Method Details

charset

public TextCollector charset(Charset charset)

Sets the charset to be used if feed(ManagedBuffer) is invoked with ManagedBuffer<ByteBuffer>.

Defaults to UTF-8. Must be set before the first invocation of feed(ManagedBuffer).

Parameters:

charset - the charset

Returns:

the managed buffer reader

nativeCharset

public TextCollector nativeCharset()

Sets the charset to be used if feed(ManagedBuffer) is invoked with ManagedBuffer<ByteBuffer> to the charset specified as system property native.encoding.

If this property does not specify a valid charset, Charset.defaultCharset() is used.

Must be invoked before the first invocation of feed(ManagedBuffer).

Returns:

the managed buffer reader

maximumSize

public TextCollector maximumSize(int maximumLength)

Configures the maximum length of the collected text.

Input exceeding this size will be discarded.

Parameters:

maximumLength - the maximum length

Returns:

the maximum size

consumer

public TextCollector consumer(Consumer<String> consumer)

Configures a consumer for the collected text.

The consumer is invoked once when the complete text is available.

Parameters:

consumer - the consumer

Returns:

the line collector

feed

public <W extends Buffer> void feed(W buffer)

Feed data to the collector.

Calling this method with null as argument closes the feed.

Parameters:

buffer - the buffer

feed

public <W extends Buffer> void feed(ManagedBuffer<W> buffer)

Feed data to the collector.

Calling this method with null as argument closes the feed.

Specified by:

feed in interface InputConsumer

Parameters:

buffer - the buffer

eof

public boolean eof()

Checks if more input may become available.

Returns:

true, if successful
