JooseX.Attribute.Accessor.Combined - a role, combining setter and getter methods into one, ala perl
Class('Some.Class', {
has : {
attr : {
is : 'rwc',
init : 'some init value'
}
}
})
var instance = new Some.Class()
instance.attr() == 'some init value' // call to combined accessor as getter
instance.attr('some other value') // call to combined accessor as setter
instance.attr() == 'some other value' // attribute was changed
This role combines the getter and setter methods into one, having the same name as attribute itself.
Call this method without arguments will be directed to the actual getter call.
Call with some arguments provided will be directed to setter call.
Its safe to combine this role with Lazy and Trigger, but it should be applied after them.
To enable this role provide the trailing c
character in attribute's is
option:
has : {
attr : {
is : 'rwc',
init : 'some init value'
}
}
Alternatively, explicitly specify isCombined
option with some true
value:
has : {
attr : {
is : 'rw',
isCombined : true,
init : 'some init value'
}
}
