17 | class IntParam from IFSelect inherits TShared |
18 | |
19 | ---Purpose : This class simply allows to access an Integer value through a |
20 | -- Handle, as a String can be (by using HString). |
21 | -- Hence, this value can be accessed : read and modified, without |
22 | -- passing through the specific object which detains it. Thus, |
23 | -- parameters of a Selection or a Dispatch (according its type) |
24 | -- can be controlled directly from the ShareOut which contains them |
25 | -- |
26 | -- Additionnaly, an IntParam can be bound to a Static. |
27 | -- Remember that for a String, binding is immediate, because the |
28 | -- string value of a Static is a HAsciiString, it then suffices |
29 | -- to get its Handle. |
30 | -- For an Integer, an IntParam can designate (by its name) a |
31 | -- Static : each time its value is required or set, the Static |
32 | -- is aknowledged |
33 | |

39 | ---Purpose : Creates an IntParam. Initial value is set to zer |
40 | |
41 | SetStaticName (me : mutable; statname : CString); |
42 | ---Purpose : Commands this IntParam to be bound to a Static |
43 | -- Hence, Value will return the value if this Static if it is set |
44 | -- Else, Value works on the locally stored value |
45 | -- SetValue also will set the value of the Static |
46 | -- This works only for a present static of type integer or enum |
47 | -- Else, it is ignored |
48 | -- |
49 | -- If <statname> is empty, disconnects the IntParam from Static |
50 | |
51 | StaticName (me) returns CString; |
52 | ---Purpose : Returns the name of static parameter to which this IntParam |
53 | -- is bound, empty if none |
54 | |
55 | Value (me) returns Integer is static; |
56 | ---Purpose : Reads Integer Value of the IntParam. If a StaticName is |
57 | -- defined and the Static is set, looks in priority the value |
58 | -- of the static |
59 | |
60 | SetValue (me : mutable; val : Integer) is static; |
61 | ---Purpose : Sets a new Integer Value for the IntParam. If a StaticName is |
62 | -- defined and the Static is set, also sets the value of the static |
