Method Detail

get

public WriterOutputStream get()
                       throws java.io.IOException

Builds a new WriterOutputStream.

You must set input that supports AbstractStreamBuilder.getWriter() on this builder, otherwise, this method throws an exception.

This builder use the following aspects:

• AbstractStreamBuilder.getWriter()
• AbstractStreamBuilder.getBufferSize()
• charsetDecoder
• writeImmediately

Returns:

a new instance.

Throws:

java.lang.UnsupportedOperationException - if the origin cannot provide a Writer.

java.io.IOException - if an I/O error occurs.

setCharset

public WriterOutputStream.Builder setCharset(java.nio.charset.Charset charset)

Description copied from class: AbstractStreamBuilder

Sets the Charset.

Subclasses may ignore this setting.

Overrides:

setCharset in class AbstractStreamBuilder<WriterOutputStream,WriterOutputStream.Builder>

Parameters:

charset - the Charset, null resets to the default.

Returns:

this.

setCharset

public WriterOutputStream.Builder setCharset(java.lang.String charset)

Description copied from class: AbstractStreamBuilder

Sets the Charset.

Subclasses may ignore this setting.

Overrides:

setCharset in class AbstractStreamBuilder<WriterOutputStream,WriterOutputStream.Builder>

Parameters:

charset - the Charset name, null resets to the default.

Returns:

this.

setCharsetDecoder

public WriterOutputStream.Builder setCharsetDecoder(java.nio.charset.CharsetDecoder charsetDecoder)

Sets the charset decoder.

Parameters:

charsetDecoder - the charset decoder.

Returns:

this

setWriteImmediately

public WriterOutputStream.Builder setWriteImmediately(boolean writeImmediately)

Sets whether the output buffer will be flushed after each write operation (true), i.e. all available data will be written to the underlying Writer immediately. If false, the output buffer will only be flushed when it overflows or when WriterOutputStream.flush() or WriterOutputStream.close() is called.

Parameters:

writeImmediately - If true the output buffer will be flushed after each write operation, i.e. all available data will be written to the underlying Writer immediately. If false, the output buffer will only be flushed when it overflows or when WriterOutputStream.flush() or WriterOutputStream.close() is called.

Returns:

this
