DependencySelector

All Known Implementing Classes:

AndDependencySelector, ExclusionDependencySelector, OptionalDependencySelector, ScopeDependencySelector, StaticDependencySelector
```
public interface DependencySelector
```
Decides what dependencies to include in the dependency graph.
Note: Implementations must be stateless.
Warning: This hook is called from a hot spot and therefore implementations should pay attention to performance. Among others, implementations should provide a semantic equals() method.

Modifier and Type	Method	Description

- Method Detail
  - selectDependency
```
boolean selectDependency(Dependency dependency)
```
    Decides whether the specified dependency should be included in the dependency graph.
    
    Parameters:
    
    dependency - The dependency to check, must not be null.
    
    Returns:
    
    false if the dependency should be excluded from the children of the current node, true otherwise.
  - deriveChildSelector
```
DependencySelector deriveChildSelector(DependencyCollectionContext context)
```
    Derives a dependency selector for the specified collection context. When calculating the child selector, implementors are strongly advised to simply return the current instance if nothing changed to help save memory.
    
    Parameters:
    
    context - The dependency collection context, must not be null.
    
    Returns:
    
    The dependency selector for the target node or null if dependencies should be unconditionally included in the sub graph.
