Constant Field Values

dTypeKpin

protected DType_FBcl.DtIxmdl dTypeKpin

A possible specific data type for the pin. Usual the data types are stored in DinoutType_FBcl.dType as fix dtype in the pin type or in FBlock_FBcl.dTypes as type of maybe some more pins of this Pin_FBcl.fb adequate to the index given in DinoutType_FBcl#ixDtype. But for expressions it is possible that each input has a specific forward propagated data type which may be used for type casting in the generated code etc. If this type should be set then DinoutType_FBcl#ixDtype is marked with -2 instead -1 for a fix type.

xin

public final DinExpr_FBcl xin

The associated X input.

xrefname1

public transient java.lang.String xrefname1

Name of variables which are contained in the text of the X input but yet not referenced. They are searched and connected if the module is prepared.

xrefname2

public transient java.lang.String xrefname2

Name of variables which are contained in the text of the X input but yet not referenced. They are searched and connected if the module is prepared.

sOper

public java.lang.String sOper

An operator if given, first the binary operator with the input, following by the possible unary operator. it is stored originally (IEC61499) in the "expr" pin as Din_FBcl.sConstant as control String for the whole expression. See FBexpr_FBcl#setOperatorToPins(org.vishia.fbcl.readSource.Prj_FBCLrd) and FBexpr_FBcl.setExprPinFromPinsExprFn().

Constructor Detail

DinExprK_FBcl

public DinExprK_FBcl(DinExpr_FBcl xin,
                     DinType_FBcl pint,
                     java.lang.String name,
                     FBlock_FBcl fb)

Method Detail

getDTypeIxMdl

DType_FBcl.DtIxmdl getDTypeIxMdl()

Returns a String describing the DType situation. See Dinout_FBcl.dTypeCix(char[], int[]). If the internal dTypeKpin is set, then returns it and '!' for cDTBack, and the ixDTmdl from DType_FBcl.DtIxmdl.ixMdl(). If that is not set, it calls first Dinout_FBcl.dTypeCix(char[], int[]) which may return the set Din_FBcl.dTypeCastInp. If both are not set, the DType of the expression is returned.

Overrides:

getDTypeIxMdl in class Din_FBcl

Returns:

dTypePropgFwd

public DType_FBcl dTypePropgFwd()

Returns the particular DType dTypeKpin of this K pin. null if not set.

setDType

public java.lang.String setDType(DType_FBcl.DtIxmdl src,
                                 LogMessage log)

See Dinout_FBcl#setDType(DType_FBcl, DType_FBcl, org.vishia.msgDispatch.LogMessage)

Overrides:

setDType in class Din_FBcl

Parameters:

src -

Returns:

setDTypeExprK

public boolean setDTypeExprK(DType_FBcl.DtIxmdl dtix)

Sets initial the Dinout_FBcl.dType(). It it is set already, it is not changed. It means the first set DType wins. This is usual a declared DType of the pin, used for value casting in generated code.

Parameters:

dt -

Returns:

true if determined or equal, false if not set newly.
