public boolean dspMatch(String location,
                        dap4.core.util.DapContext context)
```
    A path is file if it has no base protocol or is file:
    
    Parameters:
    
    location - file:/ or possibly an absolute path
    
    context - Any parameters that may help to decide.
    
    Returns:
    
    true if this path appears to be processible by this DSP
  - close
```
public void close()
```
    Specified by:
    
    close in interface dap4.core.data.DSP
    
    Specified by:
    
    close in class AbstractDSP
  - open
```
public FileDSP open(String filepath)
             throws dap4.core.util.DapException
```
    Description copied from class: AbstractDSP
    
    "open" a reference to a data source and return the DSP wrapper.
    
    Specified by:
