Configuration Scripts

enaio® appconnector • 11.10 »

To guarantee processing in the script environment the internal names of the enaio® object types have to be structured as follows: names start with letters from a to z or from A to Z or with the characters _ or &. After this, the characters 0 to 9, a to z, A to Z, _ or $ can be used. The names of variables are case-sensitive.

The following names are reserved and cannot be used as variable names: or, and, eq, ne, lt, gt, le, ge, div, mod, not, null, true, false, and new.

You can use the scripting language described below to assign the index data fields in the OSMetadata.xml configuration file from enaio® to the enaio® apps fields.

Statements Use a semicolon to terminate statements.
Blocks Blocks are different statements enclosed by braces.
Assignments Values can be assigned to variables using the equals sign: var='Value'.

Integer One or more digits from 0 to 9.
Floating Point One or more digits from 0 to 9 followed by a decimal point and further digits from 0 to 9.
Boolean true or false
String Strings enclosed by single quotation marks: 'Hello world.'

empty Returns true if the following expression is null. An empty string, for example, empty(var1).
size Returns the length of a string, for example size('Hello').

Logical operators

AND:

cond1 and cond2

cond1 && cond2

OR:

cond1 or cond2

cond1 || cond2

NOT:

!cond1

not cond1

Conditional operators

The common operator "condition ? if_true : if_false" as well as the short form

"value ?: if_false" can be used. For example,

val1 ? val1 : val2

val1 ?: val2

Relational operators

val1 == val2

val1 eq val2

val1 != val2

val1 ne val2

val1 < val2

val1 lt val2

val1 <= val2

val1 le val2

val1 >= val2

val1 ge val2

Regular expressions

var1 =~ 'abc.*'

var1 !~ 'abc.*'

Calculations

The operations of addition, subtraction, multiplication, and division can be carried out:

val1 + val2

val1 - val2

val1 * val2

val1 / val2

val1 div val2

if

if ((x * 2) == 5) {

y = 1;

}

else {

y = 2;

}
