DMN13 — Built-in functions only described in chapter " Context", and not described in the "10.3.4 Built-in functions"

  • Key: DMN13-126
  • Status: closed  
  • Source: Red Hat ( Matteo Mortari)
  • Summary:

    In section " Context" two built-in functions are described: get value(), get entries().
    However these functions are not summarized later in section "10.3.4 Built-in functions"

    Describing all built-in functions in latter section "10.3.4 Built-in functions" is important to agree on the function parameters name.

    Agree on the function parameters name is important for invoking function and binding parameters by name, rather than positional.

    I propose to add a new section inside "10.3.4 Built-in functions", with the following:

    10.3.4.x Context function

    Table xx defines Context functions.

    Table xx: Semantics of Context functions

    Name(parameters) Parameter Domain Description Example
    get value(m, key) context, string select the value of the entry named key from context m
    get value({key1 : "value1"}, "key1") = "value1"
    get value({key1 : "value1"}, "unexistent-key") = null
    get entries(m) context produces a list of key,value pairs from a context m
    get entries({key1 : "value1"}) = [ { key : "key1", value : "value1" } ]
    get entries({key1 : "value1"})[key="key1"].value = "value1"
