aot_path_addNode Subroutine

public subroutine aot_path_addNode(me, NodeType, pos, key)

With this subroutine a node is appended to the end of the list of nodes of the given path.

You need to provide a NodeType (table or function), and either its position or key to identify it in the parent object.

Arguments

Type IntentOptional Attributes Name
type(aot_path_type), intent(inout) :: me

Path to append the node to
character(len=*), intent(in) :: NodeType

Type of the node (table of function)
integer, intent(in), optional :: pos

Position in the parenting table
character(len=*), intent(in), optional :: key

Key within the parenting table
