java.lang.Objectcom.springsource.util.common.PropertyPlaceholderResolver
public final class PropertyPlaceholderResolver
Utility class for resolving placeholders inside a Properties
instance. These placeholders can refer to other
properties in the Properties
instance. The place holders may also have a modifier in them
${com.springsource:modifier}where everything after the colon is considered the modifier. This class does not interpret these modifiers but rather delegates to a
PropertyPlaceholderResolver.PlaceholderValueTransformer
for processing.
