| public com.android.dexgen.util.ByteArray | getBytes()Gets the UTF-8 value as UTF-8 encoded bytes.
return bytes;
|
| public java.lang.String | getString()Gets the UTF-8 value as a string.
The returned string is always already interned.
return string;
|
| public int | getUtf16Size()Gets the size of this instance as UTF-16 code points. That is,
get the number of 16-bit chars in the UTF-16 encoding of this
instance. This is the same as the {@code length} of the
Java {@code String} representation of this instance.
return string.length();
|
| public int | getUtf8Size()Gets the size of this instance as UTF-8 code points. That is,
get the number of bytes in the UTF-8 encoding of this instance.
return bytes.size();

| public int | hashCode(){@inheritDoc}
return string.hashCode();
|
| public boolean | isCategory2(){@inheritDoc}
return false;
|
| public static byte[] | stringToUtf8Bytes(java.lang.String string)Converts a string into its Java-style UTF-8 form. Java-style UTF-8
differs from normal UTF-8 in the handling of character '\0' and
surrogate pairs.
