public abstract class DependencyModifier
extends java.lang.Object
```
A DependencyModifier defines how to modify a dependency inside a custom dependencies block to select a different variant.
Since:

8.0

API Note:
Gradle has specific extensions to make explicit calls to modify(...) unnecessary from the DSL.
- For Groovy DSL, we create call(...) equivalents for all the modify(...) methods.
- For Kotlin DSL, we create invoke(...) equivalents for all the modify(...) methods.
Implementation Requirements:

The only method that should be implemented is modifyImplementation(ModuleDependency). Other abstract methods are used to inject necessary services and should not be implemented.

Implementation Note:

All implementations of modify(...) delegate to modifyImplementation(ModuleDependency).
Changes to this interface may require changes to the extension module for Groovy DSL or extension functions for Kotlin DSL.

All Methods Instance Methods Abstract Methods Concrete Methods
Modifier and Type	Method	Description
`protected abstract DependencyFactory`	`getDependencyFactory()`	A dependency factory is used to convert supported dependency notations into `Dependency` instances.
`<D extends ModuleDependency> D`	`modify(D dependency)`	Takes a given `ModuleDependency` and modifies the dependency to select the variant of the given module.
`ExternalModuleDependency`	`modify(java.lang.CharSequence dependencyNotation)`	Create an `ExternalModuleDependency` from the given notation and modifies it to select the variant of the given module as described in `modify(ModuleDependency)`.
`<D extends ModuleDependency> Provider<D>`	`modify(Provider<D> providerToDependency)`	Takes a given `Provider` to a `ExternalModuleDependency` and modifies the dependency to select the variant of the given module as described in `modify(ModuleDependency)`.
`Provider<? extends MinimalExternalModuleDependency>`	`modify(ProviderConvertible<? extends MinimalExternalModuleDependency> providerConvertibleToDependency)`	Takes a given `Provider` to a `MinimalExternalModuleDependency` and modifies the dependency to select the variant of the given module as described in `modify(ModuleDependency)`.
`protected abstract void`	`modifyImplementation(ModuleDependency dependency)`	Modify the given dependency.

```
@Inject
protected abstract DependencyFactory getDependencyFactory()
```
    A dependency factory is used to convert supported dependency notations into Dependency instances.
    
    Returns:
    
    a dependency factory
    
    See Also:
    
    DependencyFactory
    
    Implementation Requirements:
    
    Do not implement this method. Gradle generates the implementation automatically.
  - modify
```
public final ExternalModuleDependency modify(java.lang.CharSequence dependencyNotation)
```
    Create an ExternalModuleDependency from the given notation and modifies it to select the variant of the given module as described in modify(ModuleDependency).
    
    Parameters:
    
    dependencyNotation - the dependency notation
    
    Returns:
    
    the modified dependency
    
    See Also:
    
    DependencyFactory.create(CharSequence)
  - modify
```
public final Provider<? extends MinimalExternalModuleDependency> modify(ProviderConvertible<? extends MinimalExternalModuleDependency> providerConvertibleToDependency)
```
    Takes a given Provider to a MinimalExternalModuleDependency and modifies the dependency to select the variant of the given module as described in modify(ModuleDependency).
    
    Parameters:
    
    providerConvertibleToDependency - the provider
    
    Returns:
    
    a provider to the modified dependency
  - modify
```
public final <D extends ModuleDependency> Provider<D> modify(Provider<D> providerToDependency)
```
    Takes a given Provider to a ExternalModuleDependency and modifies the dependency to select the variant of the given module as described in modify(ModuleDependency).
    
    Parameters:
    
    providerToDependency - the provider
    
    Returns:
    
    a provider to the modified dependency
  - modify
```
public final <D extends ModuleDependency> D modify(D dependency)
```
    Takes a given ModuleDependency and modifies the dependency to select the variant of the given module. Dependency resolution may fail if the given module does not have a compatible variant.
    The dependency will be copied, so the original dependency will not be modified.
    
    Type Parameters:
    
    D - the type of the ModuleDependency
    
    Parameters:
    
    dependency - the dependency to modify
    
    Returns:
    
    the modified dependency
  - modifyImplementation
```
protected abstract void modifyImplementation(ModuleDependency dependency)
```
    Modify the given dependency.
    
    Parameters:
    
    dependency - the dependency to modify
    
    Since:
    
    8.4
    
    Implementation Requirements:
    
    This method must be implemented.
