Ensures that the size of the string and object token tables are appended to the stream and that their offset is written into the first 4 bytes of the stream. Does nothing if the stream is not seekable or the constructor specified not to store presize information. Notes: Called automatically by ToArray() otherwise must be called manually.

Closes the current BinaryWriter and the underlying stream.

Dumps the type usage.

Determines whether the specified object is equal to the current object.

Serves as the default hash function.

Allows any object implementing IOwnedDataSerializable to serialize itself into this SerializationWriter. A context may also be used to give the object an indication of what data to store. As an example, using a BitVector32 gives a list of flags and the object can conditionally store data depending on those flags.

Writes a non-null generic List into the stream.

Writes a non-null generic Dictionary into the stream.

Writes a byte[] directly into the stream. The size of the array is not stored so only use this method when the number of bytes will be known at deserialization time. A null value will throw an exception

Writes a Nullable type into the stream. Synonym for WriteObject().

Stores an object into the stream using the fewest number of bytes possible. Stored Size: 1 byte upwards depending on type and/or content. 1 byte: null, DBNull.Value, Boolean 1 to 2 bytes: Int16, UInt16, Byte, SByte, Char, 1 to 4 bytes: Int32, UInt32, Single, BitVector32 1 to 8 bytes: DateTime, TimeSpan, Double, Int64, UInt64 1 or 16 bytes: Guid 1 plus content: string, object[], byte[], char[], BitArray, Type, ArrayList Any other object be stored using a .Net Binary formatter but this should only be allowed as a last resort: Since this is effectively a different serialization session, there is a possibility of the same shared object being serialized twice or, if the object has a reference directly or indirectly back to the parent object, there is a risk of looping which will throw an exception. The type of object is checked with the most common types being checked first. Each 'section' can be reordered to provide optimum speed but the check for null should always be first and the default serialization always last. Once the type is identified, a SerializedType byte is stored in the stream followed by the data for the object (certain types/values may not require storage of data as the SerializedType may imply the value). For certain objects, if the value is within a certain range then optimized storage may be used. If the value doesn't meet the required optimization criteria then the value is stored directly. The checks for optimization may be disabled by setting the OptimizeForSize property to false in which case the value is stored directly. This could result in a slightly larger stream but there will be a speed increate to compensate.

Writes an optimized Boolean[] into the stream using the fewest possible bytes. Notes: A null or empty array will take 1 byte. Stored as a BitArray.

Writes a BitVector32 into the stream using the fewest number of bytes possible. Stored Size: 1 to 4 bytes. (.Net is 4 bytes) 1 to 7 bits takes 1 byte 8 to 14 bits takes 2 bytes 15 to 21 bits takes 3 bytes 22 to 28 bits takes 4 bytes ------------------------------------------------------------------- 29 to 32 bits takes 5 bytes - use Write(BitVector32) method instead Try to order the BitVector32 masks so that the highest bits are least-likely to be set.

Writes a DateTime value into the stream using the fewest number of bytes possible. Stored Size: 3 bytes to 7 bytes (.Net is 8 bytes) Notes: A DateTime containing only a date takes 3 bytes (except a .NET 2.0 Date with a specified DateTimeKind which will take a minimum of 5 bytes - no further optimization for this situation felt necessary since it is unlikely that a DateTimeKind would be specified without hh:mm also) Date plus hh:mm takes 5 bytes. Date plus hh:mm:ss takes 6 bytes. Date plus hh:mm:ss.fff takes 7 bytes.

Writes a DateTime[] into the stream using the fewest possible bytes. Notes: A null or empty array will take 1 byte.

Writes a string value into the stream using the fewest number of bytes possible. Stored Size: 1 byte upwards depending on string length Notes: Encodes null, Empty, 'Y', 'N', ' ' values as a single byte Any other single char string is stored as two bytes All other strings are stored in a string token list: The TypeCode representing the current string token list is written first (1 byte), followed by the string token itself (1-4 bytes) When the current string list has reached 128 values then a new string list is generated and that is used for generating future string tokens. This continues until the maximum number (128) of string lists is in use, after which the string lists are used in a round-robin fashion. By doing this, more lists are created with fewer items which allows a smaller token size to be used for more strings. The first 16,384 strings will use a 1 byte token. The next 2,097,152 strings will use a 2 byte token. (This should suffice for most uses!) The next 268,435,456 strings will use a 3 byte token. (My, that is a lot!!) The next 34,359,738,368 strings will use a 4 byte token. (only shown for completeness!!!)

Writes a TimeSpan value into the stream using the fewest number of bytes possible. Stored Size: 2 bytes to 8 bytes (.Net is 8 bytes) Notes: hh:mm (time) are always stored together and take 2 bytes. If seconds are present then 3 bytes unless (time) is not present in which case 2 bytes since the seconds are stored in the minutes position. If milliseconds are present then 4 bytes. In addition, if days are present they will add 1 to 4 bytes to the above.

Writes a TimeSpan[] into the stream using the fewest possible bytes. Notes: A null or empty array will take 1 byte.

Stores a non-null Type object into the stream. Stored Size: Depends on the length of the Type's name. If the type is a System type (mscorlib) then it is stored without assembly name information, otherwise the Type's AssemblyQualifiedName is used.

Writes a pair of object[] arrays into the stream using the fewest number of bytes possible. The arrays must not be null and must have the same length The first array's values are written optimized The second array's values are compared against the first and, where identical, will be stored using a single byte. Useful for storing entity data where there is a before-change and after-change set of value pairs and, typically, only a few of the values will have changed.

Writes a non-null string directly to the stream without tokenization.

Writes a token (an Int32 taking 1 to 4 bytes) into the stream that represents the object instance. The same token will always be used for the same object instance. The object will be serialized once and recreated at deserialization time. Calls to SerializationReader.ReadTokenizedObject() will retrieve the same object instance.

Writes a token (an Int32 taking 1 to 4 bytes) into the stream that represents the object instance. The same token will always be used for the same object instance. When recreateFromType is set to true, the object's Type will be stored and the object recreated using Activator.GetInstance with a parameterless contructor. This is useful for stateless, factory-type classes. When recreateFromType is set to false, the object will be serialized once and recreated at deserialization time. Calls to SerializationReader.ReadTokenizedObject() will retrieve the same object instance.

Writes a null or a typed array into the stream.
