Structure-based synchronization

Specialized toolkits - release 4.3.1.0-i20200220 > com.ibm.streams.teda 2.3.1 > com.ibm.streams.teda.parser.binary > StructureParse > Structure Definition Document > Structure-based synchronization

This optional section in the Structure Definition Document specifies the structure or structures that are searched in the binary data stream after a detection problem. The conditions that are specified for these structures detect a valid synchronization point.

The algorithm iterates byte-by-byte through the binary data stream and evaluates all conditions. If any conditions are met, a new synchronization point is detected, and normal processing is resumed.

Group conditions, which access only variables, are not evaluated. After a detection problem, all variables are reset to their initial values.

Example: The condition of the header structure is evaluated for every byte in the binary data stream until the condition is met.
