Class GenJava_Operation_JgenMdl

java.lang.Object

org.vishia.fbcl.genMdl.GenJava_Operation_JgenMdl

public class GenJava_Operation_JgenMdl
extends java.lang.Object

Contains data for one operation in Java for one Module. The Java class contains only one operation, because it is the class for the module with the internal UnitDelay variable. TODO maybe nested blocks may build a second Java operation. It is TODO yet.

Field Detail

nameOperation

java.lang.String nameOperation

inports

java.util.Map<java.lang.Integer,FBlock_Port_JgenMdl> inports

Inports for this operation. The Integer is the port number in the module. It is used as key to prevent multiple adding an Inport if the signal is used more as one.

outports

java.util.Map<java.lang.Integer,FBlock_Port_JgenMdl> outports

Outports for this operation. They are sorted to the FBlock_Port_JgenMdl.ixPortInModuleBlock but the operation do not use all ports.

outportRet

FBlock_Port_JgenMdl outportRet

outport which is used as return on generating the operation. It is the last statement.
Note: On DataType_FBcl.sizeArray ==0 (scalar) it produces a return statement. On vector it produces a vector element assignment.

ixOutRet

int ixOutRet

Index of the return Output port in the Module_FBlock_JgenMdl#conout.

outconRet

ConnOut_FBcl outconRet

The OutConnection of the last block to an FBlock_Port_JgenMdl is the return value of this operation, set in #genJava_Operation(Appendable). It is used in genJava_CallOperationForAtomicStepOperation(Appendable).

blocks

java.util.List<FBlock_JgenMdl> blocks

Sorted blocks in order of calculation, created in #.

steptime

public int steptime

The step time of the operation, same as the ports. It is a number which determines the time slice. It may be the microseconds time, or any other characteristic number.

operationBlock

final Operation_FBlock_JgenMdl operationBlock

The block which presents the operation in a block model. Either the Module (builds clazz is a library module, then this block will be copied to the instance block. Or the Module is immediately, then this blocks are used instead the module block.

clazz

GenJava_Class_JgenMdl clazz

Constructor Detail

GenJava_Operation_JgenMdl

GenJava_Operation_JgenMdl(GenJava_Class_JgenMdl clazz,
                          int steptime,
                          boolean bUpdate)

Method Detail

completeFBlock_Operation

void completeFBlock_Operation()

Gather dependencies from all blocks of this operation to other Operation_FBlock_JgenMdl of the same modul (Java class) and gather the inputs and outputs.

• It is invoked if all blocks of the module are assigned to operations, after GenJava_Class_JgenMdl#sortBlocksToOperations()
• Write dep to other Operation_FBlock in operationBlock FBlock_JgenMdl.stm StatementData_JgenMdl.stms_src.
• Note: This array will be filled in the used Operation_FBlock with the depending outer blocks too from the connections.
• Write inports to inports. If more as one of blocks uses the same inport, it is written only one with its key FBlock_Port_JgenMdl.ixPortInModuleBlock.
• Write outports to outports adequate with ixPortInModuleBlock

fillOperationBlock

private void fillOperationBlock()

genJava_Operation

void genJava_Operation(java.lang.Appendable out,
                       boolean bUpdateOperation)
                throws java.io.IOException

Output the Java code from all blocks of this part.

• All blocks of the module are processed.
• If a module have a FBlock_JgenMdl.stm it is an output Block of a Part and it contains a java part code.
• Only that blocks are used. All other blocks are inner blocks of expressions without own Java code.
• The blocks are assembled in an array, then sorted to its StatementData_JgenMdl#order. The order of the blocks were calculated by part code generation in #addEnds(FBlock_JgenMdl, FBlock_JgenMdl) which invokes #orderToStart(FBlock_JgenMdl, int, int) to store an order number in calculation order.
• The sorted blocks are in the correct order for the java code.
• The Java code will be written to outJava.
