Field Detail

sOperator

public java.lang.String sOperator

The operator for the pin, consisting of till three parts.

• If starts with "C" it is a value cast from the input to the DType of the pin.
• Following by the operator itself: , means "+" "-" or also ">=" etc. The binary operator of the X1 is remove if it is adequate the expression kind, or it is replaced here by "1.0 /" if the first pin divides. Note: Division can be seen also as unary operator: Build the reciprocal. Adequate that is done by the "-" unary for ADD operations.
• Following by a possible unary operator.

Generally in an expression the operators are contained in the first pin named "expr" as String. But in the working data it is stored here. See FBexpr_FBcl.setOperatorToPins(org.vishia.fbcl.readSource.Prj_FBCLrd) and FBexpr_FBcl.setExprPinFromPinsExprFn().

sElemSrc

protected java.lang.String sElemSrc

If not null or "", then it describes the access to an element in the connected doutSrc struct as textual information written in an din. An element access is such as ".re" or ".im" for complex values or also ".element" for a struct access. It should not be confused with the ".re" designation for element assign to the output variable of an expression. This is a really textual access description possibility.

sElemDst

protected java.lang.String sElemDst

This is either used for setElement expression (to set an array element or a struct element in the correspond variable after expression) or also to store a given component name for sliced accesses.

pinK

private DinExprK_FBcl pinK

The associated K pin for a second input of a constant to operate. null if a K pin is not designated.
