public <X> X findCurrentFirst(Function<T, X> function)

Implements org.hibernate.internal.util.collections.Stack.findCurrentFirst.

Doc from org.hibernate.internal.util.collections.Stack.findCurrentFirst.

Find an element on the stack and return a value. The first non-null element returned from `action` stops the iteration and is returned from here

public <X, Y> X findCurrentFirstWithParameter(Y parameter, BiFunction<T, Y, X> biFunction)

Implements org.hibernate.internal.util.collections.Stack.findCurrentFirstWithParameter.

Doc from org.hibernate.internal.util.collections.Stack.findCurrentFirstWithParameter.

Runs a function on each couple defined as {Y,T} in which Y is fixed, and T is each instance of this stack. Not all Ts might be presented as the iteration is interrupted as soon as the first non-null value is returned by the (bi)function, which is then returned from this function.

Parameters
<X>
the return type of the function
<Y>
the type of the fixed parameter
parameter:Y

a parameter to be passed to the (bi)funtion

biFunction:BiFunction<T, Y, X>

a (bi)function taking as input parameter Y and each of the T from the current stack, and return type of X.

Returns:X

the first non-null result by the function, or null if no matches.
