A guide to all the available operator transformations on Alumio
Addition
As the name indicates the transformer performs addition operations on two fields (can also be with itself), and the result is dumped into the destination path of your choice.
An example implementation of this transformation is as shown below.
Subtraction
As the name indicates the transformer performs subtraction operations on two fields (can also be with itself), and the result is dumped into the destination path of your choice.
An example implementation of this transformation is as shown below.
Multiplication
Arithmetic operator to perform multiplications using 2 fields (self-reference allowed). The result will be stored in the destination path specified.
=
Division
Arithmetic operator to perform division using 2 fields (self-reference allowed). The result will be stored in the destination path specified.
Array difference [Set operation A-B]
Set operation A minus B, which is to retain the elements of Set A that is not present in B.
Example: A = {1, 2, 3} and B = {2, 4} then A-B = {1,3}, the element {4} is discarded as it not an element of Set A.
Array Key Diff
Unlike the array difference where values are matched, here the difference between index positions is determined.
Example: If A = {1, 2, 3} and B = {2, 3}; then their indexes would be
Aindex = {1, 2, 3} and Bindex ={1, 2}; Aindex - Bindex = {3}.
Array Intersect
Set operation A ∩ B, where the common elements between A and B are retained.
Array Intersect keys
Similar to array intersect operation, but here the indexes are returned.
TODO: Improve explaination
Array Merge or Union
Set operation A ∪ B, the resulting set will contain all the elements contained within A and B.
Bitwise AND
Bitwise AND operation that retains bits that are common in the Left and Right numbers.
Example:
0101 (decimal 5)
AND 0011 (decimal 3)
= 0001 (decimal 1)
Bitwise OR
Bitwise OR operation that retains the bits if either one of the Left and Right numbers displays a high(1).
Example:
0101 (decimal 5)
OR 0011 (decimal 3)
= 0111 (decimal 7)
Bitwise Shift left
Shifts the "Data container left path" bits left to the count mentioned in the "Data container right path".
Bitwise shift right
Shifts the "Data container left path" bits right to the count mentioned in the "Data container right path".
Bitwise XOR
BitwiseXOR operation that retains the bits if 1-0 and 0-1 patterns are observed between the two numbers.
Example:
0101 (decimal 5)
XOR 0011 (decimal 3)
= 0110 (decimal 6)
Concatenation
Concatenates the Left and Right Data containers by implicitly converting them to string type.
Logical AND
Logical AND operator
| A | B | A ^ B |
| T | T | T |
| T | F | F |
| F | T | F |
| F | F | F |
Logical OR
Logical OR operator
| A | B | A v B |
| T | T | T |
| T | F | T |
| F | T | T |
| F | F | F |
Logical XOR
Logical XOR operator
| A | B | A xor B |
| T | T | F |
| T | F | T |
| F | T | T |
| F | F | F |
Max
Determine the max value between the Left and Right coefficient. If Left and Right are array type, then the array with the max element will be returned.
Min
Determine the min value between the Left and Right coefficient. If Left and Right are array type, then the array with the min element will be returned.
Mod
Modulous operator, the Left mod Right operation is performed and the resulting remainder is returned.
Pow
The exponential power of the Left to the power Right (Left^Right) is performed.
String: Replace
Replaces the Substring or String of the Left string with empty if there is an exact match with the Right string.
