Example 1 with CachedValueProvider

use of com.intellij.psi.util.CachedValueProvider in project android by JetBrains.

the class AndroidXmlSchemaProvider method getSchema.

@Override
public XmlFile getSchema(@NotNull @NonNls String url, @Nullable final Module module, @NotNull PsiFile baseFile) {
    if (module == null || AndroidFacet.getInstance(module) == null)
        return null;
    Map<String, CachedValue<XmlFile>> descriptors = module.getUserData(DESCRIPTORS_MAP_IN_MODULE);
    if (descriptors == null) {
        descriptors = new THashMap<String, CachedValue<XmlFile>>();
        module.putUserData(DESCRIPTORS_MAP_IN_MODULE, descriptors);
    }
    CachedValue<XmlFile> reference = descriptors.get(url);
    if (reference != null) {
        return reference.getValue();
    }
    CachedValuesManager manager = CachedValuesManager.getManager(module.getProject());
    reference = manager.createCachedValue(new CachedValueProvider<XmlFile>() {

        @Override
        public Result<XmlFile> compute() {
            final URL resource = AndroidXmlSchemaProvider.class.getResource("android.xsd");
            final VirtualFile fileByURL = VfsUtil.findFileByURL(resource);
            XmlFile result = (XmlFile) PsiManager.getInstance(module.getProject()).findFile(fileByURL).copy();
            return new Result<XmlFile>(result, PsiModificationTracker.MODIFICATION_COUNT);
        }
    }, false);
    descriptors.put(url, reference);
    return reference.getValue();

Example 2 with CachedValueProvider

use of com.intellij.psi.util.CachedValueProvider in project kotlin by JetBrains.

the class ProjectStructureUtil method getCachedPlatformForModule.

@NotNull

    CachedValue<TargetPlatform> result = module.getUserData(PLATFORM_FOR_MODULE);
    if (result == null) {
        result = CachedValuesManager.getManager(module.getProject()).createCachedValue(new CachedValueProvider<TargetPlatform>() {

            @Override

                TargetPlatform configuredInFacet = getPlatformConfiguredInFacet(module);
                TargetPlatform platform = configuredInFacet != null ? configuredInFacet : hasJsStandardLibraryInDependencies(module) ? JsPlatform.INSTANCE : JvmPlatform.INSTANCE;
                return Result.create(platform, ProjectRootModificationTracker.getInstance(module.getProject()));
            }
        }, false);
        module.putUserData(PLATFORM_FOR_MODULE, result);
    }
    return result.getValue();
}

Example 3 with CachedValueProvider

use of com.intellij.psi.util.CachedValueProvider in project android by JetBrains.

the class ManifestInnerClass method getFields.

@NotNull
@Override

    if (myFieldsCache == null) {
        myFieldsCache = CachedValuesManager.getManager(getProject()).createCachedValue(new CachedValueProvider<PsiField[]>() {

            @Override
            public Result<PsiField[]> compute() {
                final Manifest manifest = myFacet.getManifest();
