ReadArray
File, Folder and Read functions ReadArray
- ReadArray(source, domainunit, valuetype, startposition, decimal-seperatorflag)
ReadArray(source, domainunit, valuetype, startposition, decimal-seperatorflag) results in an attribute, with row(s) of values, read from the source argument.
The second argument domainunit configures the domain unit of the resulting attribute
The third argument valuetype configures the value type of the resulting attribute
The fourth argument startposition configures the read position in the source. Spaces/tabs are used as delimiter.
The numbering of the positions is counted from left to right, meaning position two is the position of the second character in the first row.
The ReadArray function also generates a uint32 parameter subitem, called ReadPos. This parameter indicates the position of the next value after the value being read by the ReadArray function, see the example.
The ReadArray function is used to read a specific row from a text file, like an ini file.
Use the ReadValue function to read specific values from a text file.
- parameter source with string value type
- unit domainunit with value type from group CanBeDomainUnit
- valuetype can be any value type
- parameter startposition with uint32 value type
-
decimal-separator, an optional additional uint32
parameter or
literal
with two possible values:
- 0 (default value): indicates a point is interpreted as decimal seperator
- 1: indicates a comma is interpreted as decimal seperator.
