Class FixedStringSearchInterpolator
- java.lang.Object
-
- org.codehaus.plexus.interpolation.fixed.FixedStringSearchInterpolator
-
- All Implemented Interfaces:
FixedValueSource
public class FixedStringSearchInterpolator extends Object implements FixedValueSource
A fixed string search interpolator is permanently bound to a given set of value sources, an is totally fixed and stateless over these value sources.
The fixed interpolator is also a #StatelessValueSource and can be used as a source for a different fixed interpolator, creating a scope chain.
Once constructed, this interpolator will always point to the same set of objects (value sources), in such a way that if the underlying object is fixed, expressions will always evaluate to the same result.
The fixed interpolator can be shared among different clients and is thread safe to the extent the underlying value sources can be accessed safely. Since interpolation expressions cannot modify the objects, thread safety concerns this will normally be limited to safe publication and memory model visibility of underlying objects.
The fixed interpolator can be a valuesource
