Detailed Description

The base class for classes that act internally like OutputStream to convert data.

Description
If you use the SetStream function to set an output stream and use the OutputStream interface to write the data, the data is converted in an internal process and written to the output stream.

Member Function Documentation

nn::nlib::OutputConverterStream::GetStream ( ) const
inlinenoexcept

Gets the input stream that will be the base stream.

Returns
Returns the pointer to the output stream.

Definition at line 34 of file OutputConverterStream.h.

nn::nlib::OutputConverterStream::SetStream ( OutputStream ostr)
noexcept

Sets an output stream as the base stream.

Parameters
[in]ostrA pointer to the base string.
Return values
0No error has occurred.
EEXISTThe stream is already set.
EINVALostr was set to NULL.
EBADFThe SetTransform function has not executed.
ENOMEMAllocation of working memory failed.
