Implemented types

• Comparable

Constructors

A1Partial(String? letters, int? digits, {bool columnAbsolute = false, bool rowAbsolute = false})

Create a A1Partial from letters or null, and digits or null

A1Partial.fromA1(A1 a1)

Create a A1Partial from an A1

factory

A1Partial.fromVector(int? column, int? row, {bool columnAbsolute = false, bool rowAbsolute = false})

Create a A1Partial from the partial vector

factory

Properties

a1 → A1?

If this partial has letters and digitis it get be returned as A1 otherwise a null is returned

no setter

column → int?

Return the column as a zero based int or null

no setter

columnAbsolute → bool

Whether the column reference is absolute ($)

final

digits → int?

digits of the A1 or null for all rows

final

down → A1Partial

utility for moving down

no setter

hashCode → int

The hash code for this object.

no setter, override

isAll → bool

if both letters and digits are null this selects all

no setter

isWholeColumn → bool

if this partial represents a whole column ie. no row specified

no setter

isWholeRow → bool

if this partial represents a whole row ie. no column specified

no setter

isWholeRowOrColumn → bool

if this partial represents either a whole row or column

no setter

left → A1Partial

utility for moving left

no setter

letters → String?

letters of the A1 or null for all columns

final

right → A1Partial

utility for moving right

no setter

row → int?

Return the row as a zero based int or null

no setter

rowAbsolute → bool

Whether the row reference is absolute ($)

final

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

up → A1Partial

utility for moving up

no setter

Methods

compareTo(dynamic other) → int

The real work in a A1Partial is deciding if it is bigger than another this is important for creation of a range to order the left and right side of the : or ...

override

goDown(int count) → A1Partial

adjust A1PArtial down by count

goLeft(int count) → A1Partial

adjust A1PArtial left by count

goRight(int count) → A1Partial

adjust A1PArtial right by count

goUp(int count) → A1Partial

adjust A1PArtial up by count

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

toString() → String

Show the A1Partial with null left as a blank string

override

vectorCopyWith({int? column, int? row, bool? columnAbsolute, bool? rowAbsolute}) → A1Partial

Utility for copying

Operators

operator <(A1Partial other) → bool

operator <=(A1Partial other) → bool

operator ==(Object other) → bool

If other is an A1Partial then compare letters/digits if it is an A1, try to see if this is castable as A1 and compare

override

operator >(A1Partial other) → bool

operator >=(A1Partial other) → bool

Static Properties

all ↔ A1Partial

Empty/all A1Partial

getter/setter pair

Static Methods

max(Iterable<A1Partial?> list) → A1Partial

Conveniance function for determining maximum of a list of partials

min(Iterable<A1Partial?> list) → A1Partial

Conveniance function for determining minimum of a list of partials

rangefromList(List<A1Partial?> listFrom, List<A1Partial?> listTo, {Object? tag, A1? anchor}) → A1Range

Conveniance function for determining range from a list of partials
