Class MultiPlatformTargetConfigurationTransformer

java.lang.Object

com.facebook.buck.core.model.impl.MultiPlatformTargetConfigurationTransformer

All Implemented Interfaces:

TargetConfigurationTransformer

public class MultiPlatformTargetConfigurationTransformer
extends Object
implements TargetConfigurationTransformer

TargetConfigurationTransformer that transforms a single target configuration with a multiplatform as a target platform to multiple target configurations each containing platforms that are forming multiplatform.

For example, a multiplatform "A" contains "B" as a base platform and "X", "Y", "Z" as nested platforms. In this case a target configuration with the "A" platform will be transformed to a set of platforms: "A", "X", "Y", "Z". Note that this transformation doesn't use "B" since the multiplatform uses its base platform to match constraints. Using the multiplatform instead of the base platform allows us to keep the rest of attributes (that don't use transformations) consistent with attributes that use transformations.
