Summary

Public methods
`abstract @NonNull T`	`<T extends Object> buildTypeExtension(@NonNull Class<@NonNull T> extensionType)` Returns the `variant` specific extension registered through the com.android.build.api.extension.DslExtension.buildTypeExtensionType API.
`abstract @NonNull VariantT`	`getVariant()` Gets the variant object the `com.android.build.api.variant.VariantExtension` should be associated with.
`abstract @NonNull List<@NonNull T>`	`<T extends Object> productFlavorsExtensions( @NonNull Class<@NonNull T> extensionType )` Returns the `variant` specific extension registered through the com.android.build.api.extension.DslExtension.productFlavorExtensionType API.
`abstract @NonNull T`	`<T extends Object> projectExtension(@NonNull Class<@NonNull T> extensionType)` Returns the project (across variants) extension registered through the com.android.build.api.extension.DslExtension.projectExtensionType API.

abstract @NonNull T <T extends Object> buildTypeExtension(@NonNull Class<@NonNull T> extensionType)

Returns the variant specific extension registered through the com.android.build.api.extension.DslExtension.buildTypeExtensionType API.

Returns
`@NonNull T`	the custom extension for the `variant`'s build type.

abstract @NonNull VariantT getVariant()

Gets the variant object the com.android.build.api.variant.VariantExtension should be associated with.

abstract @NonNull List<@NonNull T> <T extends Object> productFlavorsExtensions(
    @NonNull Class<@NonNull T> extensionType
)

Returns the variant specific extension registered through the com.android.build.api.extension.DslExtension.productFlavorExtensionType API.

Returns
`@NonNull List<@NonNull T>`	a `List` of `T` extension for all the defined product flavors in the project. The order of the elements is the same as the order of product flavors returned by the `Variant.productFlavors`

abstract @NonNull T <T extends Object> projectExtension(@NonNull Class<@NonNull T> extensionType)

Returns the project (across variants) extension registered through the com.android.build.api.extension.DslExtension.projectExtensionType API.
