Method Detail

buildExpressionFromDout

java.lang.String buildExpressionFromDout(java.lang.StringBuilder sExpr,
                                         Dout_FBcl doutSrc,
                                         Module_FBcl mdl,
                                         int recursion)

Builds the maybe complex combinatoric expression through all previous combinatoric FBlocks. It invokes genExprForDin(Din_FBcl, Module_FBcl) via genCodeAccess(StringBuilder, FBlock_FBcl, long, long, Module_FBcl, OutTextPreparer).

Parameters:

doutSrc -

mdl -

Returns:

genCodeAccess

boolean genCodeAccess(java.lang.StringBuilder dst,
                      FBlock_FBcl fb,
                      long mDin,
                      long mDout,
                      Module_FBcl mdl,
                      OutTextPreparer genCodeRule)

genExprForDin

private java.lang.String genExprForDin(Din_FBcl din,
                                       Module_FBcl mdl)
                                throws java.io.IOException

Returns the representing code snippet for the given input.

• If the input is unconnected, either a "0" or the value on the DinType_FBcl#getConstant() is written there. TODO maybe convert constants language-specific (suffix "l" for float values in C).
• If the Dout-src is a port-bin, its name is used. It is the a argument variable of the operation. That should be correct for any languages and conditions.
• If the Dout src comes from a FBlock_FBcl.dout either that contains a already calculated expression. That is in a event chain if the FBlock is processed before, especially in a expression wiring. Then this expression part is used as input value. It should be written in "(...)" already. With them expressions are built.
• It is possible that this expression contains an access to a instance variable, it is used if course. That is if the output is used more as one in the same or different expressions, elsewhere in the model.
• If the Dout src comes from a FBlock and it is not calculated yet, it comes from another expression part or , also possible, from a FBlock later in the event chain. In this case the appropriate instance variable is generated to this output and used. If the FBlock_FBcl.dout is processed later, this value is used. The decision that it is an instance variable access is regarded.

Parameters:

din -

mDinOfOperation - it is the mask for used din pins of this operation, found in the argument list.

Returns:

Throws:

java.io.IOException

addVariable

void addVariable(java.lang.String name,
                 Dout_FBcl dout)

genStatementsForLocalVars

java.lang.String genStatementsForLocalVars(Module_FBcl mdl)

Generates statement for local variables which are used in the expression before.

Parameters:

mdl -

Returns:
