Logic Funtions

Equals

Evaluates if arg1 is equal to arg2

arg1 = arg2
equals(arg1, arg2)

Examples

'foo' = 'bar'
> false
'foo' = 'foo'
> true
51 = 50
> false
50 = 50
> true

equals('foo', 'bar')
> false
equals('foo', 'foo')
> true
equals(51, 50)
> false
equals(50, 50)
> true

Note that equals cannot be applied to null and error values, e.g. x=null() or x=err(). The isNull() and isError() functions must be used instead.

Greater Than

Evaluates if arg1 is greater than to arg2

arg1 > arg2
greaterThan(arg1, arg2)

Examples

51 > 50
> true
50 > 50
> false
49 > 50
> false

greaterThan(51, 50)
> true
greaterThan(50, 50)
> false
greaterThan(49, 50)
> false

Greater Than or Equal To

Evaluates if arg1 is greater than or equal to arg2

arg1 >= arg2
greaterThanOrEqualTo(arg1, arg2)

Examples

51 >= 50
> true
50 >= 50
> true
49 >= 50
> false

greaterThanOrEqualTo(51, 50)
> true
greaterThanOrEqualTo(50, 50)
> true
greaterThanOrEqualTo(49, 50)
> false

If

Evaluates the supplied boolean condition and returns one value if true or another if false

if(expression, trueReturnValue, falseReturnValue)

Examples

if(5 < 10, 'foo', 'bar')
> 'foo'
if(5 > 10, 'foo', 'bar')
> 'bar'
if(isNull(null()), 'foo', 'bar')
> 'foo'

Less Than

Evaluates if arg1 is less than to arg2

arg1 < arg2
lessThan(arg1, arg2)

Examples

51 < 50
> false
50 < 50
> false
49 < 50
> true

lessThan(51, 50)
> false
lessThan(50, 50)
> false
lessThan(49, 50)
> true

Less Than or Equal To

Evaluates if arg1 is less than or equal to arg2

arg1 <= arg2
lessThanOrEqualTo(arg1, arg2)

Examples

51 <= 50
> false
50 <= 50
> true
49 <= 50
> true

lessThanOrEqualTo(51, 50)
> false
lessThanOrEqualTo(50, 50)
> true
lessThanOrEqualTo(49, 50)
> true

And

If all supplied arguments evaluate to true then return true, else false.

and(booleanValue, booleanValue)

Or

If one or more of the supplied arguments evaluate to true then return true, else false.

or(booleanValue, booleanValue)

Not

Inverts boolean values making true, false etc.

not(booleanValue)

Examples

not(5 > 10)
> true
not(5 = 5)
> false
not(false())
> true

Case

Works much like a Java Switch/Case statement. The arguments are split into 3 parts

1. The input value to test
2. Pairs of test values with their respective output value
3. A default result, if the input doesn’t match any of the test values

case(input, test1, result1, test2, result2, ... testN, resultN, otherwise)

Example

case(${val}, 1, 'one', 2, 'two', 3, 'three', 'unknown')
${val}=1
> one
${val}=2
> two
${val}=4
> unknown // falls back to the 'otherwise' value
