java - How to make a modulo function in Apache Arrow?

Question

//**  x%2==0 <-- This is the condition which I want to evaluate **//

Code using Apache Arrow looks like:

Field a = Field.nullable("a",int64);
TreeNode b = TreeBuilder.makeLiteral(2);
TreeNode zero =TreeBuilder.makeLiteral(0);

Now I want to make a modulo function to filter on condition whether entry in field a is even or not and then I want to segregate them. What are the next steps which I should add to this code? For ex: when I try :

TreeNodemodulo=TreeBuilder.makeFunction( "modulo",Lists.newArrayList(TreeBuilder.makeField(a),b),int32); it says that there is no such modulo function.
