class JSUPPORT::JDAQFileReader< T, true >
Template specialisation of JDAQFileReader for DAQ compatible data types.
This class provides for an implementation of the JLANG::JAccessibleObjectIterator interface.
The method JLANG::JAbstractObjectIterator::setObject is overwritten so that the desired object is read from the file which may contain also other objects.
Definition at line 52 of file JDAQFileReader.hh.
◆ pointer_type
◆ JDAQFileReader()
Default constructor.
Definition at line 62 of file JDAQFileReader.hh.
Binary input based on std::istream.
JStreamReader(std::istream &__in)
Constructor.
◆ setObject()
Set object.
- Parameters
-
object | reference to object to be set |
- Returns
- true if set; else false
Reimplemented from JIO::JReaderObjectIterator< T >.
