Reports redundant Stream
or Optional

or redundant sorted()
or distinct()
calls.
- By ID
Can be used to locate inspection in e.g. Qodana configuration files, where you can quickly enable or disable it, or adjust its settings.
RedundantStreamOptionalCall
Note that a mapping operation in code like streamOfIntegers.map(Integer::valueOf)
works as requireNonNull()
check: if the stream contains null
, it throws a NullPointerException
, thus it's not absolutely redundant. Disable the Report redundant boxing in Stream.map() option if you do not want such cases to be reported.
This inspection depends on the Java feature 'Stream and Optional API', which is available since Java 8.
Here you can find the description of settings available for the Redundant step in 'Stream' or 'Optional' call chain inspection, and the reference of their default values.
