# cp.rx.go.If

A Statement that will check if a resolvable matches a predicate, then executes other resolvables.

# Submodules

Constructors - API calls which return an object, typically one that offers API methods

Methods - API calls which can only be made on an object returned by a constructor


Signature	`cp.rx.go.If(value) -> If`
Type	Constructor
Description	Creates a new `If` `Statement` which will check the first result of `value`.
Parameters	value - a `resolvable` value that will be checked.
Returns	The `Statement` instance which will check if the `resolvable` matches the requirement.
Notes	By default, it will check if the value is `truthy` - not `nil` and not `false`. Other checks can be specified via the `If:Is/IsNot/Matches` methods. If the check passes, the `If:Then(...)` method is processed. If not, the `Otherwise` method can specify other `resolvables` to execute instead. Example: `lua</li><li>If(someObservable):Is(true):Then(</li><li> function() ... end</li><li>):Otherwise(</li><li> function() ... end</li><li>)</li><li>`

Signature	`cp.rx.go.If:Is(value) -> If.Is`

Signature	`cp.rx.go.If:IsNot(value) -> If.IsNot`
Type	Method
Description	Specifies the value to not match.
Parameters	value - The value to check for.
Returns	The IsNot Statement.Modifier.

Signature	`cp.rx.go.If:Matches(predicate) -> If.Matches`
Type	Method
Description	Specifies the predicate function that will check the `value` results.
Parameters	predicate - The function that will get called to determine if it has been found.
Returns	The Matches Statement.Modifier.
Notes	Example: `lua</li><li>If(someObservable):Matches(function(value) return value % 2 == 0 end):Then(doSomething())</li><li>`

Signature	`cp.rx.go.If:Then(...) -> If.Then`
Type	Method
Description	Call this to define what will happen if value resolves successfully.
Parameters	... - The list of `resolveable` values to process for the successful `If` result.
Returns	The `Then` `Statement.Modifier`.
Notes	The parameters can be any `resolvable` type. For example: `lua</li><li>If(anObservable)</li><li>:Then(function(aResult)</li><li> doSomethingWith(aResult, anotherResult)</li><li> return true</li><li>end)</li><li>`
