cases

public final Cases<T,X,TypedFunction<T,X>> cases()

Deprecated.

Overrides:

cases in class MatchingInstance<T,X>

whenIterable

public final IterableCase<X> whenIterable()

Deprecated.

Create a builder for matching on the disaggregated elements of a collection. Allows matching by type, value, JDK 8 Predicate, or Hamcrest Matcher per element

Returns:

Iterable / Collection based Pattern Matching Builder

whenFromStream

public final StreamCase whenFromStream()

Deprecated.

Create a builder that builds Pattern Matching Cases from Streams of data.

Returns:

Stream based Pattern Matching Builder

asUnwrappedFunction

public java.util.function.Function<T,X> asUnwrappedFunction()

Deprecated.

Overrides:

asUnwrappedFunction in class MatchingInstance<T,X>

Returns:

Pattern Matcher as function that will return the 'unwrapped' result when apply is called. i.e. Optional#get will be called.

asStreamFunction

public java.util.function.Function<T,java.util.stream.Stream<X>> asStreamFunction()

Deprecated.

Overrides:

asStreamFunction in class MatchingInstance<T,X>

Returns:

Pattern Matcher as a function that will return a Stream of results

apply

public java.util.Optional<X> apply(java.lang.Object t)

Deprecated.

Specified by:

apply in interface java.util.function.Function<T,java.util.Optional<X>>

Overrides:

apply in class MatchingInstance<T,X>

matchManyFromStream

public <R> java.util.stream.Stream<R> matchManyFromStream(java.util.stream.Stream s)

Deprecated.

Each input element can generated multiple matched values

Overrides:

matchManyFromStream in class MatchingInstance<T,X>

Parameters:

s - Stream of data to match against (input to matcher)

Returns:

Stream of values from matched cases

matchMany

public <R> java.util.stream.Stream<R> matchMany(java.lang.Object t)

Deprecated.

Overrides:

matchMany in class MatchingInstance<T,X>

Parameters:

Returns:

Stream of values from matched cases for the input

matchFromStream

public <R> java.util.stream.Stream<R> matchFromStream(java.util.stream.Stream s)

Deprecated.

Each input element can generated a single matched value

Overrides:

matchFromStream in class MatchingInstance<T,X>

Parameters:

s - Stream of data to match against (input to matcher)

Returns:

Stream of matched values, one case per input value can match

match

public java.util.Optional<X> match(java.lang.Object... t)

Deprecated.

Aggregates supplied objects into a List for matching against

 assertThat(Cases.of(Case.of((List<Integer> input) -> input.size()==3, input -> "hello"),
