public sealed class Turing.Sheet
A Turing sheet, or two dimensional Turing tape.

Constructors

Sheet

#
public Sheet(IEnumerable<Instruction> instructions, string initialState)
Setup a new Turing sheet.
Parameters:
instructions (IEnumerable<Turing.Instruction>)Instructions.
initialState (string)Initial state value.

Properties

CaretX

#
public int CaretX { get; }
Gets the caret x index.

CaretY

#
public int CaretY { get; }
Gets the caret y index.

IsFinished

#
public bool IsFinished { get; }
Gets whether this machine is in a finished state. This only happens when a terminal instruction is executed, or when the machine gets into a state which has no instruction associated with it.

Iteration

#
public int Iteration { get; }
Gets the number of iterations this machine has gone through.

State

#
public string State { get; }
Gets the state the machine is in currently.

Indexers

this[]

#
public string this[int x, int y] { get; set; }
Gets or sets the contents of a position in the field.
Parameters:
x (int)X index.
y (int)Y index.

Methods

ClearSheet

#
public void ClearSheet()
Clear the sheet.

ComputeBounds

#
public bool ComputeBounds(out int x0, out int x1, out int y0, out int y1)
Gets the lowest and highest defined indices along both axes.
Parameters:
x0 (out int)
x1 (out int)
y0 (out int)
y1 (out int)
Returns: True if bounds were computed.

CopyBlock

#
public string[][] CopyBlock(int x0, int x1, int y0, int y1)
Clone an entire rectangular region of values.
Parameters:
x0 (int)
x1 (int)
y0 (int)
y1 (int)
Returns: Nested arrays with sheet values. The secondary arrays represent the rows.

CopyValues

#
public (int x, int y, string value)[] CopyValues()
Clone the current sheer layout into an array.
Returns: Array of sheet coordinates and values.

FillBlock

#
public void FillBlock(int x0, int x1, int y0, int y1, string value)
Assign a bunch of values to a rectangular block.
Parameters:
x0 (int)Inclusive first x index.
x1 (int)Exclusive last x index.
y0 (int)Inclusive first y index.
y1 (int)Exclusive last y index.
value (string)Value to assign to each position in the block.

Run

#
public void Run()
Perform a single iteration.

Run

#
public void Run(int iterations)
Perform a number of iterations.
Parameters:
iterations (int)Maximum iterations to compute.

SetCaret

#
public void SetCaret(int x, int y)
Set the caret to a specific index. You'd be well advised to not set the caret while the machine is running, but I'm not your mother.
Parameters:
x (int)X index.
y (int)Y index.

SetupSheet

#
public void SetupSheet(IEnumerable<(int x, int y, string value)> values)
Set a bunch of values en masse.
Parameters:
values (IEnumerable<(int x, int y, string value)>)Index+Content tuples.

ToString

#
public override string ToString()
Create a text-based table overview of the sheet.
Overrides: Object.ToString

TransferSheet

#
public void TransferSheet(Sheet source)
Copy all sheet cells from another Turing machine.
Parameters:
source (Turing.Sheet)Source machine.
