DefaultFamily

public DefaultFamily(java.lang.String name,

Construct a family of the supported VisAD datatype Forms, with a netCDF form that converts char to Text if netcdfText flag is set.

Method Detail

addFormToList

public static void addFormToList(FormNode form)
                          throws java.lang.ArrayIndexOutOfBoundsException

Add a Form to the list of supported VisAD datatype Forms. Forms are added to the front of the list, which means that they will take precedence over existing Forms. If, for example, an added Form claims to open files ending in .gif, it will supersede the standard GIFForm. If the added form discovers that it cannot handle a file, it can simply throw an exception and DefaultFamily will pass the file onto the next Form in the list, so any superseded Form will still be able to open the file.

Throws:

java.lang.ArrayIndexOutOfBoundsException - If there is no more room in the list.
