Method Summary

boolean	hasPathPartForKey(String key) Determines if a path part exists for a given key.
boolean	hasPathPartForKey(String key, boolean caseInsensitive) Determines if a path part exists for a given key with the option of performing a case insensitve comparison.
String	pathPartForKey(String key) Gets a path part for a given key.
String	pathPartForKeyWithDefault(String key, String defaultValue) Gets a path part for a given key, returning the default value if nothing was specified.
String	pathPartForKeyWithDefault(String key, String defaultValue, boolean caseInsensitiveCompare) Gets a path part for a given key, returning the default value if nothing was specified.
NSArray	pathParts() The path parts of a request correspond to to all of the pieces between the request handler key and the class name.
NSDictionary	pathPartsByKeys() Given an array of path parts (foo=food, bar=baz, gee) this will produce a dictionary of the form: { foo=food; bar=baz; }.
NSDictionary	pathPartsByKeysCaseInsensitive() Same method as pathPartsByKeys except all of the keys have been down cased, ie for path parts (Foo=food, bAr=baz, gee) this will give a dictionary of the form { foo=food; bar=baz; }.

Constructor Detail

ERXPathDirectAction

public ERXPathDirectAction(WORequest aRequest)

Just calls super.

Method Detail

pathParts

public NSArray pathParts()

The path parts of a request correspond to to all of the pieces between the request handler key and the class name. For instance given the direct action path /WebObjects/MyApp.woa/wpa/foo/bar/MyDirectActionClass/action would produce the path parts (foo, bar).

Returns:

array of path parts for the given request

pathPartsByKeys

public NSDictionary pathPartsByKeys()

Given an array of path parts (foo=food, bar=baz, gee) this will produce a dictionary of the form: { foo=food; bar=baz; }. In the current for this method does not handle multiple keys with the same name.

Returns:

path parts broken down by key

pathPartsByKeysCaseInsensitive

public NSDictionary pathPartsByKeysCaseInsensitive()

Same method as pathPartsByKeys except all of the keys have been down cased, ie for path parts (Foo=food, bAr=baz, gee) this will give a dictionary of the form { foo=food; bar=baz; }.

Returns:

path parts by case insensitive key

hasPathPartForKey

public boolean hasPathPartForKey(String key)

Determines if a path part exists for a given key.

Parameters:

key - path part key

Returns:

if a path was specified

hasPathPartForKey

public boolean hasPathPartForKey(String key,
                                 boolean caseInsensitive)

Determines if a path part exists for a given key with the option of performing a case insensitve comparison.

Parameters:

key - path part key

caseInsensitive - key comparison should be case sensitive

Returns:

if a path was specified

pathPartForKey

public String pathPartForKey(String key)

Gets a path part for a given key.

Parameters:

key - path part key

Returns:

path part for the key

pathPartForKeyWithDefault

public String pathPartForKeyWithDefault(String key,
                                        String defaultValue)

Gets a path part for a given key, returning the default value if nothing was specified.

Parameters:

key - path part key

defaultValue - default value

Returns:

path part for the key or the default value

pathPartForKeyWithDefault

public String pathPartForKeyWithDefault(String key,
                                        String defaultValue,
                                        boolean caseInsensitiveCompare)

Gets a path part for a given key, returning the default value if nothing was specified. Adds the option for a case insensitive comparison.

Parameters:

key - path part key

defaultValue - default value

caseInsensitiveCompare - key comparison should ignore case

Returns:

path part for the key or the default value
