Annotation Types Summary

Annotation Type	Description
BaselineNoRegisters	Some methods shouldn't use registers for locals and stack values.
BaselineSaveLSRegisters	Methods with this pragma that are BaselineCompiled should save in its prologue, ALL registers that can be used to store local and stack registers in any BaselineCompiled method.
DynamicBridge	Methods of a class that implements this interface are treated specially by the compilers.
Entrypoint	The entrypoint annotation indicates that the method or field is directly accessed by the compiler.
Inline	This pragma indicates that a particular method should always be inlined by the optimizing compiler.
Interruptible	By default all Java code is interruptible, that is scheduling or garbage collection may occur at points within the code.
LogicallyUninterruptible	Deprecated
NativeBridge	Methods of a class that implements this interface are treated specially by the compilers: They are only called from C or C++ program The compiler will generate the necessary prolog to insert a glue stack frame to map from the native stack/register convention to RVM's convention It is an error to call these methods from Java
NoBoundsCheck	This pragma indicates that a particular method should never have bounds checks generated.
NoCheckStore	Methods with this annotation do not perform a checkstore on stores into object arrays.
NoEscapes	Use this annotation to mark methods that won't cause their reference arguments to escape.
NoInline	This pragma indicates that a particular method should never be inlined by the optimizing compiler.
NonMoving	Use this annotation to mark types that must never move.
NonMovingAllocation	Use this annotation to mark methods for which all allocation must never move.
NoNullCheck	This pragma indicates that a particular method should never have null checks generated.
NoOptCompile	This pragma indicates that a particular method should never be compiled by the optimizing compiler.
Preemptible	By default all Java code is interruptible, that is scheduling or garbage collection may occur at points within the code.
Pure	This pragma is used to indicate a method has no side effects.
RawStorage	When applied to class this annotation indicates that the data component of this field consists of an intrinsically managed chunk of raw memory of the specified size.
ReferenceFieldsVary	This annotation marks types which have fields that can be marked as either traced or untraced by the VM.
RuntimeFinal	This pragma is used to indicate a field will be final in the running VM.
RuntimePure	This pragma is a variant of Pure that is used to mark methods that have a special behaviour at boot image writing time and are Pure at runtime
SaveVolatile	Methods of a class that implements this interface are treated specially by the machine code compiler: the method prologue saves all the volatile registers and the method epilogue restores all the volatile registers
SpecializedMethodInvoke	This pragma indicates that a particular method is a specialized method invocation point, and could be optimized as such.
SysCallNative	An annotation for static native methods to show that they should be compiled as system calls.
Uninterruptible	By default all Java code is interruptible, that is scheduling or garbage collection may occur at points within the code.
UninterruptibleNoWarn	A pragma that has the same direct effect as Uninterruptible but also suppresses checking of uninterruptibility violations for the method.
Unpreemptible	By default all Java code is interruptible, that is scheduling or garbage collection may occur at points within the code.
UnpreemptibleNoWarn	A special case of Unpreemptible where the code may call out to other interruptible routines.
Untraced	Use this annotation to mark fields that are read without the knowledge of the memory management system.
