Description</H2><P>Provides the naming service for Java IDL. <P> The package and all its classes and interfaces were generated by running the tool <code>idltojava</code> on the file <code>nameservice.idl</code>, which is a module written in OMG IDL. <P> <H2>Interfaces</H2> The package <tt>org.omg.CosNaming</tt> contains two public interfaces and several auxiliary classes. <P> The interfaces are: <UL> <LI><TT>NamingContext</TT> <LI><TT>BindingIterator</TT> </UL> <P> These two interfaces provide the means to bind/unbind names and object references, to retrieve bound object references, and to iterate through a list of bindings. The <code>NamingContext</code> interface supplies the main functionality for the naming service, and <code>BindingIterator</code> provides a means of iterating through a list of name/object reference bindings. <P> <H2>Auxiliary Classes</H2> In order to map an OMG IDL interface to the Java programming language, the idltojava compiler creates Java classes that can be thought of as auxiliary classes. Comments for the generated auxiliary classes used by the interfaces <code>NamingContext</code> and <code>BindingIterator</code> are included here. <P> <H3>Classes Used by <code>NamingContext</code> and <code>BindingIterator</code></H3> The following are classes used by the naming service. (Helper and holder classes, which are generated for each of the classes listed here, are discussed below.) <UL> <LI><code>public final class <B>NameComponent</B></code> -- a building block for names. (Names are bound to object references in a naming context.) <P>A name is an array of one or more <code>NameComponent</code> objects. A name with a single <code>NameComponent</code> is called a <I>simple name</I>; a name with multiple <code>NameComponent</code> objects is called a <I>compound name</I>. <P> A <code><B>NameComponent</B></code> object consists of two fields: <OL> <LI><code><B>id</B></code> -- a <code>String</code> used as an identifier <LI><code><B>kind</B></code> -- a <code>String</code> that can be used for any descriptive purpose. Its importance is that it can be used to describe an object without affecting syntax. The C programming language, for example, uses the the syntactic convention of appending the extension ".c" to a file name to indicate that it is a source code file. In a <code>NameComponent</code> object, the <code>kind</code> field can be used to describe the type of object rather than a file extension or some other syntactic convention. Examples of the value of the <code>kind</code> field include the strings <code>"c_source"</code>, <code>"object_code"</code>, <code>"executable"</code>, <code>"postscript"</code>, and <code>""</code>. It is not unusual for the <code>kind</code> field to be the empty string. </OL> <P> In a name, each <code>NameComponent</code> object except the last denotes a <code>NamingContext</code> object; the last <code>NameComponent</code> object denotes the bound object reference. This is similar to a path name, in which the last name is the file name, and all names before it are directory names.<p> <P> <LI><code>public final class <B>Binding</B></code> -- an object that associates a name with an object reference or a naming context. A <code>Binding</code> object has two fields: <OL> <LI><code><B>binding_name</B></code> - an array of one or more <code>NameComponent</code> objects that represents the bound name <LI><code><B>binding_type</B></code> - a <code>BindingType</code> object indicating whether the binding is between a name and an object⌨️ 快捷键说明
