Aimsun Next API Scenario Management

Get ANG Replication Identifier

In C++ and Python

Explanation

Get the replication Identifier.

Format
unsigned int ANGConnGetReplicationId ();
Parameters

None.

Output
  • > 0: Replication Identifier.
  • = 0: Error.

Get ANG Experiment Identifier

In C++ and Python

Explanation

Get the experiment Identifier.

Format
unsigned int ANGConnGetExperimentId ();
Parameters

None.

Output
  • > 0: Experiment Identifier.
  • = 0: Error.

Get ANG Scenario Identifier

In C++ and Python

Explanation

Get the scenario identifier.

Format
unsigned int ANGConnGetScenarioId ();
Parameters: None.
Output
  • > 0: Scenario identifier.
  • = 0: Error.

Get ANG Scenario Simulated Date and Initial Time

In C++ and Python

Explanation

Get the scenario Simulated Date and Initial Time.

Format
const char * ANGConnGetScenarioTime();
Parameters

None.

Output
  • ≠ NULL: Returns a string with the scenario date and time using ISO 8601 extended format (YYYY-MM-DDTHH:MM:SS),or an empty string if no information is available. Do not delete this string.
  • = NULL: Error.

Get ANG Object ID

In C++ and Python

Explanation

Get the Object ID of any object by name.

Format
int ANGConnGetObjectId( const unsigned short * name, bool deleteUShortName  ); // Deprecated
int ANGConnGetObjectIdByType( const unsigned short * name, const unsigned short * typeName, bool deleteUShortName  );
Parameters
  • name: The name of the object.
  • typeName: Filters the search by the object type name. When NULL, it returns the first object that matches the name.
  • deleteUShortName: true if the name is to be deleted automatically.
Output
  • > 0: object id.
  • < 0: the object doesn’t exist.

Get ANG Object Attribute

In C++ and Python

Explanation

Get a pointer to an attribute of an ANG object. This pointer can be used to modify or read the value of the attribute of different objects, using functions ANGConnSetAttributeValue or ANGConnGetAttributeValue. In Aimsun Next, the internal attribute names of each object type can be displayed by selecting Window / Type from the main menu.

Format
void * ANGConnGetAttribute(const unsigned short * internalAttrName );
Parameters
  • internalAttrName: The internal name of the attribute.
Output
  • ≠ NULL: pointer to attribute.
  • = NULL: Error.

Create ANG Object Attribute

In C++ and Python

Explanation

Create an attribute of one ANG object. This pointer can be used to modify or read the value of the attribute of different objects, using functions ANGConnSetAttributeValue or ANGConnGetAttributeValue. The internal attribute names of each object type can be displayed by selecting Window / Type from the main menu.

Format
void * ANGConnCreateAttribute(const unsigned short * typeName, const unsigned short * internalAttrName, const unsigned short * externalAttrName, int attrType, int columnType);
Parameters
  • typeName: Name of the ANG object.
  • internalAttrName: Internal name of the attribute.
  • externalAttrName: External name of the attribute (as displayed in the editors of the object).
  • attrType: INTEGER_TYPE as integer, DOUBLE_TYPE as double or STRING_TYPE as a string.
  • columnType: Defines the way to store the column as EXTERNAL_TEMPORAL, INTERNAL or EXTERNAL.
Output
  • ≠ NULL: pointer to attribute.
  • = NULL: Error.

Set value to ANG Object Attribute

In C++ and Python

Explanation

Set the value to an attribute of an ANG object. UNICODE version.

Format
void ANGConnSetAttributeValueString( void * attr, unsigned int objectId, const unsigned short * value ); // Unicode version. Not available in Python.
void ANGConnSetAttributeValueStringA( void * attr, unsigned int objectId, const char * value );  // Ascii version.
void ANGConnSetAttributeValueInt ( void * attr, unsigned int objectId, int value );
void ANGConnSetAttributeValueDouble ( void * attr, unsigned int objectId, double value );
Parameters
Output

None.

Get value from ANG Object Attribute

In C++ and Python

Explanation

Get the value of an attribute of an ANG object.

Format
const unsigned short * ANGConnGetAttributeValueString(void * attr, unsigned int objectId); // Unicode version. Not available in Python.
const char * ANGConnGetAttributeValueStringA(void * attr, unsigned int objectId); // Ascii version.
int ANGConnGetAttributeValueInt( void * attr, unsigned int objectId );
double ANGConnGetAttributeValueDouble( void * attr, unsigned int objectId );
Parameters
Output

Returns the value, according to the attribute type (integer, double or string).

Get number of values in a Time Series ANG Object Attribute

In C++ and Python

Explanation

Get number of values of a time series attribute of an ANG object.

Format
int ANGConnGetTimeSeriesSize( void * attr, unsigned int objectId );
Parameters
Output

Returns the number of values.

Get value in a Time Series ANG Object Attribute

In C++ and Python

Explanation

Get a value of a time series attribute of an ANG object.

Format
double ANGConnGetTimeSeriesValue( void * attr, unsigned int objectId, unsigned int pos );
Parameters
  • attr: Pointer of the attribute, obtained calling either ANGConnGetAttribute or ANGConnCreateAttribute.
  • objectId: Object identifier.
  • pos: Position of the value in the Time Series attribute (from 0 to (ANGConnGetTimeSeriesSize(attr, objectId )-1).
Output

Returns the value.
