    Properties

    display: boolean

    Whether the math is in display mode or inline mode

    generatorPool: GeneratorPool<N, T, D>

    The speech generators for this math item.

    inputData: OptionList

    Extra data needed by the input or output jax, as needed

    inputJax: InputJax<N, T, D>

    The input jax used to process the math

    isEscaped: boolean

    Whether this item is an escaped character or not

    math: string

    The string representing the expression to be processed

    metrics: Metrics

    The metric information at the location of the math (the em-size, scaling factor, etc.)

    root: MmlNode

    The internal format for this expression (once compiled)

    start: Location<N, T>

    The start and ending locations in the document of this expression

    toMathML: (node: MmlNode, math: MathItem<N, T, D>) => string

    The serialization visitor

    typesetRoot: N

    The typeset version of the expression (once typeset)

    Methods

    • Converts the expression by calling the render actions until the state matches the end state

      Parameters

      • document: MathDocument<N, T, D>

        The MathDocument in which the math resides

      • Optionalend: number

        The state to end rerendering at (default = LAST)

      Returns void

    • Removes the typeset version from the document, optionally replacing the original form of the expression and its delimiters.

      Parameters

      • restore: boolean

        True if the original version is to be restored

      Returns void

    • Reset the item to its unprocessed state

      Parameters

      • Optionalrestore: boolean

        True if the original form should be restored to the document when rolling back a typeset version

      Returns void

    • Sets the metric information for this expression

      Parameters

      • em: number

        The size of 1 em in pixels

      • ex: number

        The size of 1 ex in pixels

      • cwidth: number

        The container width in pixels

      • scale: number

        The scaling factor (unitless)

      Returns void

    • Set or return the current processing state of this expression, optionally restoring the document if rolling back an expression that has been added to the document.

      Parameters

      • Optionalstate: number

        The state to set for the expression

      • Optionalrestore: boolean

        True if the original form should be restored to the document when rolling back a typeset version

      Returns number

      The current state
