| java.lang.Appendable
All known Subclasses: java.lang.AbstractStringBuilder,
| Appendable | | public interface Appendable (Code) | | An object to which char sequences and values can be appended. The
Appendable interface must be implemented by any class whose
instances are intended to receive formatted output from a
java.util.Formatter .
The characters to be appended should be valid Unicode characters as
described in Unicode Character
Representation. Note that supplementary characters may be composed of
multiple 16-bit char values.
Appendables are not necessarily safe for multithreaded access. Thread
safety is the responsibility of classes that extend and implement this
interface.
Since this interface may be implemented by existing classes
with different styles of error handling there is no guarantee that
errors will be propagated to the invoker.

| Method Summary | |
| Appendable | append(CharSequence csq)
Appends the specified character sequence to this Appendable.
Depending on which class implements the character sequence
csq, the entire sequence may not be appended. | | Appendable | append(CharSequence csq, int start, int end)
Appends a subsequence of the specified character sequence to this
Appendable.
An invocation of this method of the form out.append(csq, start,
end) when csq is not null, behaves in
exactly the same way as the invocation
out.append(csq.subSequence(start, end))
Parameters:
csq - The character sequence from which a subsequence will beappended. | | Appendable | append(char c)
Appends the specified character to this Appendable. |
| append | | Appendable append(CharSequence csq) throws IOException(Code) | | Appends the specified character sequence to this Appendable.
Depending on which class implements the character sequence
csq, the entire sequence may not be appended. For
instance, if csq is a
java.nio.CharBuffer then
the subsequence to append is defined by the buffer's position and limit.
Parameters:
csq - The character sequence to append. If csq isnull, then the four characters "null" areappended to this Appendable. A reference to this Appendable
throws:
IOException - If an I/O error occurs |
| append | | Appendable append(CharSequence csq, int start, int end) throws IOException(Code) | | Appends a subsequence of the specified character sequence to this
Appendable.
An invocation of this method of the form out.append(csq, start,
end) when csq is not null, behaves in
exactly the same way as the invocation
out.append(csq.subSequence(start, end))
Parameters:
csq - The character sequence from which a subsequence will beappended. If csq is null, then characterswill be appended as if csq contained the fourcharacters "null".
Parameters:
start - The index of the first character in the subsequence
Parameters:
end - The index of the character following the last character in thesubsequence A reference to this Appendable
throws:
IndexOutOfBoundsException - If start or end are negative, startis greater than end, or end is greater thancsq.length()
throws:
IOException - If an I/O error occurs |
| append | | Appendable append(char c) throws IOException(Code) | | Appends the specified character to this Appendable.
Parameters:
c - The character to append A reference to this Appendable
throws:
IOException - If an I/O error occurs |
