20 An object to which char sequences and values can be appended. The Appendable
21 interface must be implemented by any class whose instances are intended to
22 receive formatted output from a (|java.util.Formatter|) .
24 The characters to be appended should be valid Unicode characters as described
25 in Unicode Character Representation. Note that supplementary characters may be
26 composed of multiple 16-bit char values.
28 Appendables are not necessarily safe for multithreaded access. Thread safety is
29 the responsibility of classes that extend and implement this interface.
31 Since this interface may be implemented by existing classes with different
32 styles of error handling there is no guarantee that errors will be propagated
37 *java.lang.Appendable.append(char)*
39 public |java.lang.Appendable| append(char c)
40 throws |java.io.IOException|
42 Appends the specified character to this Appendable.
45 c - The character to append
47 Returns: A reference to this Appendable
49 *java.lang.Appendable.append(CharSequence)*
51 public |java.lang.Appendable| append(java.lang.CharSequence csq)
52 throws |java.io.IOException|
54 Appends the specified character sequence to this Appendable.
56 Depending on which class implements the character sequence csq, the entire
57 sequence may not be appended. For instance, if csq is a (|java.nio.CharBuffer|)
58 then the subsequence to append is defined by the buffer's position and limit.
61 csq - The character sequence to append. If csq is null, then the four characters
62 "null" are appended to this Appendable.
64 Returns: A reference to this Appendable
66 *java.lang.Appendable.append(CharSequence,int,int)*
68 public |java.lang.Appendable| append(
69 java.lang.CharSequence csq,
72 throws |java.io.IOException|
74 Appends a subsequence of the specified character sequence to this Appendable.
76 An invocation of this method of the form out.append(csq, start, end) when csq
77 is not null, behaves in exactly the same way as the invocation
81 out.append(csq.subSequence(start, end))
84 csq - The character sequence from which a subsequence will be appended. If csq is
85 null, then characters will be appended as if csq contained the four
87 start - The index of the first character in the subsequence
88 end - The index of the character following the last character in the subsequence
90 Returns: A reference to this Appendable
