For a application specific spacer you could use:

So, I was wrong posting the last answer. I found out, the libc binary contained something like __xstat and I called it.

Wrong! As the name would suggest, it was a kind of a private function, something intended to be an implementation detail, not a part of the API.

So I found another function with a normal name: statx. It does exactly what I need, it is well(-ish) documented here:

https://man7.org/linux/man-pages/man2/statx.2.html

Here's the structure and values: https://code.woboq.org/qt5/include/bits/statx.h.html https://code.woboq.org/userspace/glibc/io/fcntl.h.html

TL;DR - it works.

I figured out that -100 (AT_FDCWD) passed as dirfd parameter makes relative paths relative to the current working directory.

I also figured out that passing zeros as flags works (as equivalent to AT_STATX_SYNC_AS_STAT), and the function returns what it should for a regular local filesystem.

So here's the code:

solved using reduce and forEach

Inside the reduce function I'm running a forEach on the array of keys of the incomes object/attribute. For each key which is a date I'm checking if the accumulator of the reduce function contains an attribute for each date and creates if not. After creating the attribute I'm summing the value for the current date attribute.

The issue is that df_pt is a data.frame and it needs to be used as input in each of the looped element. So, wrap it with list so that it gets recycled as a single unit. When we loop over the data.frame, the column is a unit and this triggers the error Erro: Element 3 of .l must have length 1 or 30, not 3 as the number of columns is 3.

You might be able to apply something like this by taking a few measurements from the boxes you want to connect; offsetTop and clientHeight.

Update Added some logic for undrawn cards requirement.

While this doesn't fully simulate dynamic populating of cards, I made an update to show how to handle a scenario where only one card is drawn.

1. Click connect using the default values (1 and 5). This will show an open connector starting from box 1.
2. Click "Add box 5". This will add the missing box and update the connector.

The remaining work here is to create an event listener on scroll to check the list of connectors. From there you can check if both boxes appear or not in the DOM (see checkConnectors function). If they appear, then pass values to addConnector which will connect them fully.

You should wrap your Java service with callback in an effect using effectAsync:

Summary: we define two sketch functions f and g from entries to sets of “sketches” such that two entries e and e′ are similar if and only if f(e) ∩ g(e′) ≠ ∅. Then we can identify merges efficiently (see the algorithm at the end).

I’m actually going to define four sketch functions, f_os, f_addr, g_os, and g_addr, from which we construct

• f(e) = {(x, y) | x ∈ f_os(e), y ∈ f_addr(e)}
• g(e) = {(x, y) | x ∈ g_os(e), y ∈ g_addr(e)}.

f_os and g_os are the simpler of the four. f_os(e) includes

• (1, e.os), if e.os is known
• (2,), if e.os is known
• (3,), if e.os is unknown.

g_os(e) includes

• (1, e.os), if e.os is known
• (2,), if e.os is unknown
• (3,).

f_addr and g_addr are more complicated because there are prioritized attributes, and they can have multiple values. Nevertheless, the same trick can be made to work. f_addr(e) includes

• (1, h) for each h in e.hostname
• (2, m) for each m in e.mac, if e.hostname is nonempty
• (3, m) for each m in e.mac, if e.hostname is empty
• (4, i) for each i in e.ip, if e.hostname and e.mac are nonempty
• (5, i) for each i in e.ip, if e.hostname is empty and e.mac is nonempty
• (6, i) for each i in e.ip, if e.hostname is nonempty and e.mac is empty
• (7, i) for each i in e.ip, if e.hostname and e.mac are empty.

g_addr(e) includes

• (1, h) for each h in e.hostname
• (2, m) for each m in e.mac, if e.hostname is empty
• (3, m) for each m in e.mac
• (4, i) for each i in e.ip, if e.hostname is empty and e.mac is empty
• (5, i) for each i in e.ip, if e.mac is empty
• (6, i) for each i in e.ip, if e.hostname is empty
• (7, i) for each i in e.ip.

The rest of the algorithm is as follows.

• Initialize a defaultdict(list) mapping a sketch to a list of entry identifiers.

• For each entry, for each of the entry’s f-sketches, add the entry’s identifier to the appropriate list in the defaultdict.

• Initialize a set of edges.

• For each entry, for each of the entry’s g-sketches, look up the g-sketch in the defaultdict and add an edge from the entry’s identifiers to each of the other identifiers in the list.

Now that we have a set of edges, we run into the problem that @btilly noted. My first instinct as a computer scientist is to find connected components, but of course, merging two entries may cause some incident edges to disappear. Instead you can use the edges as candidates for merging, and repeat until the algorithm above returns no edges.

I haven't looked at the GCC code, so I'm just doing some guesswork and hypotheses.

The delta is used to adjust the this pointer. So we have to construct a case where:

After erasure, the getStringArr should return Object[], and it is able to cast to String[] without any problem.

Return type of the getStrArr, after type erasure, would be Object[] but, in your code, it is returning arr which is of type String[]. That is why there is not ClassCastException in your code.

Consider the following method (suppose generic arrays were allowed):
