Given the path string, if the variable is present, and is a scalar, then update its value. If it is not present, then create it and set its value.
| Type | Intent | Optional | Attributes | Name | ||
|---|---|---|---|---|---|---|
| class(json_core), | intent(inout) | :: | json | |||
| type(json_value), | pointer | :: | p | |||
| character(kind=CK,len=*), | intent(in) | :: | name | |||
| integer(kind=IK), | intent(in) | :: | val | |||
| logical(kind=LK), | intent(out) | :: | found |
Nodes of different colours represent the following:
Solid arrows point from a procedure to one which it calls. Dashed arrows point from an interface to procedures which implement that interface. This could include the module procedures in a generic interface or the implementation in a submodule of an interface in a parent module. Where possible, edges connecting nodes are given different colours to make them easier to distinguish in large graphs.
