whatif relevant functions use Contracts internally by @skydoves in https://github.com/skydoves/WhatIf/pull/11
Since 1.1.1, every whatIf relevant functions use the Contracts as AT_MOST_ONCE internally.
It improving the variable initialization analysis in the presence of high-order functions:
val string: String
nullableString.whatIfNotNull {
string = it
// do something //
}

🎉 Released a new version 1.1.0! 🎉
whatIfFindFragment for FragmentActivity.
An expression for invoking [whatIf] when the [FragmentActivity] has an attached fragment [T]..whatIfFindFragment<MainTestFragment>(fragment_id) {
// do something
}
whatIfFindFragment<MainTestFragment>(MainTestFragment.TAG) {
// do something
}
whatIfFindParentInterface for finding a parent interface for Fragment.whatIfHasDeepLinkUri for invoking whatIf when the Activity's intent deep link URI is not null and not empty.WhatIfInlineOnly to internal.🎉 Released a new version 1.0.9! 🎉
WhatIfMap and deprecated whatIfLet.
The basic concept is the same as whatIf. An expression for invoking whatIf when the target object is not null.
It is useful when the receiver and the result should be different.val length = nullableString.whatIfMap(
whatIf = { it.length },
whatIfNot = {
log("$it, nullableString is null.")
-1
}
)
WhatIfAnd and WhatIfOr expressions for the nullable-Boolean iterables.whatIfNot and can be omitted the whatIfNot.val length = nullableString.whatIfMap(
default = -1
) {
log("$it, length can not over than 5.")
5
}
We can use some expressions for List, Map, and Set.
