Hello, i'm jskang

I am currently studying OpenFOAM code and reviewing icoFoam.c step by step. However, I have encountered a part that I cannot understand, so I am posting this question in the community. I am studying using ESI version v2312, and I am looking at the following code in IOField.C. The part I do not understand is is >> *this. I assume it means transferring the data from the Istream instance (is) to the IOField instance. Also, I expect that the >> is an operator overloaded for IOField. When I look for this operator definition, I see that >> is defined in Istream, but with different arguments, so it doesn’t seem to be the correct one. Could you tell me where the >> operator for this case is defined?

// * * * * * * * * * * * * * Private Member Functions * * * * * * * * * * * //

template<class Type>
void Foam::IOField<Type>::readFromStream(const bool readOnProc)
{
Istream& is = readStream(typeName, readOnProc);

if (readOnProc)
{
is >> *this;
}
close();
}
