Method Detail

registerObjectFields

public abstract void registerObjectFields(CodeInfo codeInfo)

Notify the GC that a code metadata object references Java heap objects from native-memory.

registerCodeConstants

public abstract void registerCodeConstants(CodeInfo codeInfo)

Notify the GC that run-time compiled code has embedded references to Java heap objects.

registerFrameMetadata

public abstract void registerFrameMetadata(CodeInfo codeInfo)

Notify the GC about frame metadata for run-time compiled code that references Java heap objects from native-memory.

registerDeoptMetadata

public abstract void registerDeoptMetadata(CodeInfo codeInfo)

Notify the GC about deoptimization metadata for run-time compiled code that references Java heap objects from native-memory.

unregisterCodeConstants

public abstract void unregisterCodeConstants(CodeInfo codeInfo)

Notify the GC that the application is going to invalidate run-time compiled code that has embedded references to Java heap objects. This notification must not be triggered if the GC itself frees a code metadata object.
