Example 1 with DoubleColUnaryMinus

use of org.apache.hadoop.hive.ql.exec.vector.expressions.gen.DoubleColUnaryMinus in project hive by apache.

the class TestVectorizationContext method testUnaryMinusColumnDouble.

@Test

    children.add(col1Expr);
    ExprNodeGenericFuncDesc negExprDesc = new ExprNodeGenericFuncDesc(TypeInfoFactory.doubleTypeInfo, gudf, children);
    List<String> columns = new ArrayList<String>();
    columns.add("col0");
    columns.add("col1");
    VectorizationContext vc = new VectorizationContext("name", columns);
    VectorExpression ve = vc.getVectorExpression(negExprDesc, VectorExpressionDescriptor.Mode.PROJECTION);
    assertTrue(ve instanceof DoubleColUnaryMinus);
