Vis5DTopoForm

public Vis5DTopoForm()

Create a new Vis5DTopoForm

Method Detail

isThisType

public boolean isThisType(String name)

Check to see if the file name might be right for this form.

Specified by:

isThisType in interface FormFileInformer

Parameters:

name - name of the file

Returns:

true if it might be a Vis5D topography file based on the name.

isThisType

public boolean isThisType(byte[] block)

Check to see if the block contains the magic number

Specified by:

isThisType in interface FormFileInformer

Parameters:

block - block of bytes from file

Returns:

true if the first 4 bytes correspond to "TOPO"

getDefaultSuffixes

public String[] getDefaultSuffixes()

Get default suffixes for Vis5D topography files

Specified by:

getDefaultSuffixes in interface FormFileInformer

Returns:

array of suffixes (.v5d, .TOPO)

save

public void save(String id,
                 Data data,
                 boolean replace)
          throws BadFormException,
                 IOException,
                 RemoteException,
                 VisADException

Save a VisAD data object in this form.

Specified by:

save in class FormNode

Parameters:

id - file id

data - Data object to save

replace - true to replace the existing file

Throws:

UnimplementedException - not implemented for this form

BadFormException

IOException

add

public void add(String id,
                Data data,
                boolean replace)
         throws BadFormException

Add data to an existing data object.

Specified by:

add in class FormNode

Parameters:

id - file id

data - Data object to append to

replace - true to replace the existing file

Throws:

BadFormException - not applicable to this form

getForms

public FormNode getForms(Data data)

Return the data forms that are compatible with a data object.

Specified by:

getForms in class FormNode

Parameters:

data - Data object in question

Returns:

null for this Form since it doesn't support save.

open

public DataImpl open(URL url)
              throws BadFormException,
                     VisADException,

Returns a VisAD data object corresponding to a URL pointing to a Vis5D topography file.

Specified by:

open in class FormNode

Parameters:

url - URL pointing to the Vis5D topography

Returns:

A VisAD data object corresponding to the Vis5D topography file.

Throws:

BadFormException - if not a Vis5D topo file.

VisADException - if a problem occurs in core VisAD. Probably a VisAD object couldn't be created.

IOException - if an I/O failure occurs.

open
