    size : number

    See source

    Number of tokens (styles, classes or other tokens) defined.

Methods

  • _canMergeFrom( other ) → boolean

    See source

    Used by _canMergeAttributesFrom to verify if the given attribute can be merged without conflicts into the attribute.

    This method is indirectly used by the DowncastWriter while down-casting an AttributeElement to merge it with other AttributeElement.

    Parameters

    other : this

    Returns

    boolean

  • _clone() → this

    See source

    Clones the attribute value.

    Returns

    this

  • _getConsumables( [ name ] ) → Array<string>

    See source

    Returns a list of consumables for the attribute. This includes related tokens (for example other forms of notation of the same style property).

    Could be filtered by the given token name (class name, style property, etc.).

    Parameters

    [ name ] : string

    Returns

    Array<string>

  • _getTokensMatch( tokenPattern, [ valuePattern ] ) → undefined | Array<string>

    See source

    Used by the Matcher to collect matching attribute tokens.

    Parameters

    tokenPattern : string | true | RegExp

    The matched token name pattern.

    [ valuePattern ] : string | true | RegExp

    The matched token value pattern.

    Returns

    undefined | Array<string>

    An array of matching tokens.

  • _isMatching( other ) → boolean

    See source

    Used by _canSubtractAttributesOf to verify if the given attribute can be fully subtracted from the attribute.

    This method is indirectly used by the DowncastWriter while down-casting an AttributeElement to unwrap the AttributeElement.

    Parameters

    other : this

    Returns

    boolean

  • _mergeFrom( other ) → void

    See source

    Used by _mergeAttributesFrom to merge a given attribute into the attribute.
