Operators
The workflow programming language supports several standard Java operations. These operations are special symbols that performing specific operations on one or more operands and return a result.
| Operators by Type | |||
|---|---|---|---|
Unary
A unary operation is an operation with only one operand.
| Operator | Description |
|---|---|
++ | Increases the value of an operand by 1. |
-- | Decreases the value of an operand by 1. |
! | Logical NOT. |
Relational
A relational operator compares the relationship between two entities.
Returns a Boolean value that states whether the comparison is true or false.
| Operator | Description |
|---|---|
< | Less than operator. |
> | Greater than operator. |
<= | Less than or equal operator. |
=> | Greater than or equal operator. |
Equality
Evaluates the equivalence of two operators.
Returns a Boolean value that states whether the equivalence is true or false.
| Operator | Description |
|---|---|
== | Equality operator. |
!= | Inequality operator. |
Assignment
Assigns a value to its left operand based on the value of its right operand.
| Operator | Description |
|---|---|
= | Assigns a value to a variable. |
Binary Logical
Logical operators are typically used with Boolean (logical) values. Return a Boolean value.
| Operator | Description |
|---|---|
&& | Logical AND. |
|| | Logical OR. |
Arithmetic
Arithmetic operators take numeric values (either literals or variables) as their operands and return a single numerical value.
The + and - operators can also be used with dates, periods, and durations.
For more information, see Working with Dates and Times.
Grouping
The grouping operator consists of a pair of parentheses around an expression or sub-expression.
| Operator | Description |
|---|---|
( ) | Overrides the normal operator precedence so that expressions with lower precedence can be evaluated before an expression with higher priority. |
