Interface AttributeHolder

All Superinterfaces:

com.google.devtools.build.lib.skylarkinterface.SkylarkPrintable, com.google.devtools.build.lib.skylarkinterface.SkylarkValue

All Known Implementing Classes:

Attribute, BoolAttribute, DepAttribute, DepListAttribute, IntAttribute, IntListAttribute, OutputAttribute, OutputListAttribute, SourceAttribute, SourceListAttribute, SourceSortedSetAttribute, StringAttribute, StringListAttribute, StringSortedSetAttribute, UnconfiguredDepListAttribute, UnconfiguredOptionalDepAttribute

public interface AttributeHolder
extends com.google.devtools.build.lib.skylarkinterface.SkylarkValue

Simple wrapper object to hold onto Attribute objects and get around some type erasure problems in SkylarkDict.getContents(Class, Class, String). If using com.facebook.buck.core.starlark.rule.attr.Attribute<T>, then a Class<T> cannot be instantiated. If the generic Attribute type is passed and used, then it is a compile error. We need SkylarkDict.getContents(Class, Class, String) to succeed in order to validate the types of the objects in that dictionary, so add an intermediate class. This is terrible.
