# LaTeXML::Util::KeyVal(3pm)

support for keyvals

## NAME

`"LaTeXML::Util::KeyVal"` - support for keyvals

## DESCRIPTION

Provides a parser and representation of keyval pairs `"LaTeXML::KeyVal"` represents parameters handled by LaTeX's keyval package.

### Declarations

- "DefKeyVal($keyset,$key,$type);"

  Defines the type of value expected for the key `$key` when parsed in part of a KeyVal using `$keyset`.  `$type` would be something like 'any' or 'Number', but I'm still working on this.

### Accessors

- "KeyVal($arg,$key)"

  This is useful within constructors to access the value associated with `$key` in the argument `$arg`.

- "KeyVals($arg)"

  This is useful within constructors to extract all keyvalue pairs to assign all attributes.

### KeyVal Methods

- "$value = $keyval-\>getValue($key);"

  Return the value associated with `$key` in the `$keyval`.

- "@keyvals = $keyval-\>getKeyVals;"

  Return the hash reference containing the keys and values bound in the `$keyval`. Note that will only contain the last value for a given key, if they were repeated.

- "@keyvals = $keyval-\>getPairs;"

  Return the alternating keys and values bound in the `$keyval`. Note that this may contain multiple entries for a given key, if they were repeated.

- "$keyval-\>digestValues;"

  Return a new `"LaTeXML::KeyVals"` object with all values digested as appropriate.
