NAME
CodeGen::Cpppp::Template - Base class for template classes created by compiling cpppp
VERSION
version 0.002
DESCRIPTION
This is the base class for all Template classes compiled from cpppp source. It also defines the exports that set up the scope for evaluating the template.
EXPORTS
-setup-
Initializes @ISA to CodeGen::Cpppp::Template (unless it was already initialized) and sets the compiler flags for strict, warnings, utf8, lexical_subs, signatures, and postderef.
:v0-
Exports symbols
PUBLIC,PROTECTED,PRIVATE
ATTRIBUTES
context
Weak-reference to the instance of CodeGen::Cpppp which created this template, if any. This is automatically set by "new_template" in CodeGen::Cpppp. Read-only.
output
Instance of CodeGen::Cpppp::Output. Read-only.
current_output_section
Name of the section of output being written. Read-write.
CONSTRUCTOR
$tpl= $template_class->new(%params, %attrs);The constructor takes object attributes and user-defined template parameters. When specifying values for parameters, the type of the value must match the variable-type of the parameter, such as '@array' variables needing arrayref values.
Running the constructor immediately executes the body of the user's template, which may initialize variables and define subroutines, and likely also generate output. The subs declared in the template are then exposed as methods of this object. Calling those methods may generate additional output, which is all collected in the "output" object.
METHODS
coerce_parameters
my $params= $tpl_class->coerce_parameters(\%params);Given a hashref of potential parameter values, select and coerce the ones to match the actual parameters of this template. The keys of this hashref may be either the bare name of the parameter, or the name-with-sigil. This allows you to specify { '$x' => $scalar, '@x' => \@arrayref } and for some parameter named 'x' this method will select the one whose type matches rather than attempting to coerce the value.
flush
Make sure all output is written to the "output" object. Some output is buffered internally so that formatting (like autoindent) can be applied when a code block is complete.
define_template_macro
This is called during the template constructor to bind a user-defined macro to the lexical sub that implements it for this template instance.
define_template_method
This is called during the template constructor to bind the lexical subs of the template to methods of the object being created.
