5.5.2 I18N.Encoder: stream operations

atEnd
Return whether the receiver can produce another character in the receiver; by default, this is true if there is another character in the origin.


atEndOfInput
Return whether there is another character in the origin. This method is for private use by encoders, calling it outside won't corrupt the internal state of the encoder but the result probably won't be meaningful (depending on the innards of the encoder).


next
Return the next character in the receiver; by default, this is the next character in the origin.


nextInput
Return the next character in the origin. This method is for private use by encoders, calling it outside may corrupt the internal state of the encoder.


nextInputAvailable: n into: aCollection startingAt: pos
Place up to N characters from the origin in aCollection. This method is for private use by encoders, calling it outside may corrupt the internal state of the encoder.


peekInput
Return the next character in the origin without advancing it.


species
We answer a string of Characters encoded in our destination encoding.
