Detailed Description

A class representing a collection of resource information pertaining to a given locale.

A resource bundle provides a way of accessing locale- specfic information in a data file. You create a resource bundle that manages the resources for a given locale and then ask it for individual resources.

Resource bundles in ICU4C are currently defined using text files which conform to the following BNF definition. More on resource bundle concepts and syntax can be found in the Users Guide.

The ResourceBundle class is not suitable for subclassing.

Constructor & Destructor Documentation

◆ ResourceBundle() [1/6]

icu::ResourceBundle::ResourceBundle	(	const UnicodeString &	packageName,
		const Locale &	locale,
		UErrorCode &	err
	)

Constructor.

Parameters

packageName	The packageName and locale together point to an ICU udata object, as defined by `udata_open( packageName, "res", locale, err)` or equivalent. Typically, packageName will refer to a (.dat) file, or to a package registered with udata_setAppData(). Using a full file or directory pathname for packageName is deprecated.
locale	This is the locale this resource bundle is for. To get resources for the French locale, for example, you would create a ResourceBundle passing Locale::FRENCH for the "locale" parameter, and all subsequent calls to that resource bundle will return resources that pertain to the French locale. If the caller doesn't pass a locale parameter, the default locale for the system (as returned by Locale::getDefault()) will be used.
err	The Error Code. The UErrorCode& err parameter is used to return status information to the user. To check whether the construction succeeded or not, you should check the value of U_SUCCESS(err). If you wish more detailed information, you can check for informational error results which still indicate success. U_USING_FALLBACK_WARNING indicates that a fall back locale was used. For example, 'de_CH' was requested, but nothing was found there, so 'de' was used. U_USING_DEFAULT_WARNING indicates that the default locale data was used; neither the requested locale nor any of its fall back locales could be found.

◆ ResourceBundle() [2/6]

icu::ResourceBundle::ResourceBundle	(	const UnicodeString &	packageName,
		UErrorCode &	err
	)

Construct a resource bundle for the default bundle in the specified package.

Parameters

packageName	The packageName and locale together point to an ICU udata object, as defined by `udata_open( packageName, "res", locale, err)` or equivalent. Typically, packageName will refer to a (.dat) file, or to a package registered with udata_setAppData(). Using a full file or directory pathname for packageName is deprecated.
err	A UErrorCode value

Standard constructor, constructs a resource bundle for the locale-specific bundle in the specified package.

Parameters

packageName	The packageName and locale together point to an ICU udata object, as defined by `udata_open( packageName, "res", locale, err)` or equivalent.
