Interface IAutoSnappingPredicate<T>

All Known Implementing Classes:

CaptureIntervalAutoSnappingPredicate, ShakeAutoSnappingPredicate

public IAutoSnappingPredicate<T>

A single check to be evaluated during autosnapping

Method Detail

checkState

boolean checkState(@NotNull
                   T param)

Run this check.

Parameters:

param - typed param that this implementation might need. Default is Unit

Returns:

whether this predicate currently allows autosnap

Note some (bad) magic here:

to achieve ability to implement interface IAutoSnappingPredicate with param or without it - we do unchecked cast here.

If interface IAutoSnappingPredicate's implementation explicitly defines some type to use as param - this cast will fail if nothing provided:

For class Foo : IAutoSnappingPredicate { ... } call myFoo.okDetected() will fail, as it expects myFoo.okDetected(myClassInstance).

To have implementation that does not need param, just use Unit and pass no parameter:

class Bar : IAutoSnappingPredicate { ... }, and then myBar.okDetected()
