mongodb complex query on nested array

mongodb complex query on nested array

I have a single document in MongoDb whose structure is something like this
.. NESTED ARRAY. I want to $addToSet into d:["x","y"] to make it
d:["x","y","z"].
I have tried out $elemMatch and $. But they only work at a SINGLE LEVEL of
array.
{
id:1,
a:[
{
id:2,
b:[
{
id:3,
c:[
{
id:4,
d:["x","y"]
},
{
id:5,
d:["p","q"]
}
]
},
{
id:13,
c:[
{
id:14,
d:["w","q"]
},
{
id:15,
d:["i","j"]
}
]
}
]
}
]
}
What will be the query to get d:["x","y","z"] where query part could be ..
{id:1, "a.id":2, "a.b.id":3, "a.b.c.id":4 } or may be using $elemMatch ?

Wait for Android animation to finish

Wait for Android animation to finish

I was wondering if anyone could help me out, I've been looking everywhere
for usefull help, but found nothing. I have four View elements (Buttons),
and I need to animate them, in random order, one after the other. I've
tried waiting for Animation.hasEnded(), that just freezes the entire app.
Also I tried waiting for an AnimationListener to change a boolean from
onAnimationEnd(), but that also froze the app. Both Thread.sleep() and
SystemClock.sleep() for waiting gave the same result. Please, can someone
help me?

I want make a 4*P matrix from P numbers
P=p1+p2+p3+p4
X=[x11 ... x1p1 0...0 0...0 0...0 ; 0...0 x2p1+1 ... x2p2 0...0 0...0 ;

How to read a txt file line by line in R/RstudioH

How to read a txt file line by line in R/RstudioH

Suppose I have a messy text file like the following for example
Today is a good
day, but I feel very tired. It seems like it is
going to rain pretty soon.
I want to read the txt file into R as a character vector exactly the way
it appears as in the original text file. In other words, I want to have
the first element of the character vector being the first line, second
element of the character vector being the second line, etc, as below
char_vector[1] = "Today is a good"
char_vector[2] = "day, but I feel very tired. It seems like it is"
char_vector[3] = "going to rain pretty soon."
I have tried read.table and read.csv, but it's always the case that some
lines join together as one line. Is there a way to fix this?

rs.ListChildren.
Any Ideas?
