Field Detail

theFileTypes

public static java.util.Hashtable theFileTypes
Lookup table (name->class) for different file types

Constructor Detail

FileMap

public FileMap(java.lang.String fname,
               java.lang.String ftype,
               int period)
Creates a FileMap

Parameters:
fname - the file name
ftype - the file type
period - The period (in seconds) to perform a reload on the file: If set to 0, no reload will take place. If set to -1, a "stat" operation will be performed on the file at each lookup, to determine whether the modify date has changed and a reload is necessary
