For example, consider an address book entry that represents a single person along with zero or more phone numbers and zero or more addresses. This could be modeled in an object-oriented implementation by a "Person object " with an attribute/field to hold each data item that the entry comprises: the person's name, a list of phone numbers, and a ...
In this Java example, the Printer class has a print method. This print method, rather than performing the print itself, forwards to an object of class RealPrinter. To the outside world it appears that the Printer object is doing the print, but the RealPrinter object is the one actually doing the work.
For function that manipulate strings, modern object-oriented languages, like C# and Java have immutable strings and return a copy (in newly allocated dynamic memory), while others, like C manipulate the original string unless the programmer copies data to a new string.
The interface of an object conforming to this pattern would include functions such as Create, Read, Update, and Delete, that operate on objects that represent domain entity types in a data store. A Data Mapper is a Data Access Layer that performs bidirectional transfer of data between a persistent data store (often a relational database ) and ...

In JNI, for example, C code which "holds on to" object references that it receives from Java must communicate this information successfully to the Java virtual machine or Java Runtime Environment (JRE), otherwise, Java may delete objects before C finishes with them. (The C code must also explicitly release its link to any such object once C has ...
