Interface SelectorListResolver

All Known Implementing Classes:

AbstractSelectorListResolver, DefaultSelectorListResolver, ThrowingSelectorListResolver, UnconfiguredSelectorListResolver

public interface SelectorListResolver

A resolver that analyzes SelectorList, evaluates selectable statements and constructs the final value that is produced by concatenating selected values (the type of the elements determines the process of concatenation.)

Method Summary

Modifier and Type	Method and Description
<T> T	resolveList(SelectableConfigurationContext configurationContext, BuildTarget buildTarget, String attributeName, SelectorList<T> selectorList, Concatable<T> concatable, DependencyStack dependencyStack) Resolves the elements in a given SelectorList and returns the concatenated value.

Method Detail

resolveList

@Nullable
<T> T resolveList(SelectableConfigurationContext configurationContext,
                            BuildTarget buildTarget,
                            String attributeName,
                            SelectorList<T> selectorList,
                            Concatable<T> concatable,
                            DependencyStack dependencyStack)

Resolves the elements in a given SelectorList and returns the concatenated value.

Type Parameters:

T - the type of elements stored in the provided selectable list

Parameters:

buildTarget - the build target that contains the given list in its arguments

attributeName - the name of the attribute that holds the given selector list

selectorList - a list with selectable elements

concatable - to be used when concatenating select items (e. g. lists or strings)

dependencyStack - used to provide error stacks

Returns:

an object produced by concatenating resolved elements of the given list or null if the list is resolved to an absent element
