For String parameters, this allows to define a restricted set of values for the parameter.

Default:

{}

beforeSet

public abstract String beforeSet

Defines name of a function to call before setting the value of the parameter. If argument count of the function is zero, then the function will not receive argument. Else, if one argument is needed, the function will receive the value of parameter, if two arguments are needed, the function will receive the name of the parameter as a String and the value.

Default:

""

afterSet

public abstract String afterSet

Defines name of a function to call after setting the value of the parameter. If argument count of the function is zero, then the function will not receive argument. Else, if one argument is needed, the function will receive the value of parameter, if two arguments are needed, the function will receive the name of the parameter as a String and the value.

Default:

""

setter

public abstract String setter

Defines name of a function to call to set the value of the parameter. If one argument is needed, the function will receive the value of parameter, if two arguments are needed, the function will receive the name of the parameter as a String and the value.

Default:

""

priority

public abstract int priority

Defines the priority of the parameter. This is not yet implemented.

Default:

0

optional

public abstract boolean optional

Defines if the parameter is optional. This is used to throw a MissingParameterException during an initialization step to be sure that core parameters are present.

Default:

true
