Method Summary

Modifier and Type	Method	Description
static int	encodedUTF8Length(String st)	Java uses a Modified UTF-8 (see DataOutput.writeUTF(String)), and this method attempts to calculate the modified utf-8 length; this method only works when the utf-8 writing logic is java's modified utf-8 and will not work when normal utf-8 is written.

Method Details

sizeof

public static int sizeof(String value)

assumes UTF8

encodedUTF8Length

public static int encodedUTF8Length(String st)

Java uses a Modified UTF-8 (see DataOutput.writeUTF(String)), and this method attempts to calculate the modified utf-8 length; this method only works when the utf-8 writing logic is java's modified utf-8 and will not work when normal utf-8 is written. If normal utf-8 is written, then CBUtil.encodedUTF8Length(String) should be used instread of this one.
