Examples with Singleton com.google.inject.Singleton used on opensource projects

Example 61 with Singleton

use of com.google.inject.Singleton in project ovirt-engine by oVirt.

the class BaseSystemModule method getGenericApiGWTService.

@Provides
@Singleton
public GenericApiGWTServiceAsync getGenericApiGWTService(final XsrfRpcRequestBuilder requestBuilder) {
    // no need to use GenericApiGWTServiceAsync.Util as this is GIN-managed singleton anyway
    GenericApiGWTServiceAsync service = GWT.create(GenericApiGWTService.class);
    // cast to ServiceDefTarget and set RPC request builder as needed
    ((ServiceDefTarget) service).setRpcRequestBuilder(requestBuilder);
    return service;
}
