Metadata describing the structure of a (at least partially) encrypted
A buffer's data is considered to be partitioned into "subSamples",
each subSample starts with a (potentially empty) run of plain,
unencrypted bytes followed by a (also potentially empty) run of
encrypted bytes. If pattern encryption applies, each of the latter runs
is encrypted only partly, according to a repeating pattern of "encrypt"
and "skip" blocks. numBytesOfClearData can be null to indicate that all
data is encrypted. This information encapsulates per-sample metadata as
outlined in ISO/IEC FDIS 23001-7:2011 "Common encryption in ISO base
media file format files".
Causes the current thread to wait until another thread invokes the
notify() method or the
notifyAll() method for this object, or
some other thread interrupts the current thread, or a certain
amount of real time has elapsed.
Returns a string representation of the object. In general, the
toString method returns a string that
"textually represents" this object. The result should
be a concise but informative representation that is easy for a
person to read.
It is recommended that all subclasses override this method.
The toString method for class Object
returns a string consisting of the name of the class of which the
object is an instance, the at-sign character `@', and
the unsigned hexadecimal representation of the hash code of the
object. In other words, this method returns a string equal to the
