java.lang.Appendable |
Known Indirect Subclasses |
Declares methods to append characters or character sequences. Any class that
implements this interface can receive data formatted by a
Formatter
. The appended character or character sequence
should be valid according to the rules described in
Unicode Character Representation
.
Appendable
itself does not guarantee thread safety. This
responsibility is up to the implementing class.
Implementing classes can choose different exception handling mechanism. They
can choose to throw exceptions other than IOException
or they do not
throw any exceptions at all and use error codes instead.
Public Methods | |||||||||||
---|---|---|---|---|---|---|---|---|---|---|---|
Appends the character sequence
csq . | |||||||||||
Appends a subsequence of
csq . | |||||||||||
Appends the specified character.
|
Appends the character sequence csq
. Implementation classes may
not append the whole sequence, for example if the target is a buffer with
limited size.
If csq
is null
, the characters "null" are appended.
csq | the character sequence to append. |
---|
Appendable
.IOException | if an I/O error occurs. |
---|
Appends a subsequence of csq
.
If csq
is not null
then calling this method is equivalent
to calling append(csq.subSequence(start, end))
.
If csq
is null
, the characters "null" are appended.
csq | the character sequence to append. |
---|---|
start | the first index of the subsequence of csq that is
appended. |
end | the last index of the subsequence of csq that is
appended. |
Appendable
.IndexOutOfBoundsException | if start < 0 , end < 0 , start > end
or end is greater than the length of csq . |
---|---|
IOException | if an I/O error occurs. |
Appends the specified character.
c | the character to append. |
---|
Appendable
.IOException | if an I/O error occurs. |
