append

open override fun append(csq: CharSequence?, start: Int, end: Int): Writer

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

{@snippet lang=java :

  • out.write(csq.subSequence(start, end).toString())
  • }

Return

This writer

Since

1.5

Parameters

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".

start

The index of the first character in the subsequence

end

The index of the character following the last character in the subsequence

Throws

If start or end are negative, start is greater than end, or end is greater than csq.length()

IOException

If an I/O error occurs


open override fun append(csq: CharSequence?): Writer

Appends the specified character sequence to this writer.

An invocation of this method of the form out.append(csq) when csq is not null, behaves in exactly the same way as the invocation

{@snippet lang=java :

  • out.write(csq.toString())
  • }

Depending on the specification of toString for the character sequence csq, the entire sequence may not be appended. For instance, invoking the toString method of a character buffer will return a subsequence whose content depends upon the buffer's position and limit.

Return

This writer

Since

1.5

Parameters

csq

The character sequence to append. If csq is null, then the four characters "null" are appended to this writer.

Throws

IOException

If an I/O error occurs
