pack-priv static void init() throws UnsatisfiedLinkError

Attempts to load the shared JNI library. First try loading the platform-specific library name (e.g. conscrypt_openjdk_jni-linux-x86_64). If that doesn't work, try to load the library via just the prefix (e.g. conscrypt_openjdk_jni). If not found, try the static library name. The non-suffixed dynamic library name is used by the Android build system, which builds the appropriate library for the system it's being run on under that name. The static library name is needed in order to support Java 8 static linking (http://openjdk.java.net/jeps/178), where the library name is used to invoke a library-specific load method (i.e. JNI_OnLoad_conscrypt).

Exceptions
UnsatisfiedLinkError:
if the library failed to load.

All Implemented Interfaces
java.util.Comparator
Sorts the errors in a list in descending order of value. After a list is sorted, the first element is the most important error.

compareback to summary
public int compare(NativeLibraryLoader.LoadResult o1, NativeLibraryLoader.LoadResult o2)

Implements java.util.Comparator.compare.

Doc from java.util.Comparator.compare.

Compares its two arguments for order. Returns a negative integer, zero, or a positive integer as the first argument is less than, equal to, or greater than the second.

The implementor must ensure that signum(compare(x, y)) == -signum(compare(y, x)) for all x and y. (This implies that compare(x, y) must throw an exception if and only if compare(y, x) throws an exception.)

The implementor must also ensure that the relation is transitive: ((compare(x, y)>0) && (compare(y, z)>0)) implies compare(x, z)>0.

Finally, the implementor must ensure that compare(x, y)==0 implies that signum(compare(x, z))==signum(compare(y, z)) for all z.

Parameters
o1:NativeLibraryLoader.LoadResult

the first object to be compared.

o2:NativeLibraryLoader.LoadResult

the second object to be compared.

Returns:int

a negative integer, zero, or a positive integer as the first argument is less than, equal to, or greater than the second.
