Method Detail

decodeNativeMethodName

public static String[] decodeNativeMethodName(String str)

https://docs.oracle.com/javase/1.5.0/docs/guide/jni/spec/design.html Dynamic linkers resolve entries based on their names. A native method name is concatenated from the following components:

• the prefix Java_
• a mangled fully-qualified class name
• an underscore (“_”) separator
• a mangled method name
• for overloaded native methods, two underscores (“__”) followed by the mangled argument signature

Escape Sequence Denotes _0XXXX a Unicode character XXXX. Note that lower case is used to represent non-ASCII Unicode characters, e.g., _0abcd as opposed to _0ABCD. _1 the character “_” _2 the character “;” in signatures _3 the character “[“ in signatures

Returns:
