parse[int|real|string]array

Prototype: parseintarray(array, input, comment, split, maxentries, maxbytes)
Prototype: parserealarray(array, input, comment, split, maxentries, maxbytes)
Prototype: parsestringarray(array, input, comment, split, maxentries, maxbytes)

Return type: int

Description: Parses up to maxentries values from the first maxbytes bytes in string input and populates array. Returns the dimension.

These functions mirror the exact behavior of their read[int|real|string]array() counterparts, but read data from a variable instead of a file. By making data readable from a variable, data driven policies can be kept inline.

Arguments:

• array : Array identifier to populate, in the range [a-zA-Z0-9_$(){}\[\].:]+
• input : A string to parse for input data, in the range "?(/.*)
• comment : Unanchored regex matching comments, in the range .*
• split : Unanchored regex to split data, in the range .*
• maxentries : Maximum number of entries to read, in the range 0,99999999999
• maxbytes : Maximum bytes to read, in the range 0,99999999999

Example:

body common control
{
      bundlesequence => { "test" };
}

bundle agent test(f)
{
  vars:
      # Define data inline for convenience
      "table"   string =>
      "1:2
          3:4
          5:6";

      "dim" int => parseintarray(
                                  "items",
                  "$(table)",
                  "\s*#[^\n]*",
                  ":",
                  "1000",
                  "200000"
      );

      "keys" slist => getindices("items");
      "sorted_keys" slist => sort(keys, "int");

  reports:
      "$(sorted_keys)";
}

Output:

R: 1
R: 3
R: 5
