Ji Liu created ARROW-6200:
-----------------------------
Summary: [Java] Method getBufferSizeFor in
BaseRepeatedValueVector/ListVector not correct
Key: ARROW-6200
URL: https://issues.apache.org/jira/browse/ARROW-6200
Project: Apache Arrow
Issue Type: Bug
Components: Java
Reporter: Ji Liu
Assignee: Ji Liu
Currently, {{getBufferSizeFor}} in {{BaseRepeatedValueVector}} implemented as
below:
{code:java}
if (valueCount == 0) {
return 0;
}
return ((valueCount + 1) * OFFSET_WIDTH) + vector.getBufferSizeFor(valueCount);
{code}
Here vector.getBufferSizeFor(valueCount) seems not right which should be
{code:java}
int innerVectorValueCount = offsetBuffer.getInt(valueCount * OFFSET_WIDTH);
vector.getBufferSizeFor(innerVectorValueCount)
{code}
ListVector has the same problem.
