javax.activation.CommandMap — clojure-interop/javax.activation 1.0.4

The CommandMap class provides an interface to a registry of command objects available in the system. Developers are expected to either use the CommandMap implementation included with this package (MailcapCommandMap) or develop their own. Note that some of the methods in this class are abstract.

*get-default-command-map clj

(*get-default-command-map)

Get the default CommandMap.

In cases where a CommandMap instance has been previously set to some value (via setDefaultCommandMap) return the CommandMap.

In cases where no CommandMap has been set, the CommandMap creates an instance of MailcapCommandMap and set that to the default, returning its value.

returns: the CommandMap - javax.activation.CommandMap

*set-default-command-map clj

(*set-default-command-map command-map)

Set the default CommandMap. Reset the CommandMap to the default by calling this method with null.

command-map - The new default CommandMap. - javax.activation.CommandMap

throws: java.lang.SecurityException - if the caller doesn't have permission to change the default

->command-map clj

(->command-map)

Constructor.

create-data-content-handler clj

(create-data-content-handler this mime-type)

(create-data-content-handler this mime-type ds)

Locate a DataContentHandler that corresponds to the MIME type. The mechanism and semantics for determining this are determined by the implementation of the particular CommandMap.

The DataSource provides extra information, such as the file name, that a CommandMap implementation may use to further refine the choice of DataContentHandler. The implementation in this class simply calls the createDataContentHandler method that ignores this argument.

mime-type - the MIME type - java.lang.String ds - a DataSource for the data - javax.activation.DataSource

returns: the DataContentHandler for the MIME type - javax.activation.DataContentHandler

get-all-commands clj

(get-all-commands this mime-type)

(get-all-commands this mime-type ds)

Get all the available commands for this type. This method should return all the possible commands for this MIME type.

The DataSource provides extra information, such as the file name, that a CommandMap implementation may use to further refine the list of commands that are returned. The implementation in this class simply calls the getAllCommands method that ignores this argument.

mime-type - the MIME type - java.lang.String ds - a DataSource for the data - javax.activation.DataSource

returns: the CommandInfo objects representing all the commands. - javax.activation.CommandInfo[]

get-command clj

(get-command this mime-type cmd-name)

(get-command this mime-type cmd-name ds)

Get the default command corresponding to the MIME type.

The DataSource provides extra information, such as the file name, that a CommandMap implementation may use to further refine the command that is chosen. The implementation in this class simply calls the getCommand method that ignores this argument.

mime-type - the MIME type - java.lang.String cmd-name - the command name - java.lang.String ds - a DataSource for the data - javax.activation.DataSource

returns: the CommandInfo corresponding to the command. - javax.activation.CommandInfo

get-mime-types clj

(get-mime-types this)

Get all the MIME types known to this command map. If the command map doesn't support this operation, null is returned.

returns: array of MIME types as strings, or null if not supported - java.lang.String[]

get-preferred-commands clj

(get-preferred-commands this mime-type)

(get-preferred-commands this mime-type ds)

Get the preferred command list from a MIME Type. The actual semantics are determined by the implementation of the CommandMap.

The DataSource provides extra information, such as the file name, that a CommandMap implementation may use to further refine the list of commands that are returned. The implementation in this class simply calls the getPreferredCommands method that ignores this argument.

mime-type - the MIME type - java.lang.String ds - a DataSource for the data - javax.activation.DataSource

returns: the CommandInfo classes that represent the command Beans. - javax.activation.CommandInfo[]
