NAME¶
"LaTeXML::Parameters" - formal parameters, including
"LaTeXML::Parameter".
DESCRIPTION¶
Provides a representation for the formal parameters of LaTeXML::Definitions:
- "LaTeXML::Parameter"
- represents an individual parameter.
Parameters Methods¶
- "$parameters =
parseParameters($prototype,$for);"
- Parses a string for a sequence of parameter specifications.
Each specification should be of the form
{} reads a regular TeX argument, a sequence of
tokens delimited by braces, or a single token.
{spec} reads a regular TeX argument, then reparses it
to match the given spec. The spec is parsed
recursively, but usually should correspond to
a single argument.
[spec] reads an LaTeX-style optional argument. If the
spec is of the form Default:stuff, then stuff
would be the default value.
Type Reads an argument of the given type, where either
Type has been declared, or there exists a ReadType
function accessible from LaTeXML::Package::Pool.
Type:value, or Type:value1:value2... These forms
pass additional Tokens to the reader function.
OptionalType Similar to Type, but it is not considered
an error if the reader returns undef.
SkipType Similar to OptionalType, but the value returned
from the reader is ignored, and does not occupy a
position in the arguments list.
- "@parameters =
$parameters->getParameters;"
- Return the list of "LaTeXML::Parameter" contained
in $parameters.
- "@tokens =
$parameters->revertArguments(@args);"
- Return a list of LaTeXML::Token that would represent the
arguments such that they can be parsed by the Gullet.
- "@args =
$parameters->readArguments($gullet,$fordefn);"
- Read the arguments according to this $parameters from the
$gullet. This takes into account any special forms of arguments, such as
optional, delimited, etc.
- "@args =
$parameters->readArgumentsAndDigest($stomach,$fordefn);"
- Reads and digests the arguments according to this
$parameters, in sequence. this method is used by Constructors.
