示例1: matchMethod
import com.sun.tools.javac.code.Types; //导入方法依赖的package包/类
@Override
public Description matchMethod(MethodTree tree, VisitorState state) {
ClassTree enclosingClazz = ASTHelpers.findEnclosingNode(state.getPath(), ClassTree.class);
if (tree.getModifiers().getFlags().contains(Modifier.DEFAULT)
&& IS_FUNCTIONAL_INTERFACE.matches(enclosingClazz, state)) {
Types types = Types.instance(state.context);
Set<Symbol> functionalSuperInterfaceSams =
enclosingClazz
.getImplementsClause()
.stream()
.filter(t -> IS_FUNCTIONAL_INTERFACE.matches(t, state))
.map(ASTHelpers::getSymbol)
.map(TypeSymbol.class::cast)
.map(types::findDescriptorSymbol) // TypeSymbol to single abstract method of the type
.collect(toImmutableSet());
// We designate an override of a superinterface SAM "behavior preserving" if it just
// calls the SAM of this interface.
Symbol thisInterfaceSam = types.findDescriptorSymbol(ASTHelpers.getSymbol(enclosingClazz));
// relatively crude: doesn't verify that the same args are passed in the same order
// so it can get false positives for behavior-preservingness (false negatives for the check)
TreeVisitor<Boolean, VisitorState> behaviorPreserving =
new BehaviorPreservingChecker(thisInterfaceSam);
if (!Collections.disjoint(
ASTHelpers.findSuperMethods(ASTHelpers.getSymbol(tree), types),
functionalSuperInterfaceSams)
&& !tree.accept(behaviorPreserving, state)) {
return describeMatch(tree);
}
}
return Description.NO_MATCH;
}
示例2: getFunctionalInterfaceMethod
import com.sun.tools.javac.code.Types; //导入方法依赖的package包/类
/**
* finds the corresponding functional interface method for a lambda expression
*
* @param tree the lambda expression
* @return the functional interface method
*/
