This extension point provides a mechanism for defining dynamic variables used in string substitution. The value of a dynamic variable is resolved at the time a string substitution is performed, with an optional argument. a fully qualified identifier of the target extension point an optional identifier of the extension instance an optional name of the extension instance specifies a unique name for this variable. specifies a Java class which implements <code>org.eclipse.core.variables.IDynamicVariableResolver</code>, which is used to determine the value of the variable specifies a human-readable description of this variable Whether this variable supports an argument. When unspecified, the implied value is <code>true</code>. 3.0 The following is a definition of a dynamic variable that resolves to the name of the selected resource: <pre> <extension point="org.eclipse.core.variables.dynamicVariables"> <variable name="resource_name" expanderClass="com.example.ResourceNameExpander" description="The name of the selected resource"> </variable> </extension> </pre> Value of the attribute <b>resolver</b> must be a fully qualified name of a Java class that implements the interface <b>org.eclipse.core.variables.IDynamicVariableResolver</b>.
