#Class SkStream

SkStream describes an abstract class that provides readable serial access to 
data. Subclass SkFILEStream stores readable data in a file. Subclass 
SkMemoryStream stores readable data in memory.

SkStream data is immutable; data access is synchronous. Reading Stream data
returns only as many bytes as were available when Stream was created. Unlike
traditional streams, additional data will not become available at a later time
or on a subsequent read request.

# ------------------------------------------------------------------------------

#Method virtual size_t read(void* buffer, size_t size) = 0
#In incomplete
#Line # incomplete ##

Reads or skips size number of bytes.
If buffer is nullptr, skip size bytes, return how many were skipped.
If buffer is not nullptr, copy size bytes into buffer, return how many were copied.

#Param buffer  when nullptr skip size bytes, otherwise copy size bytes into buffer
##
#Param size  the number of bytes to skip or copy
##

#Return  the number of bytes actually read.

#Method ##

# ------------------------------------------------------------------------------

#Method size_t skip(size_t size)
#In incomplete
#Line # incomplete ##

Skip size number of bytes. #Param size  incomplete ##

#Return  the actual number bytes that could be skipped
##

#Example

#Method ##

# ------------------------------------------------------------------------------

#Method virtual size_t peek(void* buffer, size_t size) const
#In incomplete
#Line # incomplete ##

Attempt to peek at size bytes.
If this stream supports peeking, copy min(size, peekable bytes) into
buffer, and return the number of bytes copied.
If the stream does not support peeking, or cannot peek any bytes,
return 0 and leave buffer unchanged.
The stream is guaranteed to be in the same visible state after this
call, regardless of success or failure.

#Param buffer  must not be nullptr, and must be at least size bytes. Destination
        to copy bytes
##
#Param size  number of bytes to copy
##

#Return  number of bytes peeked/copied.
##

#Example
// incomplete

#Method ##

# ------------------------------------------------------------------------------

#Method virtual bool isAtEnd() const = 0
#In incomplete
#Line # incomplete ##

Returns true when all the bytes in the stream have been read.
This may return true early (when there are no more bytes to be read)
or late (after the first unsuccessful read).

#Return incomplete ##
