Method Summary
Public Methods | ||
public |
isAvailable(cmd: Command): boolean Specialized implementation of isAvailable: Returns true if the CommandPrinter is the last engine (since it can print any command). |
|
public |
Print a command or, if the command is a measurement instruction and the CommandPrinter is the last engine in the engine pipeline: Query the user for the measurement result (if accept_input = true) / Set the result to 0 (if it's false). |
|
public |
Receive a list of commands from the previous engine, print the commands, and then send them on to the next engine. |

|
public |
allocateQubit(dirty: boolean): Qureg Return a new qubit as a list containing 1 qubit object (quantum register of size 1). |
|
public |
allocateQureg(n: number): Qureg Allocate n qubits and return them as a quantum register, which is a list of qubit objects. |
|
public |
deallocateQubit(qubit: BasicQubit) Deallocate a qubit (and sends the deallocation command down the pipeline). |
|
public |
isAvailable(cmd: Command): boolean Default implementation of isAvailable: Ask the next engine whether a command is available, i.e., whether it can be executed by the next engine(s). |
|
public |
isMetaTagSupported(metaTag: function): boolean Check if there is a compiler engine handling the meta tag |
|

|
public |
Forward the list of commands to the next engine in the pipeline. |

Override:
BasicEngine#constructorParams:
Name | Type | Attribute | Description |
acceptInput | boolean | If accept_input is true, the printer queries the user to input measurement results if the CommandPrinter is the last engine. Otherwise, all measurements yield |
|
defaultMeasure | boolean | Default measurement result (if accept_input is false). |
|
inPlace | boolean | If in_place is true, all output is written on the same line of the terminal. |

Name | Type | Attribute | Description |
cmd | Command | Command of which to check availability (all Commands can be printed). |
public printCMD(cmd: Command) source
Print a command or, if the command is a measurement instruction and the CommandPrinter is the last engine in the engine pipeline: Query the user for the measurement result (if accept_input = true) / Set the result to 0 (if it's false).
Params:
Name | Type | Attribute | Description |
