com.amazon.ion.impl.bin.utf8.Utf8StringEncoder

All Implemented Interfaces:

Closeable, AutoCloseable

public class Utf8StringEncoder
extends Object

Encodes Strings to UTF-8. Instances of this class are reusable but are NOT threadsafe. Instances are vended by Pool.getOrCreate(). encode(String) can be called any number of times. Users are expected to call Closeable.close() when the encoder is no longer needed.

Method Details

encode

public Utf8StringEncoder.Result encode(String text)

Encodes the provided String's text to UTF-8. Unlike String.getBytes(Charset), this method will not silently replace characters that cannot be encoded with a substitute character. Instead, it will throw an IllegalArgumentException. Some resources in the returned Utf8StringEncoder.Result may be reused across calls to this method. Consequently, callers should use the Result and discard it immediately.

Parameters:

text - A Java String to encode as UTF8 bytes.

Returns:

A Utf8StringEncoder.Result containing a byte array of UTF-8 bytes and encoded length.

Throws:

IllegalArgumentException - if the String cannot be encoded as UTF-8.

close

public void close()

Attempts to return this instance to the pool with which it is associated, if any. Do not continue to use this instance after calling this method.
