SnippetStub

public SnippetStub(String snippetMethodName,
                   HotSpotProviders providers,
                   HotSpotForeignCallLinkage linkage)

Creates a new snippet stub.

Parameters:

snippetMethodName - name of the single Snippet annotated method in the class of this object

linkage - linkage details for a call to the stub

SnippetStub

public SnippetStub(Class<? extends Snippets> snippetDeclaringClass,
                   String snippetMethodName,
