Class CodeInfoTable

java.lang.Object

com.oracle.svm.core.code.CodeInfoTable

public class CodeInfoTable
extends Object

Provides the main entry points to look up metadata for code, either ahead-of-time compiled code in the native image or code compiled at runtime.

Users of this class must take special care because code can be invalidated at arbitrary times and their metadata can be freed, see notes on CodeInfoAccess.
