Class DDSParser

shlex.shlex --+    
              |    
     BaseParser --+
                  |
                 DDSParser

A parser for Dataset Descriptor Structure.

First we create a dataset and get its DDS:

>>> dataset = DatasetType(name='test')
>>> dataset['a'] = BaseType(name='a', data=1)
>>> from dap.server import SimpleHandler
>>> headers, output = SimpleHandler(dataset).dds()
>>> dds = ''.join(output)
>>> print dds
Dataset {
    Int32 a;
} test;
<BLANKLINE>

Now we try to parse it. We'll get a second dataset that should have the same DDS:

>>> dataset2 = DDSParser(dds, '').parse()
>>> headers, output = SimpleHandler(dataset2).dds()
>>> print ''.join(output)
Dataset {
    Int32 a;
} test;
<BLANKLINE>

QED.
