Fields

Name of the program item. It can contain spaces.

prsTProgType Type

Type of the program item.

int iID

Identification number of the program item. It must be unique within process.

prsTProgType Pair

Type of pair of this program item. This information is used by code generator.

PprsSource Sources

Source codes (one or two) of the program item, or NULL if there is no C-source code attached into this program item.

PCollection Connections

List of connections to other items.

PCollection Ports

List of references to port objects if this item is a communacator.

PprsItemColl NestedItems

struct
{
iopValue Blocking;
} Options

This structure holds options associated with the program item. Options are:

iopValue Blocking

This options specifies, if the sending operation is blocked or not. It is used in CAO item only.

Methods

Constructor of the program item class.

virtual ~TprsItem(void)

Destructor of the program item class.

virtual int Init(void)

Initialization of the object. This method must be called after constructor immediately when a new program item object is instantiated.

virtual void SetOption(iopType what, iopValue val, void *inf)

This function is used to set up a field in the Options structure.

virtual void ShowData(FILE *To, char *Pre)

Printing out values of data of the object in file To. It writes out Pre string at beginning of every generated lines.

virtual void WriteGRP(FILE *To, int Ind)

This object generates GRP code of the program item in file To. It indents lines by Ind characters.

Method index of TprsItemColl

Methods

Constructor of program item collection class.

virtual ~TprsItemColl(void)

Destructor of the program item collection class.

virtual int Compare(void *Key1, void *Key2)

This function overrides inherited Compare method and implements special comparition to order program items by their identification number.

void InsertItem(PprsItem Item)

This method checks if Item program item is on the collection and if it is not then inserts it to the collection.

virtual void *KeyOf(void *Item)

This method is used for get address of key field of the items of the collection. It returns address of iID field if Item (it assumes that Item is a program item object.

virtual void ShowData(FILE *To, char *Pre)

This method prints out values of data fileds of the object to To file and prints Pre string at beginning of every produced lines.

virtual void WriteGRP(FILE *To, int Ind)

This method generates GRP code of the object in To file and indents lines by Ind characters.
