}
|
| private void | appendPrefCmdsToList(java.util.Map cmdHash, java.util.List cmdList)Put the commands that are in the hash table, into the list.

|
| private boolean | checkForVerb(java.util.List cmdList, java.lang.String verb)Check the cmdList to see if this command exists, return
true if the verb is there.

| public synchronized java.lang.String[] | getNativeCommands(java.lang.String mimeType)Get the native commands for the given MIME type.
Returns an array of strings where each string is
an entire mailcap file entry. The application
will need to parse the entry to extract the actual
command as well as any attributes it needs. See
RFC 1524
for details of the mailcap entry syntax. Only mailcap
entries that specify a view command for the specified
MIME type are returned.

| public synchronized javax.activation.CommandInfo[] | getPreferredCommands(java.lang.String mimeType)Get the preferred command list for a MIME Type. The MailcapCommandMap
searches the mailcap files as described above under

The result of the search is a proper subset of available
commands in all mailcap files known to this instance of
MailcapCommandMap. The first entry for a particular command
is considered the preferred command.
