Field Detail

pin

public final PinBase_FBcl pin

dataType

protected DataTypeRef_FBcl dataType

Reference to a dataType Reference. The references real dataType can be changed while code generation for more as one dedicated type and set return after generation.

steptime

public SteptimeRef_FBcl steptime

The steptime is only necessary if the module has no event connection. It is used to associate event cluster to FBlocks.

zVectorDim

public int zVectorDim

If not 0 then this port is a scalar port and the associated #fb can be used for a vector (sliced, for each) operation if the data type of connection is a vector.
That property of a Connection is defined with the kind of FBlock. Any simple block has this capability (num operation etc). A Callmodule_FBlock_JgenMdl-connection has this property >0 only if it is a for-each-subsystem and the port is a for-each-port.

Constructor Detail

PinDtype_FBcl

public PinDtype_FBcl(PinBase_FBcl pin)

Method Detail

setDataType

public void setDataType(DataTypeRef_FBcl src)

Sets the datatype form src. If this has a dataType its an error This will be registered on the src DataType

Parameters:

src - any given DataType.

dataType

public DataTypeRef_FBcl dataType()

gets the dataType.

adjustDataType

protected void adjustDataType(PinDtype_FBcl toDin)

Set the reference to the same instances of DataTypeRef_FBcl of both connection ends. One of twice existing instances is dissolved, all usages in other Connection ends are reassigned to the remaining only one. With that operation the number of different instances of DataTypeRef_FBcl are reduced to only one necessary.

Parameters:

toDin - the other end.

changeDataType

public void changeDataType(DataTypeRef_FBcl src)

This is the only one operation to set the type. It registers the connection on the src type calling DataTypeRef_FBcl#registerConnection(DInOut_FBcl). if a #dataType is stored already, this connection is deregistered there. Therewith clearing a type with src=null is admissible.

Parameters:

src - Any dataType, null is admissible.

changeDataTypeWithoutDeregister

public void changeDataTypeWithoutDeregister(DataTypeRef_FBcl src)

Change the data type, do not deregister the current one because prevent ConcurrentModificationException in the register list. This operation is only intent to call in DataTypeRef_FBcl.takeOverUsageFrom(DataTypeRef_FBcl) because all registered DataTypeRef_FBcl are replaced there.

Parameters:

src - type to use.

changeSteptime

public void changeSteptime(SteptimeRef_FBcl steptime)

Changes the steptime only for this connection. In conclusion the connections can have different steptimes though the steptimes should be the same due to the type fb. It is a special case for inf steptime.

Parameters:

steptime -

getSteptimeStr

public java.lang.String getSteptimeStr()

Returns the string representation of the Steptime.

Returns:

"?" if the steptime is not defined.

getSteptime

public SteptimeRef_FBcl getSteptime()

Returns the steptime reference to the instance.

setSteptimeToOtherCon

private void setSteptimeToOtherCon(Pin_FBcl[] thiscon,
                                   DinoutType_FBcl[] typecon,
                                   SteptimeRef_FBcl steptimeType)

propagateSteptime

public void propagateSteptime(SteptimeRef_FBcl steptime)
