Method Detail

putByte

@CanIgnoreReturnValue
PrimitiveSink putByte(byte b)

Puts a byte into this sink.

Parameters:

b - a byte

Returns:

this instance

putBytes

@CanIgnoreReturnValue
PrimitiveSink putBytes(byte[] bytes)

Puts an array of bytes into this sink.

Parameters:

bytes - a byte array

Returns:

this instance

putBytes

@CanIgnoreReturnValue
PrimitiveSink putBytes(byte[] bytes,
                       int off,
                       int len)

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.

Parameters:

bytes - a byte array

off - the start offset in the array

len - the number of bytes to write

Returns:

this instance

Throws:

IndexOutOfBoundsException - if off < 0 or off + len > bytes.length or len < 0

putBytes

@CanIgnoreReturnValue
PrimitiveSink putBytes(ByteBuffer bytes)

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.

Parameters:

bytes - a byte buffer

Returns:

this instance

Since:

23.0

putShort

@CanIgnoreReturnValue
PrimitiveSink putShort(short s)

Puts a short into this sink.

putInt

@CanIgnoreReturnValue
PrimitiveSink putInt(int i)

Puts an int into this sink.

putLong

@CanIgnoreReturnValue
PrimitiveSink putLong(long l)

Puts a long into this sink.

putFloat

@CanIgnoreReturnValue
PrimitiveSink putFloat(float f)

Puts a float into this sink.

putDouble

@CanIgnoreReturnValue
PrimitiveSink putDouble(double d)

Puts a double into this sink.

putBoolean

@CanIgnoreReturnValue
PrimitiveSink putBoolean(boolean b)

Puts a boolean into this sink.

putChar

@CanIgnoreReturnValue
PrimitiveSink putChar(char c)

Puts a character into this sink.

putUnencodedChars

@CanIgnoreReturnValue
PrimitiveSink putUnencodedChars(CharSequence charSequence)

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(java.lang.CharSequence, java.nio.charset.Charset), usually with a charset of UTF-8. For other use cases, use putUnencodedChars.

Since:

15.0 (since 11.0 as putString(CharSequence))

putString

@CanIgnoreReturnValue
PrimitiveSink putString(CharSequence charSequence,
                        Charset charset)

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(java.lang.CharSequence), which is faster, produces the same output across Java releases, and processes every char in the input, even if some are invalid.
