get

public ReaderInputStream get()
                      throws java.io.IOException

Constructs a new instance.

This builder use the aspects Reader, Charset, CharsetEncoder, buffer size.

You must provide an origin that can be converted to a Reader by this builder, otherwise, this call will throw an UnsupportedOperationException.

Returns:

a new instance.

Throws:

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

java.lang.IllegalStateException - if the origin is null.

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

setCharset

public ReaderInputStream.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<ReaderInputStream,ReaderInputStream.Builder>

Parameters:

charset - the Charset, null resets to the default.

Returns:

this.

setCharsetEncoder

public ReaderInputStream.Builder setCharsetEncoder(java.nio.charset.CharsetEncoder newEncoder)

Sets the charset encoder. Assumes that the caller has configured the encoder.

Parameters:

newEncoder - the charset encoder, null resets to a default encoder.

Returns:

this
