Class ResourceMap

public class ResourceMap extends java.lang.Object
A read-only encapsulation of one or more ResourceBundles that adds automatic string conversion, support for field and Swing component property injection, string resource variable substitution, and chaining.ResourceMaps are typically obtained with the
ApplicationContext
getResourceMap
method which lazily creates per Application, package, and class ResourceMaps that are linked together with the ResourceMap parent property.An individual ResourceMap provides read-only access to all of the resources defined by the ResourceBundles named when the ResourceMap was created as well as all of its parent ResourceMaps. Resources are retrieved with the getObject method which requires both the name of the resource and its expected type. The latter is used to convert strings if neccessary. Converted values are cached. As a convenience, getObject wrapper methods for common GUI types, like getFont, and getColor, are provided.
The getObject method scans raw string resource values for ${resourceName} variable substitutions before performing string conversion. Variables named this way can refer to String resources defined anywhere in their ResourceMap or any parent ResourceMap. The special variable ${null} means that the value of the resource will be null.
ResourceMaps can be used to "inject" resource values into Swing component properties and into object fields. The injectComponents method uses Component names (
Component.setName(java.lang.String)
) to match resources names with properties. The injectFields method sets fields that have been tagged with the @Resource annotation to the value of resources with the same name.- See Also:

ResourceMap
public ResourceMap(ResourceMap parent, java.lang.ClassLoader classLoader, java.util.List<java.lang.String> bundleNames)
Creates a ResourceMap that contains all of the resources defined in the namedResourceBundle
s as well as (recursively) the parent ResourceMap. The parent may be null. Typically just one ResourceBundle is specified however one might name additional ResourceBundles that contain platform or Swing look and feel specific resources. When multiple bundles are named, a resource defined in bundlen will overide the same resource defined in bundles0..n-1. In other words bundles named later in the argument list take precendence over the bundles named earlier.ResourceBundles are loaded with the specified ClassLoader. If classLoader is null, an IllegalArgumentException is thrown.
At least one bundleName must be specified and all of the bundleNames must be non-empty strings, or an IllegalArgumentException is thrown. The bundles are listed in priority order, highest priority first. In other words, resources in the the first ResourceBundle named first, shadow resources with the same name later in the list.
All of the bundleNames must share a common package prefix. The package prefix implicitly specifies the resources directory (see
getResourcesDir()
). For example, the resources directory for bundle names "myapp.resources.foo" and "myapp.resources.bar", would be "myapp/resources/". If bundle names don't share a common package prefix, then an IllegalArgumentException is thrown.- Parameters:
parent
- parent ResourceMap or nullclassLoader
- the ClassLoader to be used to load the ResourceBundlebundleNames
- names of the ResourceBundle to be loaded- Throws:
java.lang.IllegalArgumentException
- if classLoader or any bundleName is null, if no bundleNames are specified, if any bundleName is an empty (zero length) String, or if all of the bundleNames don't have a common package prefix- See Also:

getObject
public java.lang.Object getObject(java.lang.String key, java.lang.Class type)
Returns the value of the resource named key, or null if no resource with that name exists. A resource exists if it's defined in this ResourceMap or (recursively) in the ResourceMap's parent.String resources may contain variables that name other resources. Each ${variable-key} variable is replaced with the value of a string resource named variable-key. For example, given the following resources:
Application.title = My Application ErrorDialog.title = Error: ${application.title} WarningDialog.title = Warning: ${application.title}
The value of "WarningDialog.title" would be "Warning: My Application". To include "${" in a resource, insert a backslash before the "$". For example, the value of escString in the example below, would be "${hello}":escString = \\${hello}
Note that, in a properties file, the backslash character is used for line continuation, so we've had to escape that too. If the value of a resource is the special variable ${null}, then the resource will be removed from this ResourceMap.The value returned by getObject will be of the specified type. If a string valued resource exists for key, and type is not String.class, the value will be converted using a ResourceConverter and the ResourceMap entry updated with the converted value.
If the named resource exists and an error occurs during lookup, then a ResourceMap.LookupException is thrown. This can happen if string conversion fails, or if resource parameters can't be evaluated, or if the existing resource is of the wrong type.
An IllegalArgumentException is thrown if key or type are null.
- Parameters:
key
- resource nametype
- resource type- Throws:
ResourceMap.LookupException
- if an error occurs during lookup or string conversionjava.lang.IllegalArgumentException
- if key or type are null- See Also:

,ResourceMap.LookupException
-
getString
public java.lang.String getString(java.lang.String key, java.lang.Object... args)
If no arguments are specified, return the String value of the resource named key. This is equivalent to calling getObject(key, String.class) If arguments are provided, then the type of the resource named key is assumed to beformat
string, which is applied to the arguments if it's non null. For example, given the following resourceshello = Hello %s
then the value of getString("hello", "World") would be "Hello World".- Returns:

injectComponent
public void injectComponent(java.awt.Component target)
Set each property in target to the value of the resource named componentName.propertyName, where componentName is the value of the target component's name property, i.e. the value of target.getName(). The type of the resource must match the type of the corresponding property. Properties that aren't defined by a resource aren't set.For example, given a button configured like this:
myButton = new JButton(); myButton.setName("myButton");
And a ResourceBundle properties file with the following resources:myButton.text = Hello World myButton.foreground = 0, 0, 0 myButton.preferredSize = 256, 256
Then injectComponent(myButton) would initialize myButton's text, foreground, and preferredSize properties to Hello World, new Color(0,0,0), and new Dimension(256,256) respectively.This method calls
getObject(java.lang.String, java.lang.Class)
to look up resources and it usesIntrospector.getBeanInfo(java.lang.Class<?>)
to find the target component's properties.If target is null an IllegalArgumentException is thrown. If a resource is found that matches the target component's name but the corresponding property can't be set, an (unchecked)
ResourceMap.PropertyInjectionException
is thrown.- Parameters:
target
- the Component to inject- Throws:
ResourceMap.LookupException
- if an error occurs during lookup or string conversionResourceMap.PropertyInjectionException
- if a property specified by a resource can't be setjava.lang.IllegalArgumentException

to each Component in the hierarchy with root root.- Parameters:
root
- the root of the component hierarchy- Throws:
ResourceMap.PropertyInjectionException
- if a property specified by a resource can't be setjava.lang.IllegalArgumentException
- if target is null- See Also:
injectComponent(java.awt.Component)
-
injectFields
public void injectFields(java.lang.Object target)
Set each field with a @Resource annotation in the target object, to the value of a resource whose name is the simple name of the target class followed by "." followed by the name of the field. If the key @Resource parameter is specified, then a resource with that name is used instead. Array valued fields can also be initialized with resources whose names end with "[index]". For example:class MyClass { @Resource String sOne; @Resource(key="sTwo") String s2; @Resource int[] numbers = new int[2]; }
Given the previous class and the following resource file:MyClass.sOne = One sTwo = Two MyClass.numbers[0] = 10 MyClass.numbers[1] = 11
Then injectFields(new MyClass()) would initialize the MyClass sOne field to "One", the s2 field to "Two", and the two elements of the numbers array to 10 and 11.If target is null an IllegalArgumentException is thrown. If an error occurs during resource lookup, then an unchecked LookupException is thrown. If a target field marked with @Resource can't be set, then an unchecked InjectFieldException is thrown.
- Parameters:
target
- the object whose fields will be initialized- Throws:
ResourceMap.LookupException
- if an error occurs during lookup or string conversionResourceMap.InjectFieldException
