Method Summary

Public Methods
public

addCMD(cmd: Command)

public

Specialized implementation of isAvailable: Returns true if the ResourceCounter is the last engine (since it can count any command).

public

receive(commandList: Command[])

public

Return the string representation of this ResourceCounter.

Inherited Summary

From class BasicEngine
public
public

Return a new qubit as a list containing 1 qubit object (quantum register of size 1).

public

Allocate n qubits and return them as a quantum register, which is a list of qubit objects.

public

Deallocate a qubit (and sends the deallocation command down the pipeline).

public

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

Check if there is a compiler engine handling the meta tag

public
public

send(commandList: Command[])

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

Params:

NameTypeAttributeDescription
cmd Command

public isAvailable(cmd: Command): boolean source

Specialized implementation of isAvailable: Returns true if the ResourceCounter is the last engine (since it can count any command).

Override:

BasicEngine#isAvailable

Params:

NameTypeAttributeDescription
cmd Command

Command for which to check availability (all Commands can be counted).

Return:

boolean

true, unless the next engine cannot handle the Command (if there is a next engine).

public receive(commandList: Command[]) source

Override:

BasicEngine#receive

Params:

NameTypeAttributeDescription
commandList Command[]

public toString(): string source

Return the string representation of this ResourceCounter.

Return:

string

A summary (string) of resources used, including gates, number of calls, and max. number of qubits that were active at the same time.
