Public Methods

Method	Description
FloatToTerseString ( float val ) : string	Converts a floating point number to a terse string format used for transmitting numbers in wearable asset files
GetResourceStream ( string resourceName ) : System.IO.Stream	Attempts to load a file embedded in the assembly
GetResourceStream ( string resourceName, string searchPath ) : System.IO.Stream	Attempts to load a file either embedded in the assembly or found in a given search path
GlobalPosToRegionHandle ( float globalX, float globalY, float &localX, float &localY ) : ulong	Given an X/Y location in absolute (grid-relative) terms, a region handle is returned along with the local X/Y location in that region
InventoryCRC ( int creationDate, byte saleType, sbyte invType, sbyte type, UUID assetID, UUID groupID, int salePrice, UUID ownerID, UUID creatorID, UUID itemID, UUID folderID, uint everyoneMask, uint flags, uint nextOwnerMask, uint groupMask, uint ownerMask ) : uint	Calculates the CRC (cyclic redundancy check) needed to upload inventory.
OSDToPrimList ( StructuredData osd ) : List	Deserializes OSD in to a list of primitives
PrimListToOSD ( List prims ) : StructuredData.OSD	Converts a list of primitives to an object that can be serialized with the LLSD system
SplitBlocks ( OpenMetaverse.Packets.PacketBlock blocks, int packetOverhead ) : List
StateToAttachmentPoint ( uint state ) : AttachmentPoint
TEGlowByte ( float glow ) : byte
TEGlowFloat ( byte bytes, int pos ) : float
TEOffsetFloat ( byte bytes, int pos ) : float
TEOffsetShort ( float offset ) : short
TERotationFloat ( byte bytes, int pos ) : float
TERotationShort ( float rotation ) : short
ZeroDecode ( byte src, int srclen, byte dest ) : int	Decode a zerocoded byte array, used to decompress packets marked with the zerocoded flag Any time a zero is encountered, the next byte is a count of how many zeroes to expand. One zero is encoded with 0x00 0x01, two zeroes is 0x00 0x02, three zeroes is 0x00 0x03, etc. The first four bytes are copied directly to the output buffer.
ZeroEncode ( byte src, int srclen, byte dest ) : int	Encode a byte array with zerocoding. Used to compress packets marked with the zerocoded flag. Any zeroes in the array are compressed down to a single zero byte followed by a count of how many zeroes to expand out. A single zero becomes 0x00 0x01, two zeroes becomes 0x00 0x02, three zeroes becomes 0x00 0x03, etc. The first four bytes are copied directly to the output buffer.

Private Methods

Method	Description
FieldToString ( StringBuilder output, byte bytes, string fieldName ) : void	Convert a variable length field (byte array) to a string, with a field name prepended to each line of the output If the byte array has unprintable characters in it, a hex dump will be written instead
