ObsFunctionStringManipulation

This obsFunction is designed to provide a means for manipulating strings. The current available string manipulations are:

• string cut

Required input parameters:

variable

An array of the variable for string manipulation supplied as a vector of strings.

string operation

A key word which will set what type of string manipulation is to be carried out.

• stringcut

  String cut will slice an input string from a given starting index for a set length.

  Required stringcut parameters:

  For the stringcut option the following inputs are required

  startIndex

  An integer that will set what index to start the cut from (0 being far left)

  cutLength

  An integer that will set the length of the string to cut from the startIndex.

Example configuration:

Here is an example for creating a new station_name variable from a ground based gnss station name processing name combination. In this example the full_site_name@MetaData might look like AAAA-BBBB.

- filter: Variable Assignment
  assignments:
  - name: station_name@MetaData
    type: string
    function:
      name: StringManipulation@StringObsFunction
      options:
        string operation: stringcut
        variable: [full_site_name@MetaData]
        startIndex: 0
        cutLength: 4

The output station_name@MetaData would then look like AAAA.
