Method Detail

resetVersion

public static void resetVersion()

Resets _tigerEnabled based upon the version of the runtime environment that is being used.

isTigerEnabled

public static boolean isTigerEnabled()

Accessor method for _tigerEnabled. Returns true if the features in 1.5 are enabled currently.

Returns:

boolean - true if 1.5 features are enabled

setTigerEnabled

public static void setTigerEnabled(boolean enabled)

Allows the features in 1.5 to be enabled or disabled. Used only in test cases.

Parameters:

enabled - - a boolean that specifies whether or not Tiger features are to be enabled

assertTigerEnabled

public static void assertTigerEnabled(String msg)

To be called before a feature of 1.5 is used. Asserts that Tiger features are enabled.

Parameters:

msg - The error message if 1.5 is not enabled

isVarArgs

public static boolean isVarArgs(Method m)

Returns:

@{code true} iff m has the vararg modifier set.

isVarArgs

public static boolean isVarArgs(Constructor<?> c)

Returns:

@{code true} iff c has the vararg modifier set.

isBridge

public static boolean isBridge(Method m)

Returns:

@{code true} iff m has the bridge modifier set.

isEnum

public static boolean isEnum(Class<?> c)

Returns:

@{code true} iff c has the enum modifier set.

isEnumConstant

public static boolean isEnumConstant(Field f)

Returns:

@{code true} iff f has the enum modifier set.

correspondingBoxingType

public static Class<?> correspondingBoxingType(Class<?> primType)

Returns the reference type that corresponds to the given primitive type. If the type given is not primitive, it returns the given type.

Parameters:

primType - the primitive type

Returns:

the corresponding reference type

correspondingPrimType

public static Class<?> correspondingPrimType(Class<?> refType)

Returns the primitive type that corresponds to the given reference type. If the given type is not a boxing type, it returns the given type.

Parameters:

refType - the reference type

Returns:

the corresponding primitive type

isBoxingType

public static boolean isBoxingType(Class<?> c)

Returns if the given class is a reference type

Parameters:

c - the class that may be a reference type

Returns:

boolean that is true if the input class is a boxing type

isIntegralType

public static boolean isIntegralType(Class<?> c)

Returns true iff the given class is an integral type This includes both primitive and boxing integral types.

Allowed primitives: byte, char, short, int, long Allowed Refrence: Byte, Character, Short, Integer, Long

Parameters:

c - The class to check

Returns:

true iff the given class is an integral type

boxesTo

public static boolean boxesTo(Class<?> prim,
                              Class<?> ref)

Returns true iff the given primitive class can be boxed to the given reference class.

Parameters:

prim - - the primitive class being boxed

ref - - the reference class being boxed to

Returns:

true iff the given primitive class can be boxed to the given reference class
