Member Function Documentation

◆ ReadValue()

virtual std::istream & ReadValue ( std::istream &  instr)
inlineoverridevirtual

Pure virtual because this is specific to the data type to be contained. This should be overridden to read the data from the stream. The value read could be encoded for being read from a file as a single string, or have its own special encoding specific to its underlying type. In the case of attribute strings, this will be the GLS file encoded value. The user is responsible for encoding the value themselves, or using WriteValue which should perform encoding to maintain symmetry.

Parameters
instrThe stream to read from.
Returns
The input stream in its current state.

Implements DistiAttributeBase.

◆ WriteValue()

virtual std::ostream & WriteValue ( std::ostream &  outstr)
inlineoverridevirtual

Pure virtual because this is specific to the data type to be contained. This should be overridden to write the data to the stream. The value written could be encoded for writing to a file as a single string, or have its own special encoding specific to its underlying type. In the case of attribute strings, this will be the GLS file encoded value. The user is responsible for decoding the value themselves, or using ReadValue which should perform decoding to maintain symmetry.

Parameters
outstrThe stream to write to.
Returns
The output stream in its current state.

Implements DistiAttributeBase.
