jdk.io.CharArrayWriter — clojure-interop/java.io 1.0.5

This class implements a character buffer that can be used as an Writer. The buffer automatically grows when data is written to the stream. The data can be retrieved using toCharArray() and toString().

Note: Invoking close() on this class has no effect, and methods of this class can be called after the stream has closed without generating an IOException.

->char-array-writer clj

(->char-array-writer)

(->char-array-writer initial-size)

Constructor.

Creates a new CharArrayWriter with the specified initial size.

initial-size - an int specifying the initial buffer size. - int

throws: java.lang.IllegalArgumentException - if initialSize is negative

append clj

(append this csq)

(append this csq start end)

Appends a subsequence of the specified character sequence to this writer.

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.write(csq.subSequence(start, end).toString())

csq - The character sequence from which a subsequence will be appended. If csq is null, then characters will be appended as if csq contained the four characters "null". - java.lang.CharSequence start - The index of the first character in the subsequence - int end - The index of the character following the last character in the subsequence - int

returns: This writer - java.io.CharArrayWriter

throws: java.lang.IndexOutOfBoundsException - If start or end are negative, start is greater than end, or end is greater than csq.length()

close clj

(close this)

Close the stream. This method does not release the buffer, since its contents might still be required. Note: Invoking this method in this class will have no effect.

flush clj

(flush this)

Flush the stream.

reset clj

(reset this)

Resets the buffer so that you can use it again without throwing away the already allocated buffer.

size clj

(size this)

Returns the current size of the buffer.

returns: an int representing the current size of the buffer. - int

to-char-array clj

(to-char-array this)

Returns a copy of the input data.

returns: an array of chars copied from the input data. - char[]

to-string clj

(to-string this)

Converts input data to a string.

returns: the string. - java.lang.String

write clj

(write this c)

(write this c off len)

Writes characters to the buffer.

c - the data to be written - char[] off - the start offset in the data - int len - the number of chars that are written - int

write-to clj

(write-to this out)

Writes the contents of the buffer to another character stream.

out - the output stream to write to - java.io.Writer

throws: java.io.IOException - If an I/O error occurs.
