Description copied from class: ProgramInstruction

Allow this instruction 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.)

Specified by:

process in class ProgramInstruction

Throws:

BlockedException

TeiidComponentException

TeiidProcessingException

clone

public CreateCursorResultSetInstruction clone()

Returns a deep clone

Overrides:

clone in class ProgramInstruction

Returns:

shallow clone

toString

public String toString()

Overrides:

toString in class Object

getDescriptionProperties

public PlanNode getDescriptionProperties()

Specified by:

getDescriptionProperties in class ProgramInstruction

getCommand

public ProcessorPlan getCommand()

getMode

public CreateCursorResultSetInstruction.Mode getMode()

setUsesLocalTemp

public void setUsesLocalTemp(boolean b)

requiresTransaction

public Boolean requiresTransaction(boolean transactionalReads)

Overrides:

requiresTransaction in class ProgramInstruction
