mjsousa@945: *
mjsousa@945: *
mjsousa@945: * The Strict Datatype Model
mjsousa@945: * =========================
mjsousa@945: * The strict datatype model used by matiec considers any implicitly defined datatype
mjsousa@929: * (e.g. an array datatype defined in the variable declaration itself, instead of inside a TYPE ... END_TYPE
mjsousa@929: * construct) to be different (i.e. not the same datatype, and therefore not compatible) to any other
mjsousa@929: * datatype, including with datatypes declared identically to the implicit datatype.
mjsousa@929: * e.g.
mjsousa@929: * TYPE my_array_t: ARRAY [1..3] OF INT; END_TYPE;
mjsousa@929: * FUNCTION_BLOCK FOO
mjsousa@929: * VAR my_array: ARRAY [1..3] OF INT; END_VAR
mjsousa@929: * ...
mjsousa@929: * END_FUNCTION_BLOCK
mjsousa@929: *
mjsousa@929: * In the abive code, my_array is NOT considered to te compatible with my_Array_t !!!
mjsousa@929: *
mjsousa@929: * In essence, the currently supported datatype model considers all datatypes to be different to each other,
mjsousa@929: * even though the stored data is the same (Let us call this rule (0))!
mjsousa@929: * There are 2 exceptions to the above rule:
mjsousa@929: * (1) Datatypes that are directly derived from other datatypes.
mjsousa@929: * (this rule is specified in the standard, so we follow it!)
mjsousa@929: * (2) REF_TO datatypes that reference the same datatype
mjsousa@929: * (I dont think the standard says anything about this!)
mjsousa@945: * (This rule should actually be part of the relaxed datatype model, but for now we
mjsousa@945: * will leave it in the strict datatype model)
mjsousa@929: *
mjsousa@929: * TYPE
mjsousa@929: * my_array_1_t: ARRAY [1..3] OF INT;
mjsousa@929: * my_array_2_t: ARRAY [1..3] OF INT;
mjsousa@929: * my_array_3_t: my_array_1_t;
mjsousa@929: * A_ref_t: REF_TO my_array_1_t;
mjsousa@929: * B_ref_t: REF_TO my_array_1_t;
mjsousa@929: * C_ref_t: A_ref_t;
mjsousa@929: * END_TYPE;
mjsousa@929: *
mjsousa@929: * In the above code, my_array_1_t is a distinct datatype to my_array_2_t
mjsousa@929: * (this is different to C and C++, where they would be considered the same datatype!)
mjsousa@929: * (following rule (0))
mjsousa@929: * In the above code, my_array_3_t is the same datatype as my_array_1_t
mjsousa@929: * (following rule (1))
mjsousa@929: * In the above code, A_ref_t is the same datatype as B_ref_t
mjsousa@929: * (following rule (2))
mjsousa@929: * In the above code, A_ref_t is the same datatype as C_ref_t
mjsousa@929: * (following rule (1))
mjsousa@929: *
mjsousa@929: * Note that rule (0) means that a function/FB with a parameter whose datatype is implicitly defined
mjsousa@929: * can never be passed a value!
mjsousa@929: * FUNCTION_BLOCK FOO
mjsousa@929: * VAR_INPUT my_array: ARRAY [1..3] OF INT; END_VAR
mjsousa@929: * ...
mjsousa@929: * END_FUNCTION_BLOCK
mjsousa@929: *
mjsousa@929: * Any call to FB foo can never pass a value to parameter my_array, as its datatype is distinct
mjsousa@929: * to all other datatypes, and therefore passing any other variable to my_array will result in an
mjsousa@929: * 'incompatible datatypes' error!
mjsousa@929: * The above seems natural o me (Mario) in a programming language that is very strongly typed.
mjsousa@929: *
mjsousa@929: * However, if we did not have exception (2), the following would also be invalid:
mjsousa@929: * TYPE my_array_t: ARRAY [1..3] OF INT; END_TYPE;
mjsousa@929: * FUNCTION_BLOCK FOO_t
mjsousa@929: * VAR_INPUT my_array: REF_TO my_array_t; END_VAR
mjsousa@929: * ...
mjsousa@929: * END_FUNCTION_BLOCK
mjsousa@929: *
mjsousa@929: * FUNCTION_BLOCK BAR
mjsousa@929: * VAR
mjsousa@929: * my_array: my_array_t;
mjsousa@929: * foo: FOO_t;
mjsousa@929: * END_VAR
mjsousa@929: * foo(REF(my_array)); <----- invalid, without rule 2!!
mjsousa@929: * ...
mjsousa@929: * END_FUNCTION_BLOCK
mjsousa@929: *
mjsousa@929: * Rule/exception (2) goes against the datatype model used for all other datatypes.
mjsousa@929: * This rule was adopted as without it, the datatype of the value returned by the REF()
mjsousa@929: * operator would be considered distinct to all other datatypes, and therefore the
mjsousa@929: * REF() operator would be essentially useless.
mjsousa@945: *
mjsousa@945: *
mjsousa@945: * The Relaxed Datatype Model
mjsousa@945: * ==========================
mjsousa@945: * In the relaxed datatype model, the same rules as the strict datatype model are followed, with the
mjsousa@945: * exception of implicitly defined array datatypes, which are now considered equal if they define
mjsousa@945: * identical datatypes.
mjsousa@945: * This means that in the following example
mjsousa@945: * TYPE
mjsousa@945: * array_t: ARRAY [1..3] OF INT;
mjsousa@945: * END_TYPE;
mjsousa@945: * VAR
mjsousa@945: * array_var1: array_t;
mjsousa@945: * array_var2: ARRAY [1..3] OF INT;
mjsousa@945: * array_var3: ARRAY [1..3] OF INT;
mjsousa@945: * END_VAR
mjsousa@945: *
mjsousa@945: * all three variables (array_var1, array_var2, and array_var3) are considered as being of the
mjsousa@945: * same datatype.
mjsousa@945: *
mjsousa@945: * Note that the strict datatype model currently actually uses a relaxed datatype model for
mjsousa@945: * REF_TO datatypes, so in both the relaxed and strict datatype models matiec currently uses a
mjsousa@945: * relaxed datatype equivalince for REF_TO datatypes.
