Methods

create

Instantiates a JavaScript engine adapter object.

my $engine = EJS::Template::JSAdapter->create();

If no argument is passed, an engine is selected from the available ones.

An explicit engine can also be specified. E.g.

my $je_engine = EJS::Template::JSAdapter->create('JE');
my $v8_engine = EJS::Template::JSAdapter->create('JavaScript::V8');

new

Creates an adapter object.

This method should be overridden, and a property named 'context' is expected to be set up.

package Some::Extended::JSAdapter;
use base 'EJS::Template::JSAdapter';

sub new {
    my ($class) = @_;
    my $context = Some::Underlying::JavaScript::Context->new();
    return bless {context => $context}, $class;
}

context

Retrieves the underlying context object.

bind

Binds variable mapping to JavaScript objects.

This method should be overridden in a way that it can be invoked like this:

$engine->bind({
    varname1 => $object1,
    funcname2 => sub {...},
    ...
});

eval

Evaluates a JavaScript code.

This method should be overridden in a way that it can be invoked like this:

$engine->eval('print("ok\n")');
