The following table describes the fields of the List data block.

The eStreamer service uses the Generic List data block to encapsulate a list of data blocks. For example, 
the Host Profile data block contains information about multiple client applications and uses the Generic 
List block to embed a list of Client Application data blocks in the message. The Generic List data block 
has a block type of 3 in the series 2 group of blocks.

The following diagram shows the basic structure of a Generic List data block:

The following table describes the fields of the Generic List data block.

Block Type

uint32

Initiates a List data block. This value is always 

2

.

Block Length

uint32

Number of bytes in the List block and encapsulated data. For example, 
if there were three Sub-Server data blocks included in the list, the value 
here would include the total number of bytes in the Sub-Server blocks, 
plus eight bytes for the List block header.

Encapsulated 
Data Blocks

variable

Encapsulated data blocks up to the maximum number of bytes in the 
list block length.

Data Block Length uint32

Number of bytes in the Generic List block and encapsulated data 
blocks. This number includes the eight bytes of the generic list block 
header fields, plus the total number of bytes in all of the 
encapsulated data blocks.

Encapsulated Data 
Blocks

variable

Encapsulated data blocks up to the maximum number of bytes in the 
Generic List block length.
