Description copied from class: ProcessorInstruction

Allow this ProcessorInstruction to do whatever processing it needs, and to in turn manipulate the running program. A typical instruction should simply increment the program counter of the current program, but specialized instructions may add sub programs to the stack or not increment the counter (so that they are executed again.)

Overrides:

process in class WhileInstruction

Parameters:

env - instance of ProcessorEnvironment which is being used for the processing of the XML document model query

Throws:

BlockedException - if data is not available now but may be at a later time

TeiidComponentException - for non-business exception

TeiidProcessingException - for business exception due to user input or model
