Uses of Function0 in org.opencastproject.util

Methods in org.opencastproject.util that return Function0

Modifier and Type	Method	Description
static Function0<InputStream>	IoSupport.fileInputStream(File a)	Create a function that creates a FileInputStream.

Methods in org.opencastproject.util with parameters of type Function0

Modifier and Type	Method	Description
<A> Option<A>	NeedleEye.apply(Function0<A> f)	Apply function f only if no other thread currently applies a function using this needle eye.
static <A, Err, B extends Closeable> Either<Err,A>	IoSupport.withResource(Function0<B> r, Function<Exception,Err> toErr, Function<B,A> f)	Handle a closeable resource inside f and ensure that r gets closed properly.
static <A, Err> Either<Err,A>	IoSupport.withStream(Function0<InputStream> s, Function<Exception,Err> toErr, Function<InputStream,A> f)	Deprecated. use IoSupport.withResource(org.opencastproject.util.data.Function0, org.opencastproject.util.data.Function, org.opencastproject.util.data.Function) instead

Uses of Function0 in org.opencastproject.util.data

Subclasses of Function0 in org.opencastproject.util.data

Modifier and Type	Class	Description
class	Effect0	Run a side effect.
static class	Effect0.X	Version of Effect0 that allows for throwing a checked exception.
static class	Function0.X<A>	Version of Function0 that allows for throwing a checked exception.

Methods in org.opencastproject.util.data that return Function0

Modifier and Type	Method	Description
Function0<B>	Function.curry(A a)	Currying.
static <A> Function0<A>	Option.error(String message)	Deprecated. use Option.orError(Throwable) or Option.orElse(Function0) instead since it saves the need for creating new objects just for the sake of type soundness.
Function0<B>	Function.o(Function0<? extends A> f)	Function composition.
<B> Function0<B>	Function0.then(Function<A,B> f)	Apply this function, then pass the result to f.
<B> Function0<B>	Function0.then(Function0<B> f)	Apply this function and ignore its result, then apply f.

Methods in org.opencastproject.util.data that return types with arguments of type Function0

Modifier and Type	Method	Description
Function<A,Function0<B>>	Function.curry()	Currying.

Methods in org.opencastproject.util.data with parameters of type Function0

Modifier and Type	Method	Description
abstract A	Option.getOrElse(Function0<A> none)	Get the contained value in case of being "some" or return the result of evaluating none otherwise.
Function0<B>	Function.o(Function0<? extends A> f)	Function composition.
Option<A>	Option.orElse(Function0<Option<A>> none)	Lazy version of Option.orElse(Option).
<B> Function0<B>	Function0.then(Function0<B> f)	Apply this function and ignore its result, then apply f.
