Detailed Description

Wrapper to encrypt and store a value with obfuscated cache for performance.

A derived class should provide a simple algorithm to keep the obfuscated data in the memory.

Template Parameters

T	The value type.
U	The property type for editing, commonly use T or string.

Member Function Documentation

CryptoCache (T value = default) override void OnBeforeSerialize ( )

virtual

Initialize with the specified value.

Parameters

value

Value.

OnBeforeSerialize, write the obfuscated cache to the real value.

Reimplemented from CryptoValue< T, U >.

override void OnAfterDeserialize ( )

virtual

OnAfterDeserialize, read the real value to the obfuscated cache.

Reimplemented from CryptoValue< T, U >.

abstract T ReadObfuscated ( )

protectedpure virtual

Read the obfuscated cache value.

Returns

Value.

Implemented in CryptoDate, CryptoPeriod, CryptoFloat, CryptoAscii, CryptoBool, CryptoInt, and CryptoLong.
