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.

OperatorDescription
++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.

OperatorDescription
<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.

OperatorDescription
==Equality operator.
!=Inequality operator.

Assignment

Assigns a value to its left operand based on the value of its right operand.

OperatorDescription
=Assigns a value to a variable.

Binary Logical

Logical operators are typically used with Boolean (logical) values. Return a Boolean value.

OperatorDescription
&&Logical AND.
||Logical OR.

Arithmetic

Arithmetic operators take numeric values (either literals or variables) as their operands and return a single numerical value.

OperatorDescription
+Addition operator. Concatenates string types, adds integers, summarizes dates and time-related values.
-Subtraction operator.
*Multiplication operator.
/Division operator.
%Remainder operator.

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.

OperatorDescription
( )Overrides the normal operator precedence so that expressions with lower precedence can be evaluated before an expression with higher priority.
