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

Returns:

This jar file's location or null if this jar file's location is inaccessible.

Throws:

java.io.IOException - If an I/O exception occurs.

createJarFile

private static java.io.File createJarFile()

Returns:

The provided agent.

Throws:

java.io.IOException - If the agent cannot be written to disk.
