ResourceCandidate class

Applies to Windows and Windows Phone

Represents a single possible value for a given NamedResource, the qualifiers associated with that resource, and how well those qualifiers match the context against which it was resolved.

Syntax


public sealed class ResourceCandidate

Attributes

[MarshalingBehavior(Agile)]
[Version(0x06020000)]

Members

The ResourceCandidate class has these types of members:

Methods

The ResourceCandidate class has these methods. With C#, Visual Basic, and C++, it also inherits methods from the Object class.

MethodDescription
GetQualifierValue Returns the value of a qualifier, given its name.
GetValueAsFileAsync Asynchronously returns a StorageFile that accesses the value of this ResourceCandidate. This only works on certain types of ResourceCandidates that are files.

 

Properties

The ResourceCandidate class has these properties.

PropertyAccess typeDescription

IsDefault

Read-onlyIndicates whether this ResourceCandidate can be used as a default fallback value for any context.

IsMatch

Read-onlyIndicates whether this ResourceCandidate matched the ResourceContext against which it was evaluated.

IsMatchAsDefault

Read-onlyIndicates whether this ResourceCandidate matched the ResourceContext against which it was evaluated as a result of being a default fallback value or mixed match with default fallback (that is, a match in relation to some qualifiers but using default fallback values for other qualifiers), and not as a true match.

Qualifiers

Read-onlyGets the qualifiers associated with this ResourceCandidate.

ValueAsString

Read-onlyGets the value of this ResourceCandidate, expressed as a string.

 

Examples

This example is based on scenario 13 of the Application resources and localization sample. See the sample for the more complete solution.


// Create a ResourceContext.
var resourceContext = new Windows.ApplicationModel.Resources.Core.ResourceContext();

// Set the specific context for lookup of resources.
var qualifierValues = resourceContext.qualifierValues;
qualifierValues["language"] = "en-US";
qualifierValues["contrast"] = "standard";
qualifierValues["scale"] = "140";
qualifierValues["homeregion"] = "021"; // Northern America

// Resources actually reside within Scenario13 Resource Map.
var resourceIds = [
    '/Scenario13/languageOnly',
    '/Scenario13/scaleOnly',
    '/Scenario13/contrastOnly',
    '/Scenario13/homeregionOnly',
    '/Scenario13/multiDimensional',
];

var output = { str: "" };
resourceIds.forEach(function (resourceId) {
    renderNamedResource(resourceId, resourceContext, output);
});

function renderNamedResource(resourceId, resourceContext, output) {
    output.str += "Resource ID " + resourceId + ":\n";
    // Lookup the resource in the mainResourceMap (the one for this package).
    var namedResource = Windows.ApplicationModel.Resources.Core.ResourceManager.current.mainResourceMap.lookup(resourceId);

    // Return a ResourceCandidateVectorView of all possible resources candidates
    // resolved against the context in order of appropriateness.
    var resourceCandidates = namedResource.resolveAll(resourceContext);

    resourceCandidates.forEach(function (candidate, index) {
        renderCandidate(candidate, index, output);
    });
    output.str += "\n";
}

function renderCandidate(candidate, index, output) {
    // Get all the various qualifiers for the candidate (such as language, scale, contrast).
    candidate.qualifiers.forEach(function (qualifier) {
        output.str += "qualifierName: " + qualifier.qualifierName + "\n";
        output.str += "qualifierValue: " + qualifier.qualifierValue + "\n";
        output.str += "isDefault: ";
        output.str += (qualifier.isDefault) ? "true\n" : "false\n";
        output.str += "isMatch: ";
        output.str += (qualifier.isMatch) ? "true\n" : "false\n";
        output.str += "score: " + qualifier.score + "\n";
        output.str += "\n";
    });
}
