Class Evchain_FBcl

java.lang.Object

org.vishia.fbcl.fblock.Evchain_FBcl

public class Evchain_FBcl
extends java.lang.Object

This class contains detail information for code generation of a module. It is mainly referenced from Module_FBcl.evChains.

• The nr is equal the position in the Module_FBcl.evChains.

Field Detail

nr

public final int nr

Number, index of this Evchain in the list in the module.

evStart

public final Evin_FBcl evStart

The start event inside the chain. Note: An event can have more as one operations (=^ more as one chains inside the module). Note: The evStart is always an event of a FBlock inside the module.

ixFirstOper

private int ixFirstOper

The index of the operation in evStart: EvinoutType_FBcl#operations for this event chain. If -1 either there it is not detected yet or it has only one operation.

evList

private java.util.List<Evchain_FBcl.EvCurr> evList

ixEvcurrWithStatements

private int ixEvcurrWithStatements

Index in evList of the last evin which should produce a statement either for the FBlock itself or to feed a variable. The following FBlocks may be combinatoric.

evoutPin

EvoutType_FBcl evoutPin

The event out pin of the module if it is reached with this evChain, null if the evChain forks internally.

XXXmDin

private transient long XXXmDin

The current Input aus bits while building the chain. If a Dout_FBcl.isLocalVar() is detected, it will be stored as the Operation_FBcl#mUsedDinEvOper} of this chain. Elsewhere it will be stored on the DoutType_FBcl#mUsedInputs of the output.

operation

public Operation_FBcl operation

The associated operation for the chain. The operation contains the bits for triggered events, driven outputs of this chain as property of the module (the FBlock_Type_FBcl. This operation is referenced from the Event pins of the interface FBlock of the module too. It contains the calling code gen rule if the module is used anywhere.

mPrevEvchain

private long mPrevEvchain

bTrgFromStmn

public final boolean bTrgFromStmn

if true then this evChain comes from a StateMachine trigger.
