Detailed Description

Derived from DistiAttributeString, the only difference is that it reads and writes encoded strings instead of clear strings.

Member Function Documentation

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

virtual

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.

Reimplemented from DistiAttributeString.

virtual std::string ValueString ( )

virtual

Returns the std::string version of the attribute data. Here in the base class it uses WriteValue() If this particular attribute's underlying type is a string, this returns the unencoded value, suitable for users. If a file encoded value is required, call WriteValue instead.

Reimplemented from DistiAttributeBase.

virtual void ValueString ( const std::string &  s )

virtual

Sets the value from a std::string argument. Here in the base class it uses ReadValue() If this particular attribute's underlying type is a string, this should not be set to an encoded value. If needing to set from an encoded value, call ReadValue instead.

Reimplemented from DistiAttributeBase.

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

virtual

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.
