.\" way too many mistakes in technical documents.

.SH "NAME"
MooseX::Declare::Syntax::KeywordHandling \- Basic keyword functionality
.SH "VERSION"
.IX Header "VERSION"
version 0.43
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
This role provides the functionality common for all keyword handlers
in MooseX::Declare.
.SH "ATTRIBUTES"
.IX Header "ATTRIBUTES"
.SS "identifier"
.IX Subsection "identifier"
This is the name of the actual keyword. It is a required string that is in
the same format as a usual Perl identifier.
.SH "METHODS"
.IX Header "METHODS"
.SS "get_identifier"
.IX Subsection "get_identifier"
.Vb 1
\&  Str Object\->get_identifier ()
.Ve
.PP
Returns the name the handler will be setup under.
.SS "setup_for"
.IX Subsection "setup_for"
.Vb 1
\&  Object\->setup_for (ClassName $class, %args)
.Ve
.PP
This will setup the handler in the specified \f(CW$class\fR. The handler will
dispatch to the \*(L"parse_declaration\*(R" method when the keyword is used.
.PP
A normal code reference will also be exported into the calling namespace.
It will either be empty or, if a \f(CW\*(C`generate_export\*(C'\fR method is provided,
the return value of that method.
.SS "parse_declaration"
.IX Subsection "parse_declaration"
.Vb 1
\&  Object\->parse_declaration (Str $filename, HashRef $setup_args, @call_args)
.Ve
.PP
This simply creates a new context and passes it
to the \*(L"parse\*(R" method.
.SH "REQUIRED METHODS"
.IX Header "REQUIRED METHODS"
.SS "parse"
.IX Subsection "parse"
.Vb 1
\&  Object\->parse (Object $context)
.Ve
.PP
This method must implement the actual parsing of the keyword syntax.
