550 std::ostringstream
oss;
Defines basic traits for the ordinal field type.
Encapsulation of the result of a receive (blocking or nonblocking).
Abstract interface for distributed-memory communication.
Simple wrapper class for raw pointers to single objects where no persisting relationship exists.
Smart reference counting pointer class for automatic garbage collection.
RCP(ENull null_arg=null)
Initialize RCP<T> to NULL.
RCP< T > rcp(const boost::shared_ptr< T > &sptr)
Conversion function that takes in a boost::shared_ptr object and spits out a Teuchos::RCP object.
bool is_null() const
Returns true if the underlying pointer is null.
T * getRawPtr() const
Get the raw C++ pointer to the underlying object.
Implementation of CommStatus for a serial communicator.
OrdinalType getSourceRank()
The source rank that sent the message (must be zero).
OrdinalType getTag()
The tag of the received message.
SerialCommStatus()
Default constructor.
Concrete serial communicator subclass.

#define TEUCHOS_TEST_FOR_EXCEPT(throw_exception_test)
This macro is designed to be a short version of TEUCHOS_TEST_FOR_EXCEPTION() that is easier to call.
#define TEUCHOS_TEST_FOR_EXCEPTION(throw_exception_test, Exception, msg)
Macro for throwing an exception with breakpointing to ease debugging.
The Teuchos namespace contains all of the classes, structs and enums used by Teuchos,...
TEUCHOS_DEPRECATED RCP< T > rcp(T *p, Dealloc_T dealloc, bool owns_mem)
Deprecated.
static std::string name()
Returns name of this ordinal type.
