base class for data array writers
T | Type of the data elements to write |
This is an abstract base class; for an actual implementation look at VTKAsciiDataArrayWriter, VTKBinaryDataArrayWriter, or VTKBinaryAppendedDataArrayWriter.
To create an actual DataArrayWriter, one would usually use an object of class DataArrayWriterFactory.
In the constructor, the actual writer implementation will prepare the stream for writing the data. This usually means writing a "<DataArray>" header to the stream. In the write() method it will write a data element to the stream (this is not true for binaryappended mode however: in this mode write just counts the number of bytes that would be written, the actual writing has to happen later independent of the writer). Finally, in the destructor, the stream is put back in a sane state. That usually means writing something line "</DataArray>".
