Method Detail

values

public static Tools[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (Tools c : Tools.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static Tools valueOf(java.lang.String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

java.lang.IllegalArgumentException - if this enum type has no constant with the specified name

java.lang.NullPointerException - if the argument is null

getCurrentPID

public static java.lang.String getCurrentPID()

Gets the current JVM PID.

Returns:

Returns the PID.

getBytesFromStream

public static byte[] getBytesFromStream(java.io.InputStream stream)
                                 throws java.io.IOException

Gets class bytes from a stream.

Parameters:

stream - The stream to get class bytes from.

Returns:

Returns a byte[] representation of given class.

Throws:

java.io.IOException - When an IO error occurs preventing us from retrieving class bytes.

getBytesFromClass

public static byte[] getBytesFromClass(java.lang.Class<?> clazz)
                                throws java.io.IOException

Gets bytes from a class.

Parameters:

clazz - The class to retrieve bytes from.

Returns:

Returns a byte[] representation of given class.

Throws:

java.io.IOException - When an IO error occurs preventing us from retrieving class bytes.

getBytesFromResource

public static byte[] getBytesFromResource(java.lang.ClassLoader clazzLoader,
                                          java.lang.String resource)
                                   throws java.io.IOException

Gets bytes from a resource.

Parameters:

resource - The resource string.

Returns:

Returns a byte[] representation of given resource.

Throws:

java.io.IOException - When an IO error occurs preventing us from retrieving class bytes.

addToLibPath

public static void addToLibPath(java.lang.String path)
                         throws java.lang.NoSuchFieldException,
                                java.lang.SecurityException,
                                java.lang.IllegalArgumentException,
                                java.lang.IllegalAccessException

Adds a a path to the current java.library.path.

Parameters:

path - The path to the library.

Throws:

java.lang.SecurityException - When we couldn't add a path due to the JVM security restrictions.

java.lang.NoSuchFieldException - When we couldn't find the sys_paths field in the loaded library.

java.lang.IllegalAccessException - When we could not access the actual sys_paths field in the loaded library.

java.lang.IllegalArgumentException - When we're dumbasses and can't remember what field we wanted.
