ARROW-1237: [JAVA] expose the ability to set lastSet #868
Conversation

Is it possible to add a unit test for this? Can you also indicate in the PR title that this is a Java patch, e.g. |

Let's add some unit tests for each version that has last set. Basically, set some data via memory access then update last set, then confirm a correct vector output.

Is there a lastset for the list vector as well?

Writing the unit tests.
Yes, the ListVector also has lastSet. Will add the API for ListVector as well and unit tests for each vector type; NullableVarCharVector, NullableVarBinaryVector, ListVector.

@jacques-n There is a slightly orthogonal test case test based on VectorLoader and VectorUnloader. |
| final NullableVarCharVector.Accessor accessor1 = vector1.getAccessor(); | ||
| assertArrayEquals(STR1, accessor1.get(0)); | ||
| assertArrayEquals(STR2, accessor1.get(1)); | ||
| assertArrayEquals(STR3, accessor1.get(2)); |

Given the main issue of holes/blanks in the items set, I suggest you modify these tests to set the valuecount to something higher (e.g. 15). Then verify that everything looks good.

Added additional test and slightly modified existing ones.
The changes here expose the ability to set "lastSet" on Nullable<var length>Vector. I believe this is needed only for NullableVarCharVector and NullableVarBinaryVector. Hence the API is exposed through NullableValueVectors.java Author: siddharth <[email protected]> Closes apache#868 from siddharthteotia/ARROW-1237 and squashes the following commits: 786dfea [siddharth] ARROW-1237: addressed review comments and added more tests 73b2fc5 [siddharth] ARROW-1237: added some unit tests f8c7277 [siddharth] ARROW-1237: expose the ability to set lastSet
