DtTaskStmt& DtTaskStmt::operator= ( const DtTaskStmt & orig )

assignment operator

virtual DtSimStatement* DtTaskStmt::clone ( DtReaderWriterRegistry * parentRegistry = NULL ) const

virtual

virtual copy constructor

Implements DtSimStatement.

virtual int DtTaskStmt::type ( ) const

virtual

Returns DtTaskStatementType (defined in simStmtTypes.h)

Implements DtSimStatement.

virtual void DtTaskStmt::execute ( DtPlan & planContext )

virtual

Execute the current statement and make any changes to the Plan state as appropriate.

Implements DtSimStatement.

virtual DtString DtTaskStmt::stringRep ( int subBlockIndex = DtSR_STMT ) const

virtual

Get a readable string representation of this Task statement.

The subBlockIndex argument indicates which stringRep to get if this statement could have sub-blocks. Since a Task statement cannot have sub-blocks, a useful string representation will only be returned if the subBlockIndex argument has the value DtSimStatement::DtSR_STMT. See the documentation for DtSimStatement::stringRep for more details.

Implements DtSimStatement.

virtual DtSimTask* DtTaskStmt::task ( ) const

virtual

Get the current Task.

virtual void DtTaskStmt::setTask ( DtSimTask * arg )

virtual

Set the Task (this will clone() its own copy).

virtual void DtTaskStmt::putSelf	(	FILE *	fp,
		int	indentLevel = `0`,
		bool	writeUnspecified = `false`,
		const DtFilename &	path = `DtReaderWriter::appPath()`
	)

virtual

Note: Task statements override putSelf and getSelf so that they can avoid an extra level of nesting in the save file.

DtReaderWriter member function that writes the task as if it were a statement object itself. It calls DtSimTask::putself().

Reimplemented from DtReaderWriter.

virtual void DtTaskStmt::getSelf	(	DtlObjPtr	args,
		const DtFilename &	searchPath,
		const DtVariableBindingsList &	variableBindings
	)

virtual

DtReaderWriter member function that reads the task as if it were a statement object itself.

It calls DtSimTask::createTask().

Reimplemented from DtReaderWriter.

virtual int DtTaskStmt::netRepSize ( ) const

virtual

Returns the size of the full network representation.

Reimplemented from DtSimStatement.

virtual bool DtTaskStmt::setFromNet	(	const char *	contentBuffer,
		unsigned	contentSize
	)

virtual

Fills in the request from the network buffer.

Reimplemented from DtSimStatement.

virtual bool DtTaskStmt::setToNet ( )

virtual

Fills in the network buffer (created by base class sim statement) with the task contents.
