public class PragmaException
extends RuntimeException

The root of the pragma exception hierarchy. These exceptions are all dummy exceptions that are never actually thrown. Methods declare them to be thrown as a way of indicating various properties.

Field Summary

static int	ALLOW_INLINED Bit flag for methods that have relaxed inlinning by the translator.
static int	FORCE_INLINED
static int	FORCE_INLINED_A Bit flag for methods that are forceably inlined by the translator.
static int	HOSTED Bit flag for hosted methods.
static int	INTERPRETER_INVOKED Bit flag for methods that should only be invoked from the interpreter.
static int	NATIVE Bit flag for methods that are made into native methods by the translator.
static int	NOT_INLINED Bit flag for methods that are never inlined by the translator.
static int	REPLACEMENT_CONSTRUCTOR Bit flag for replacement constructors.

Constructor Summary

PragmaException()

Method Summary

static boolean	isAllowInlined(int pragmaFlags) Given a bit mask, tells whether the method must be inlined by the translator.
static boolean	isForceInlined(int pragmaFlags) Given a bit mask, tells whether the method must be inlined by the translator.
static boolean	isHosted(int pragmaFlags) Given a bit mask, tells whether the method is run only in a hosted environment.
static boolean	isInterpreterInvoked(int pragmaFlags) Given a bit mask, tells whether the method is to be invoked only from the interpreter or JIT compiled code.
static boolean	isNative(int pragmaFlags) Given a bit mask, tells whether the method will be turned into a native method by the translator.
static boolean	isNotInlined(int pragmaFlags) Given a bit mask, tells whether the method is never inlined by the translator.
static boolean	isReplacementConstructor(int pragmaFlags) Given a bit mask, tells whether a method has its body replace a constructor with the same signature.
static int	toModifier(String className) Converts the name of a pragma class to a corresponding bit constant.

Method Detail

isHosted

public static boolean isHosted(int pragmaFlags)

Given a bit mask, tells whether the method is run only in a hosted environment.

isReplacementConstructor

public static boolean isReplacementConstructor(int pragmaFlags)

Given a bit mask, tells whether a method has its body replace a constructor with the same signature. Such methods should never be explicitly called.

isInterpreterInvoked

public static boolean isInterpreterInvoked(int pragmaFlags)

Given a bit mask, tells whether the method is to be invoked only from the interpreter or JIT compiled code.

isNative

public static boolean isNative(int pragmaFlags)

Given a bit mask, tells whether the method will be turned into a native method by the translator.

isForceInlined

public static boolean isForceInlined(int pragmaFlags)

Given a bit mask, tells whether the method must be inlined by the translator.

isAllowInlined

public static boolean isAllowInlined(int pragmaFlags)

Given a bit mask, tells whether the method must be inlined by the translator.

isNotInlined

public static boolean isNotInlined(int pragmaFlags)

Given a bit mask, tells whether the method is never inlined by the translator.

toModifier

public static int toModifier(String className)

Converts the name of a pragma class to a corresponding bit constant.

Parameters:

className - the name of one of the hard-wired pragma exception classes

Returns:

the constant corresponding to className or 0 if className does not denote a pragma
