Method Detail

uncheckedCast

public static <T> T uncheckedCast(Class<T> type,
                                  Object object)

Statically cast an object to an arbitrary Object type. Dynamically checked.

uncheckedCast

public static <T> T uncheckedCast(Object object)

Statically cast an object to an arbitrary Object type. Dynamically checked.

atPutGrow

public static <T> void atPutGrow(List<T> list,
                                 int pos,
                                 T x,
                                 T filler)

Sets the element at a given position of a list and ensures that this position exists. If the list is current shorter than the position, intermediate positions are filled with a given value.

Parameters:

list - the list to put the element into

pos - the position at which to insert the element

x - the element that should be inserted

filler - the filler element that is used for the intermediate positions in case the list is shorter than pos

indent

public static String indent(String lines,
                            String indentation)

Prepends the String indentation to every line in String lines, including a possibly non-empty line following the final newline.

zero

public static JavaConstant zero(JavaKind kind)

Returns the zero value for a given numeric kind.

one

public static JavaConstant one(JavaKind kind)

Returns the one value for a given numeric kind.

printInlining

public static void printInlining(ResolvedJavaMethod method,
                                 int bci,
                                 int inliningDepth,
                                 boolean success,
                                 String msg,
                                 Object... args)

Print a HotSpot-style inlining message to the console.

setAccessible

public static void setAccessible(Field field,
                                 boolean flag)

Calls AccessibleObject.setAccessible(boolean) on field with the value flag.

setAccessible

public static void setAccessible(Executable executable,
                                 boolean flag)

Calls AccessibleObject.setAccessible(boolean) on executable with the value flag.

hexStringToBytes

public static byte[] hexStringToBytes(String hex)

Converts a hex string to a byte array. Two characters are converted to a byte at a time.

Parameters:

hex - the hex string

Returns:

byte array
