kandi X-RAY | cactoos Summary

cactoos is a Java library typically used in Artificial Intelligence, Computer Vision applications. cactoos has build file available, it has a Permissive License and it has high support. However cactoos has 32 bugs and it has 3 vulnerabilities. You can download it from GitHub, Maven.

ATTENTION: We're still in a very early alpha version, the API may and will change frequently. Please, use it at your own risk, until we release version 1.0. You can view our progress towards this release here. Cactoos is a collection of object-oriented Java primitives. Motivation. We are not happy with JDK, Guava, and Apache Commons because they are procedural and not object-oriented. They do their job, but mostly through static methods. Cactoos is suggesting to do almost exactly the same, but through objects. Principles. These are the design principles behind Cactoos.

Replace null with empty String decorator

Asked 2019-Mar-03 at 20:35

Is there in Cactoos framework some Text decorator (or maybe some other way), which replace null string with empty string? Like Strings.nullToEmpty function in Google Guava.

I have found NoNulls decorator, but I need just replacement without throwing exception.

So it must look like this:

QUESTION

Cactoos flatMap analogy

Asked 2019-Jan-31 at 17:14

Is there flatMap analogy in Cactoos library? I need exactly what flatMap can, but without streams:

The flatMap() operation has the effect of applying a one-to-many transformation to the elements of the stream, and then flattening the resulting elements into a new stream.

E.g. if I have some values in list, and each value has children items, and I want to get all items from each value, I can use flatMap:

You can use Joined, it is the equivalent of flattening an Iterable.

For example, you would write:

Asked 2017-Sep-06 at 06:53

While refactoring Rultor to use Cactoos instead of Guava, I’m having an issue with negative tests of GithubProfileTest and GithubProfileValidationTest.

After the refactor, the positive test cases pass for both mentioned test classes, but the negative test cases that expect a particular exception fail. The affected refactored code under test is GithubProfile.assets method and GithubProfile.asset method.

I refactored assets method to look like this:

ANSWER

Answered 2017-Sep-05 at 20:30

The reason is probably the conversion done in org.cactoos.func.UncheckedFunc while iterating to populate the map.

Since functional style programming usually does not play very well with exceptions, the API tries to avoid declaring checked exceptions. So you probably have to live with that.

For mapped iterable there is https://github.com/yegor256/cactoos/blob/master/src/main/java/org/cactoos/iterable/Mapped.java class. For function, there are plenty of them in the package https://github.com/yegor256/cactoos/tree/master/src/main/java/org/cactoos/func
