Representations of digested objects.

## NAME

"LaTeXML::Core::Whatsit" - Representations of digested objects.

## DESCRIPTION

represents a digested object that can generate arbitrary elements in the XML Document. It extends LaTeXML::Core::Box.

### METHODS

Note that the font is stored in the data properties under 'font'.

  Returns the LaTeXML::Core::Definition responsible for creating `$whatsit`.

- "$value = $whatsit-\>getProperty($key);"

  Returns the value associated with `$key` in the `$whatsit`'s property list.

- "$whatsit-\>setProperty($key,$value);"

  Sets the `$value` associated with the `$key` in the `$whatsit`'s property list.

- "$props = $whatsit-\>getProperties();"

  Returns the hash of properties stored on this Whatsit. (Note that this hash is modifiable).

- "$props = $whatsit-\>setProperties(%keysvalues);"

  Sets several properties, like setProperty.

- "$list = $whatsit-\>getArg($n);"

  Returns the `$n`-th argument (starting from 1) for this `$whatsit`.

- "@args = $whatsit-\>getArgs;"
