Detailed Description

Interface to access the behavior model of TTA operations.

This abstract class that is inherited by the custom operation behavior classes. Instances of user defined OperationBehavior derived classes are loaded run-time from dynamic library modules (plugins).

areValid()

bool OperationBehavior::areValid ( const InputOperandVector &  inputs, const OperationContext &  context  ) const

virtual

The default implementation of input operand validation.

This always return true. This is meant to be overridden in derived classes when necessary.

Reimplemented in OperationDAGBehavior.

Definition at line 96 of file OperationBehavior.cc.

                                     {
 
    return true;
}

Referenced by Operation::areValid().

canBeSimulated()

bool OperationBehavior::canBeSimulated ( ) const

virtual

If behavior can be simulated.

Returns

true If simulation of behavior is possible.

Reimplemented in OperationDAGBehavior, and OperationBehaviorProxy.

Definition at line 162 of file OperationBehavior.cc.

                                        {
    return true;
}

Referenced by OperationPimpl::canBeSimulated().

createState()

void OperationBehavior::createState ( OperationContext &  context ) const

virtual

Creates the instance of operation state for this operation and adds it to its operation context.

By default this function does nothing (assumes that the operation has no state). If the operation context already contains the required operation state instance, nothing is done.

Parameters

context

The operation context to add the state to.

Reimplemented in OperationDAGBehavior, and OperationBehaviorProxy.

Definition at line 127 of file OperationBehavior.cc.

                                                      {
}

Referenced by SimulateDialog::createState(), OperationPimpl::createState(), and OsalInterpreter::operation().

deleteState()

void OperationBehavior::deleteState ( OperationContext &  context ) const

virtual

Deletes the instance of operation state for this operation from its operation context.

By default this function does nothing (assumes that the operation has no state). If the operation context does not contain the required operation state instance, nothing is done.

Parameters

context

The operation context to delete the state from.

Reimplemented in OperationDAGBehavior, and OperationBehaviorProxy.

Definition at line 141 of file OperationBehavior.cc.

                                                      {
}

Referenced by OperationPimpl::deleteState(), CmdReset::execute(), SimulateDialog::onReset(), and SimulateDialog::~SimulateDialog().

simulateTrigger()

bool OperationBehavior::simulateTrigger ( SimValue **  io, OperationContext &  context  ) const

pure virtual

Simulates the process of starting the execution of an operation.

Clients should invoke isTriggerLocking() before any attempt to call simulateTrigger() in current clock cycle. By default, an operation invocations are successful.

Parameters

io	The input operands and the results of the operation.
context	The operation context affecting the operation results.

Returns

bool True if all values could be computed, false otherwise.

Exceptions

Exception

Depends on the implementation.

Implemented in OperationDAGBehavior, OperationBehaviorProxy, and NullOperationBehavior.

                             {
    return true;
}

stateName()

const char * OperationBehavior::stateName ( ) const

virtual

Returns the name of the state of this operation behavior.

By default returns an empty string which denotes that there is no state.

Returns

The state name for this operation behavior.

Reimplemented in OperationDAGBehavior.

Definition at line 152 of file OperationBehavior.cc.

                                   {
    return "";
}

writeOutput()

void OperationBehavior::writeOutput ( const char *  text ) const

virtual

Writes text to the output stream specified

Parameters

text	text to be written to the output stream

Definition at line 110 of file OperationBehavior.cc.

                            {
    OperationGlobals::outputStream() << text;
