@Beta @CanIgnoreReturnValue public interface PrimitiveSink {
Puts a byte into this sink.
Params:
  • b – a byte
Returns:this instance
/** * Puts a byte into this sink. * * @param b a byte * @return this instance */
PrimitiveSink putByte(byte b);
Puts an array of bytes into this sink.
Params:
  • bytes – a byte array
Returns:this instance
/** * Puts an array of bytes into this sink. * * @param bytes a byte array * @return this instance */
PrimitiveSink putBytes(byte[] bytes);
Puts a chunk of an array of bytes into this sink. bytes[off] is the first byte written, bytes[off + len - 1] is the last.
Params:
  • bytes – a byte array
  • off – the start offset in the array
  • len – the number of bytes to write
Throws:
Returns:this instance
/** * Puts a chunk of an array of bytes into this sink. {@code bytes[off]} is the first byte written, * {@code bytes[off + len - 1]} is the last. * * @param bytes a byte array * @param off the start offset in the array * @param len the number of bytes to write * @return this instance * @throws IndexOutOfBoundsException if {@code off < 0} or {@code off + len > bytes.length} or * {@code len < 0} */
PrimitiveSink putBytes(byte[] bytes, int off, int len);
Puts the remaining bytes of a byte buffer into this sink. bytes.position() is the first byte written, bytes.limit() - 1 is the last. The position of the buffer will be equal to the limit when this method returns.
Params:
  • bytes – a byte buffer
Returns:this instance
Since:23.0

Puts a short into this sink.
/** Puts a short into this sink. */

Puts an int into this sink.
/** Puts an int into this sink. */
PrimitiveSink putInt(int i);
Puts a long into this sink.
/** Puts a long into this sink. */

Puts a float into this sink.
/** Puts a float into this sink. */
PrimitiveSink putFloat(float f);
Puts a double into this sink.
/** Puts a double into this sink. */
PrimitiveSink putDouble(double d);
Puts a boolean into this sink.
/** Puts a boolean into this sink. */
PrimitiveSink putBoolean(boolean b);
Puts a character into this sink.
/** Puts a character into this sink. */
PrimitiveSink putChar(char c);
Puts each 16-bit code unit from the CharSequence into this sink.

Warning: This method will produce different output than most other languages do when running on the equivalent input. For cross-language compatibility, use putString, usually with a charset of UTF-8. For other use cases, use putUnencodedChars.

PrimitiveSink putUnencodedChars(CharSequence charSequence);
Puts a string into this sink using the given charset.

Warning: This method, which reencodes the input before processing it, is useful only for cross-language compatibility. For other use cases, prefer putUnencodedChars, which is faster, produces the same output across Java releases, and processes every char in the input, even if some are invalid.
