Lets suppose you have 2 Lists A and B, and you want to remove from B all the elements that you have in A the method in this case is List.removeAll(Collection c); #Example: public static void main(String[] args) { List<Integer> numbersA = new ArrayList<>(); List<Intege...

Reverse elements within a tuple colors = "red", "green", "blue" rev = colors[::-1] # rev: ("blue", "green", "red") colors = rev # colors: ("blue", "green", "red") Or using reversed (reversed gives an it...

def str = 'Single quoted string' assert str instanceof String

def str = "Double quoted string" assert str instanceof String

def param = 'string' def str = "Double quoted ${param}" assert str instanceof GString assert str == 'Double quoted string' The parameter is by default resolved eagerly, this means this applies: def param = 'string' def str = "Double quoted ${param}" param = 'another stri...

All functions to interact with coroutines are avaliable in the coroutine table. A new coroutine is created by using the coroutine.create function with a single argument: a function with the code to be executed: thread1 = coroutine.create(function() print("honk") end)...

Python 2 includes a cmp function which allows you to determine if one object is less than, equal to, or greater than another object. This function can be used to pick a choice out of a list based on one of those three options. Suppose you need to print 'greater than' if x > y, 'less than' if x &...

Elasticsearch uses a YAML (Yet Another Markup Language) configuration file that can be found inside the default Elasticsearch directory (RPM and DEB installs change this location amongst other things). You can set basic settings in config/elasticsearch.yml: # Change the cluster name. All nodes in ...

If you need to apply a setting dynamically after the cluster has already started, and it can actually be set dynamically, then you can set it using _cluster/settings API. Persistent settings are one of the two type of cluster-wide settings that can be applied. A persistent setting will survive a fu...

If you need to apply a setting dynamically after the cluster has already started, and it can actually be set dynamically, then you can set it using _cluster/settings API. Transient settings are one of the two type of cluster-wide settings that can be applied. A transient setting will not survive a ...

Index settings are those settings that apply to a single index. Such settings will start with index.. The exception to that rule is number_of_shards and number_of_replicas, which also exist in the form of index.number_of_shards and index.number_of_replicas. As the name suggests, index-level setting...

You can apply the same change shown in the Index Settings example to all existing indices with one request, or even a subset of them: PUT /*/_settings { "index": { "indexing.slowlog.threshold.index.warn": "1s", "search.slowlog.threshold": { ...
