kandi X-RAY | immu Summary

immu is a Java library. immu has no bugs, it has no vulnerabilities, it has build file available, it has a Permissive License and it has low support. You can download it from GitHub.

Immu will generate a developer-friendly toString() implementation with the following structure:. Where propertyName is the name of the property. @null is a special value that designates that the property had a value of null. @0abcdefa is an 8-character, hex value of System.identityHashCode() of the object in question. @0abcdefa is the value for the property as well as the System.identityHashCode() of the object in question. The location information will not be present for primitive types (int, byte, ...). toString values are cached. They can be cleared by accessing the immu.Immutable#clear() method, but this is only recommended for memory-constrained platforms such as Android, and even then it may not be necessary (depending on how many objects you have).

QUESTION

R find top n results of column operation on aggregate operation per column over dataframe

Asked 2019-May-10 at 02:41

Say I have a dataframe called RaM that holds cumulative return values. In this case, they literally are just a single row of cumulative return values along with column headers, but I would like to apply the logic to not just single row dataframes.

Say I want to sort by the max cumulative return value of each column, or even the average, or the sum of each column.

So each column would be re-ordered so that the max cumulative returns for each column is compared and the highest return becomes the 1st column with the min being the last column

then say I want to derive either the top 10 (1st 10 columns after they are rearranged), or even the top 10%.

I know how to derive the column averages, but I don't know how to effectively do the remaining operations. There is an order function, but when I used it, it stripped my column names, which I need. I could easily then cut the 1st say 10 columns, but is there a way that preserves the names? I don't think I can easily extract the names from the unordered original dataframe and apply it with my sorted by aggregate dataframe. My goal is to extract the column names of the top n columns (in dataframe RaM) in terms of a column aggregate function over the entire dataframe.

something like

Here's one way using the first section of your sample data to illustrate. You can gather up all the columns so that we can do summary calculations more easily, calculate all the summaries by group that you want, and then sort with arrange. Here I ordered with the highest sums first, but you could do whatever order you wanted.

React Native Dynamic Styling

Asked 2018-Aug-13 at 13:01

I am creating s crypto app where I want to change background color to red when the price went down and green when Price went up and then after 2 seconds change the background back to normal using setTimeout.

I tried two different methods to at-least change the backgroundColor but on both the occasion i got the following error

You attempted to set the key backgroundColor with the value #ffe5e5 on an object that is meant to be immutable and has been frozen.

I asked the separate question for the same but for some reason, the response I received was not convincing.

Afterwords, i tried a different approach (the one which does not allow the use of StyleSheet) but I still got the same error.

I am putting my new code here (you can refer to my previous code from the question)

First I declared an object in a global scope like this

QUESTION

Deconstruct const pointer?

Asked 2018-May-09 at 14:33

It's probably very basic but I am stuck and simply don't know what the problem is.

The main code is predefined as a task. The goal is to use const as much as possible. The following constructor is just supposed to copy the literal string to the const m_data and that works fine but I am not able to free the memory - it always leaves 1 block. What am I missing?

Vulnerabilities

No vulnerabilities reported

Install immu

Add this to your build.gradle. Substitute apt for your favorite Gradle annotation processor plugin. Android's newer build tools support annotationProcessor instead of apt from android-apt. JDK 8 or newer is required for javac although the generated source code will be Java 1.5 compatible. But please, switch to the latest Java on your platform. Using Maven? Figure it out. :).
