D.2 LaTeXML::Util::KeyVal

Support for keyvals

D.2.1 Description

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

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.

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.

$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.
