Class DowncastWriter (engine/view/downcastwriter~DowncastWriter)

`addClass( className, element )`

Adds specified class to the element.

writer.addClass( 'foo', linkElement );
writer.addClass( [ 'foo', 'bar' ], linkElement );

Parameters

className : Array.<String> | String
element : Element

`breakAttributes( positionOrRange ) → Position | Range`

Breaks attribute nodes at provided position or at boundaries of provided range. It breaks attribute elements inside up to a container element.

See source

In following examples  is a container,  and  are attribute nodes:

   <p>foo<b><u>bar{}</u></b></p> -> <p>foo<b><u>bar</u></b>[]</p>
   <p>foo<b><u>{}bar</u></b></p> -> <p>foo{}<b><u>bar</u></b></p>
   <p>foo<b><u>b{}ar</u></b></p> -> <p>foo<b><u>b</u></b>[]<b><u>ar</u></b></p>
   <p><b>fo{o</b><u>ba}r</u></p> -> <p><b>fo</b><b>o</b><u>ba</u><u>r</u></b></p>

Note: DocumentFragment is treated like a container.

Note: Difference between breakAttributes and breakContainer is that breakAttributes breaks all attribute elements that are ancestors of given position, up to the first encountered container element. breakContainer assumes that given position is directly in container element and breaks that container element.

Throws CKEditorError view-writer-invalid-range-container when start and end positions of a passed range are not placed inside same parent container.

Throws CKEditorError view-writer-cannot-break-empty-element when trying to break attributes inside EmptyElement.

Throws CKEditorError view-writer-cannot-break-ui-element when trying to break attributes inside UIElement.

Parameters

positionOrRange : Position | Range: Position where to break attribute elements.

Returns

Position | Range: New position or range, after breaking the attribute elements.

`breakContainer( position ) → Position`

Breaks container view element into two, at the given position. Position has to be directly inside container element and cannot be in root. Does not break if position is at the beginning or at the end of it's parent element.

See source

   <p>foo^bar</p> -> <p>foo</p><p>bar</p>
   <div><p>foo</p>^<p>bar</p></div> -> <div><p>foo</p></div><div><p>bar</p></div>
   <p>^foobar</p> -> ^<p>foobar</p>
   <p>foobar^</p> -> <p>foobar</p>^

Note: Difference between breakAttributes and breakContainer is that breakAttributes breaks all attribute elements that are ancestors of given position, up to the first encountered container element. breakContainer assumes that given position is directly in container element and breaks that container element.

Parameters

position : Position: Position where to break element.

Returns

Position: Position between broken elements. If element has not been broken, the returned position is placed either before it or after it.

`clear( range, element )`

Removes matching elements from given range.

`createSelection( [ selectable ], [ placeOrOffset ], [ options ] = { [options.backward], [options.fake], [options.label] } ) → Selection`

Creates new Selection instance.

See source

// Creates empty selection without ranges.
const selection = writer.createSelection();

// Creates selection at the given range.
const range = writer.createRange( start, end );
const selection = writer.createSelection( range );

// Creates selection at the given ranges
const ranges = [ writer.createRange( start1, end2 ), writer.createRange( star2, end2 ) ];
const selection = writer.createSelection( ranges );

// Creates selection from the other selection.
const otherSelection = writer.createSelection();
const selection = writer.createSelection( otherSelection );

// Creates selection from the document selection.
const selection = writer.createSelection( editor.editing.view.document.selection );

// Creates selection at the given position.
const position = writer.createPositionFromPath( root, path );
const selection = writer.createSelection( position );

// Creates collapsed selection at the position of given item and offset.
const paragraph = writer.createContainerElement( 'paragraph' );
const selection = writer.createSelection( paragraph, offset );

// Creates a range inside an element which starts before the
// first child of that element and ends after the last child of that element.
const selection = writer.createSelection( paragraph, 'in' );

// Creates a range on an item which starts before the item and ends
// just after the item.
const selection = writer.createSelection( paragraph, 'on' );

Selection's constructor allow passing additional options (backward, fake and label) as the last argument.

// Creates backward selection.
const selection = writer.createSelection( range, { backward: true } );

Fake selection does not render as browser native selection over selected elements and is hidden to the user. This way, no native selection UI artifacts are displayed to the user and selection over elements can be represented in other way, for example by applying proper CSS class.

Additionally fake's selection label can be provided. It will be used to describe fake selection in DOM (and be properly handled by screen readers).

// Creates fake selection with label.
const selection = writer.createSelection( range, { fake: true, label: 'foo' } );

Parameters

[ placeOrOffset ] : Number | 'before' | 'end' | 'after' | 'on' | 'in'

Offset or place when selectable is an Item.

[ options ] : Object

Parameters

property : Array.<String> | String
element : Element

`rename( newName, viewElement )`

Renames element by creating a copy of renamed element but with changed name and then moving contents of the old element to the new one. Keep in mind that this will invalidate all positions which has renamed element as a parent.

See source

New element has to be created because Element#tagName property in DOM is readonly.

Since this function creates a new element and removes the given one, the new element is returned to keep reference.

Parameters

newName : String: New name for element.
viewElement : ContainerElement: Element to be renamed.

`setAttribute( key, value, element )`

See source

Parameters

key : String | Symbol
value : *
element : Element

`setSelection( selectable, [ placeOrOffset ], [ options ] = { [options.backward], [options.fake], [options.label] } )`

Sets selection's ranges and direction to the specified location based on the given document selection, selection, position, item, range, an iterable of ranges or null.

See source

Usage:

// Sets selection to the given range.
const range = writer.createRange( start, end );
writer.setSelection( range );

// Sets backward selection to the given range.

writer.setSelection( range );

// Sets selection to given ranges.
const ranges = [ writer.createRange( start1, end2 ), writer.createRange( star2, end2 ) ];
writer.setSelection( range );

// Sets selection to the other selection.
const otherSelection = writer.createSelection();
writer.setSelection( otherSelection );

// Sets collapsed selection at the given position.
const position = writer.createPositionFromPath( root, path );
writer.setSelection( position );

// Sets collapsed selection at the position of given item and offset.
const paragraph = writer.createContainerElement( 'paragraph' );
writer.setSelection( paragraph, offset );

Creates a range inside an element which starts before the first child of that element and ends after the last child of that element.

writer.setSelection( paragraph, 'in' );

Creates a range on the item which starts before the item and ends just after the item.
