-<p>Provides support for defining and contributing variables for the purpose of
- string substitution.</p>
-
-<h2>Package Specification</h2>
-
-<p>This package provides classes and interfaces to support the definition and
- contribution of variables for the purpose of string substitution. The plug-in
- supports the recursive replacement of variables referenced by name in arbitrary
- strings with the value of the variable. Two types of variables are provided
- - value variables (<code>IValueVariable</code>) and dynamic variables (<code>IDynamicVariable</code>).
- A value variable has a simple setter and getter for its current value. A dynamic
- variable has an associated resolver that provides a variable's value each time
- it is referenced (replaced) in a string substitution. A dynamic variable may
- also provide an argument in its reference that can be used by its resolver to
- determine its substitution value.</p>
-<p>A variable manager (<code>IStringVariableManager</code>) is provided to manage
- the set of defined variables. Value variables may be created via API on the
- variable manager, or contributed via the <code>valueVariables</code> extension
- point. Dynamic variables must be contributed via the <code>dynamicVariables</code>
- extension point. The variable manager also provides change notification for
- value variables. The variable manager also provides an API for performing string
- substitution, which accepts a string, and returns a string with all variable
- references replaced by associated variable values.</p>
-<p>Variables are referenced in strings by enclosing them in braces, preceded with
- a dollar sign. For example, consider a variable defined with the name <code>foo</code>,
- and referenced in the following string: <code>&quot;abc${foo}ghi&quot;</code>.
- If the value of <code>foo</code> is <code>&quot;def&quot;</code>, the result
- of a string substitution would be <code>&quot;abcdefghi&quot;</code>. In the
- case of a dynamic variable, an (optional) argument is supplied by appending
- a colon and argument value after the variable name. For example <code>&quot;${foo:bar}&quot;</code>.
- In this case, the resolver associated with <code>foo</code> would be provided
- with the referenced argument (<code>bar</code>) when asked to resolve a value
- for the variable <code>foo</code>. </p>
