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";
});
}
Remarks
Collection member lists
For JavaScript, ResourceQualifierVectorView has the members shown in the member lists. In addition, ResourceQualifierVectorView supports a length property, members of Array.prototype, and using an index to access items.
Enumerating the collection in C# or Microsoft Visual Basic
A ResourceQualifierVectorView is enumerable, so you can use language-specific syntax such as foreach in C# to enumerate the items in the collection. The compiler does the type-casting for you and you won't need to cast to IEnumerable<ResourceQualifier> explicitly. If you do need to cast explicitly, for example if you want to call GetEnumerator, cast to IEnumerable
Properties
Item[Int32] Item[Int32] Item[Int32] Item[Int32]
Gets the element at the specified index in the read-only list.
This member is not implemented in C++T this[int index] { get; }ReadOnly Property Item(index As Integer) As TT this[int index] { get; }
- index
The zero-based index of the element to get.
- Value
- T T T T
The element at the specified index in the read-only list.
Size Size Size Size
Gets the number of ResourceQualifier objects in the view.
public : unsigned int Size { get; }This member is not implemented in C#This member is not implemented in VB.Net// You can use this property in JavaScript.
- Value
- unsigned int uint uint uint
The number of objects in the view.
Methods
First() First() First() First()
Returns an iterator to enumerate the items in the view.
public : IIterator<ResourceQualifier> First()This member is not implemented in C#This member is not implemented in VB.Net// You can use this method in JavaScript.
The iterator. The current position of the iterator is index 0, or the end of the view if the view is empty.
GetAt(UInt32) GetAt(UInt32) GetAt(UInt32) GetAt(UInt32)
Returns the ResourceQualifier at the specified index in the view.
public : ResourceQualifier GetAt(unsigned int index)This member is not implemented in C#This member is not implemented in VB.Net// You can use this method in JavaScript.
- index
- unsigned int UInt32 UInt32 UInt32
The zero-based index of the ResourceQualifier in the view to return.
The ResourceQualifier at the specified index.
GetEnumerator() GetEnumerator() GetEnumerator() GetEnumerator()
Returns an enumerator that iterates through the collection.
This member is not implemented in C++IEnumerator<T> GetEnumerator()Function GetEnumerator As IEnumerator(Of T)IEnumerator<T> GetEnumerator()
An enumerator that can be used to iterate through the collection.
GetMany(UInt32, ResourceQualifier[]) GetMany(UInt32, ResourceQualifier[]) GetMany(UInt32, ResourceQualifier[]) GetMany(UInt32, ResourceQualifier[])
Returns the ResourceQualifier objects that start at the specified index in the view.
public : unsigned int GetMany(unsigned int startIndex, ResourceQualifier[] items)This member is not implemented in C#This member is not implemented in VB.Net// You can use this method in JavaScript.
- startIndex
- unsigned int UInt32 UInt32 UInt32
The zero-based index of the start of the objects in the view to return.
- items
- ResourceQualifier[] ResourceQualifier[] ResourceQualifier[] ResourceQualifier[]
The objects in the view that start at startIndex.
The number of objects returned.
IndexOf(ResourceQualifier, UInt32) IndexOf(ResourceQualifier, UInt32) IndexOf(ResourceQualifier, UInt32) IndexOf(ResourceQualifier, UInt32)
Returns the index of a specified ResourceQualifier in the view.
public : PlatForm::Boolean IndexOf(ResourceQualifier value, unsigned int index)This member is not implemented in C#This member is not implemented in VB.Net// You can use this method in JavaScript.
The ResourceQualifier to find in the set.
- index
- unsigned int UInt32 UInt32 UInt32
The zero-based index of the object, if found. The method returns zero if the object is not found.
A Boolean that is TRUE if the object is found, otherwise FALSE if the object is not found.
