Examples with DynamicValueVectorExpression org.apache.hadoop.hive.ql.exec.vector.expressions.DynamicValueVectorExpression used on opensource projects

Example 1 with DynamicValueVectorExpression

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

the class VectorizationContext method getDynamicValueVectorExpression.

private VectorExpression getDynamicValueVectorExpression(ExprNodeDynamicValueDesc dynamicValueExpr, VectorExpressionDescriptor.Mode mode) throws HiveException {
    String typeName = dynamicValueExpr.getTypeInfo().getTypeName();
    VectorExpressionDescriptor.ArgumentType vectorArgType = VectorExpressionDescriptor.ArgumentType.fromHiveTypeName(typeName);
    if (vectorArgType == VectorExpressionDescriptor.ArgumentType.NONE) {
        throw new HiveException("No vector argument type for type name " + typeName);
    }
    int outCol = -1;
    if (mode == VectorExpressionDescriptor.Mode.PROJECTION) {
        outCol = ocm.allocateOutputColumn(dynamicValueExpr.getTypeInfo());
    }
    return new DynamicValueVectorExpression(outCol, dynamicValueExpr.getTypeInfo(), dynamicValueExpr.getDynamicValue());
}
