Miro-Andrin opened a new issue, #383:
URL: https://github.com/apache/arrow-cookbook/issues/383
```java
import org.apache.arrow.memory.BufferAllocator;
import org.apache.arrow.memory.RootAllocator;
import org.apache.arrow.vector.VarCharVector;
try(
BufferAllocator allocator = new RootAllocator();
VarCharVector varCharVector = new VarCharVector("varCharVector",
allocator);
) {
varCharVector.allocateNew(3);
varCharVector.set(0, "one".getBytes());
varCharVector.set(1, "two".getBytes());
varCharVector.set(2, "three".getBytes());
varCharVector.setValueCount(3);
System.out.print(varCharVector);
}
```
This snippet only works because few short strings are written. allocateNew
does not grow the data buffer depending on the size of n (3 in this case). The
example should either call the allocateNew method variant that specifies the
byte count, use setSafe, or have a comment about this.
