ClassResolver (archunit 0.12.0 API)

All Known Implementing Classes:

ClassResolverFromClasspath, SelectedClassResolverFromClasspath
```
@PublicAPI(usage=INHERITANCE)
public interface ClassResolver
```
The ClassFileImporter will use the configured ClassResolver, to determine how to resolve further dependencies.

For example, if you import the package com.foo.bar, and some class com.foo.bar.FooBar calls a method of com.other.Dependency, the ClassResolver will decide how this dependency should be treated, i.e. should the class tried to be located somehow, e.g. on the classpath, or should instead a stub with the respective type name be created.

Before any call of tryResolve(String), ArchUnit will always call setClassUriImporter(ClassUriImporter) and supply a respective ClassUriImporter. Thus the job of ClassResolver is just, to resolve the correct URI, where to locate the class. The ClassUriImporter can then import any given URI as a JavaClass.

Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`void`	`setClassUriImporter(ClassResolver.ClassUriImporter classUriImporter)`	Always called BEFORE `tryResolve(String)`.
`Optional<JavaClass>`	`tryResolve(java.lang.String typeName)`	ArchUnit will call this method, to resolve any missing `JavaClasses`, needed to build the class graph (i.e.

- Method Detail
  - setClassUriImporter
```
void setClassUriImporter(ClassResolver.ClassUriImporter classUriImporter)
```
    Always called BEFORE tryResolve(String).
    
    Parameters:
    
    classUriImporter - to import a JavaClass from any supplied URI
  - tryResolve
```
Optional<JavaClass> tryResolve(java.lang.String typeName)
```
    ArchUnit will call this method, to resolve any missing JavaClasses, needed to build the class graph (i.e. targets of method calls, field accesses, super classes, interfaces, ...)
    
    Parameters:
    
    typeName - The type name to resolve as JavaClass
    
    Returns:
    
    Optional.of(resolvedClass), if the JavaClass could be successfully imported, otherwise Optional.absent()
