Development note

When you read a specification of pdic format, please care for data type of fields. The specification is written for C/C++/C# implementer on a X86 windows. Because Java don't have unsigned types, so please take care. Here is a comparison between C/C++/C# on windows and Java

a comparison of data types

Type	Windows	Java
byte	8	8
short	16	16
ushort	16	N.A.
int	32	32
uint	32	N.A.
long	32	64
ulong	32	N.A.
longlong	64	N.A.

We use long for both uint and ulong, and int for ushort.
