ValueCount include both null and not null values. Perhaps a better name
for the method would have been setSize or setLength.

Thanks for your answer. I have one more question. In this test function for
example (

there is a for loop which tries to fill in some values but not all values.

Hi Azim,
According to the current API, after filling in some values, you have to set
the value count manually (through the setValueCount method).
Otherwise, the value count remains 0.
Best,

Thanks for your answer. So the valueCount shows the number of data filled
in the vector.
Then I would like to ask you why the valueCount after setting some values
is 0? for example: (

Hi Azim,
I think we should be aware of two distinct concepts:
1. vector capacity: the max number of values that can be stored in the
vector, without reallocation
2. vector length: the number of values actually filled in the vector
For any valid vector, we always have vector length <= vector capa
Hi everyone,
I have a question about the Java implementation of Apache Arrow. Should we
always call setValueCount after creating a vector with allocateNew()?
I can see that in some tests where setValueCount is called immediately
after allocateNew. For example here:
