<title>IVariableSource</title>
<title>Example: The
<literal>VariablePlaceholderConfigurer</literal></title>
<para>The <literal>IVariableSource</literal> is the base interface for
providing the ability to get the value of property placeholders
(name-value) pairs from a variety of sources. Out of the box,
Spring.NET supports a number of variable sources that allow users to
obtain variable values from .NET config files, java-style property
files, environment variables, command line arguments and the registry
and the new connection strings configuration section in .NET 2.0. The
list of implementing classes is listed below. Please refer to the SDK
documentation for more information.</para>

<para>The <literal>VariablePlaceholderConfigurer</literal> is an
evolution of the <literal>PropertyPlaceHolderConfigurer</literal>. Out
of the box, Spring.NET supports a number of variable sources that
allow users to obtain variable values from .NET config files,
java-style property files, environment variables, command line
arguments and the registry and the new connection strings
configuration section in .NET 2.0. It is possible to add your own
variable sources to a <literal>VariablePlaceholderConfigurer</literal>
by implementing the <literal>IVariableSource</literal>
interface.</para>
