Detailed Description

Utility methods for decoding bytes into String. Callers are responsible for extracting bytes (possibly using Unsafe methods), and checking remaining bytes. All other UTF-8 validity checks and codepoint conversion happen in this class.

highSurrogate()

static char com.google.protobuf.Utf8.DecodeUtil.highSurrogate ( int  codePoint )

inlinestaticprivate

Definition at line 1965 of file Utf8.java.

isNotTrailingByte()

static boolean com.google.protobuf.Utf8.DecodeUtil.isNotTrailingByte ( byte  b )

inlinestaticprivate

Definition at line 1956 of file Utf8.java.

isOneByte()

static boolean com.google.protobuf.Utf8.DecodeUtil.isOneByte ( byte  b )

inlinestaticprivate

Returns whether this is a single-byte codepoint (i.e., ASCII) with the form '0XXXXXXX'.

Definition at line 1886 of file Utf8.java.

isThreeBytes()

static boolean com.google.protobuf.Utf8.DecodeUtil.isThreeBytes ( byte  b )

inlinestaticprivate

Returns whether this is a three-byte codepoint with the form '110XXXXX'.

Definition at line 1896 of file Utf8.java.

isTwoBytes()

static boolean com.google.protobuf.Utf8.DecodeUtil.isTwoBytes ( byte  b )

inlinestaticprivate

Returns whether this is a two-byte codepoint with the form '10XXXXXX'.

Definition at line 1891 of file Utf8.java.

lowSurrogate()

static char com.google.protobuf.Utf8.DecodeUtil.lowSurrogate ( int  codePoint )

inlinestaticprivate

Definition at line 1970 of file Utf8.java.

trailingByteValue()

static int com.google.protobuf.Utf8.DecodeUtil.trailingByteValue ( byte  b )

inlinestaticprivate

Returns the actual value of the trailing byte (removes the prefix '10') for composition.
