A use case that comes across frequently, is creating a String from a stream, where the stream-items are separated by a certain character. The Collectors.joining() method can be used for this, like in the following example: Stream<String> fruitStream = Stream.of("apple", "banana...

Your DocumentDB database can be created by using the CreateDatabaseAsync method of the DocumentClient class. A database is the logical container of JSON document storage partitioned across collections. using System.Net; using System.Threading.Tasks; using Microsoft.Azure.Documents; using Microso...

A document can be created by using the CreateDocumentAsync method of the DocumentClient class. Documents are user defined (arbitrary) JSON content. async Task CreateFamilyDocumentIfNotExists(DocumentClient client, string databaseName, string collectionName, Family family) { try { ...

DocumentDB supports rich queries against JSON documents stored in each collection. With a LINQ query IQueryable<Family> familyQuery = this.client.CreateDocumentQuery<Family>( UriFactory.CreateDocumentCollectionUri(databaseName, collectionName), queryOptions) .Where(f => f....

Deleting a database will remove the database and all children resources (collections, documents, etc.). await this.client.DeleteDatabaseAsync(UriFactory.CreateDatabaseUri(databaseName));

In some cases it may not suffice to know whether more that one methods were called. The calling order of methods is also important. In such case you may use InOrder class of Mockito to verify the order of methods. SomeClass mock1 = Mockito.mock(SomeClass.class); otherClass mock2 = Mockito.mock(Oth...

Set up some constants for the server and authentication information. Assuming LDAPv3, but it's easy enough to change that. // Authentication, and the name of the server. private const string LDAPUser = "cn=example:app:mygroup:accts,ou=Applications,dc=example,dc=com"; private readonly ch...

Assuming LDAPv3, but it's easy enough to change that. This is anonymous, unencrypted LDAPv3 LdapConnection creation. private const string TargetServer = "ldap.example.com"; Actually create the connection with three parts: an LdapDirectoryIdentifier (the server), and NetworkCredentials....

Any attempt to modify a const object results in undefined behavior. This applies to const variables, members of const objects, and class members declared const. (However, a mutable member of a const object is not const.) Such an attempt can be made through const_cast: const int x = 123; const_cas...

In Unix, files and directories beginning with a period usually contain settings for a specific program/a series of programs.
