Package org.codehaus.plexus.interpolation

Interface Summary

Interface	Description
BasicInterpolator	Knows how to do basic interpolation services.
FeedbackEnabledValueSource	Deprecated. Rolled into ValueSource now.
InterpolationPostProcessor	Used to allow full recursion of value interpolation before applying some rule to the result.
Interpolator	Interpolator interface.
QueryEnabledValueSource	Tracks the most recent expression processed by this value source implementation.
RecursionInterceptor	Logs expressions before resolution is attempted, and clears them after resolution is complete (or, fails all strategies).
ValueSource	Supplies one strategy for resolving a value for an interpolation expression.

Class Summary

Class	Description
AbstractDelegatingValueSource
AbstractFunctionValueSourceWrapper	ValueSource abstract implementation that wraps another value source.
AbstractValueSource
EnvarBasedValueSource	ValueSource which resolves expressions against the environment variables available from the underlying operating system (and possibly, the shell environment that created the present Java process).
FixedInterpolatorValueSource	A value source that allows a fixed interpolator to be injected into a regular interpolator.
InterpolatorFilterReader	A FilterReader implementation, that works with Interpolator interface instead of it's own interpolation implementation.
MapBasedValueSource	Wraps a Map, and looks up the whole expression as a single key, returning the value mapped to it.
ObjectBasedValueSource	Wraps an object, providing reflective access to the object graph of which the supplied object is the root.
PrefixAwareRecursionInterceptor	RecursionInterceptor implementation that provides support for expressions with multiple synonyms, such as project.build.directory == pom.build.directory == build.directory in Maven's POM.
PrefixedObjectValueSource	Wraps an arbitrary object with an ObjectBasedValueSource instance, then wraps that source with a PrefixedValueSourceWrapper instance, to which this class delegates all of its calls.
PrefixedPropertiesValueSource	Legacy support.
PrefixedValueSourceWrapper	ValueSource implementation which simply wraps another value source, and trims any of a set of possible expression prefixes before delegating the modified expression to be resolved by the real value source.
PropertiesBasedValueSource	ValueSource implementation that wraps a Properties instance, and does a simple lookup of the entire expression string as the parameter for Properties.getProperty(String), returning the result as the resolved value.
RegexBasedInterpolator	Expansion of the original RegexBasedInterpolator, found in plexus-utils, this interpolator provides options for setting custom prefix/suffix regex parts, and includes a RecursionInterceptor parameter in its interpolate(..) call, to allow the detection of cyclical expression references.
SimpleRecursionInterceptor	Simplest implementation of a RecursionInterceptor, which checks whether the existing interpolation effort is already attempting to resolve an exact expression, but has not finished.
SingleResponseValueSource	If the expression matches, simply return the response object.
StringSearchInterpolator

Exception Summary

Exception	Description
InterpolationCycleException
InterpolationException	Signals an unrecoverable error in the process of interpolating a string, such as the detection of an expression cycle.
