NAME ^

JavaScript::Runtime - Runs contexts

DESCRIPTION ^

INTERFACE ^

CLASS METHODS

new ( $maxbytes )

Creates a new runtime object. The optional argument $maxbytes specifies the number of bytes that can be allocated before garbage collection is runned. If ommited it defaults to 1MB.

INSTANCE METHODS

create_context ()

Creates a new JavaScript::Context-object in the runtime.

set_interrupt_handler ( $handler )

Attaches an interrupt handler (a function that is called before each op is executed ) to the runtime. The argument $handler must be either a code-reference or the name of a subroutine in the calling package.

To remove the handler call this method with an undef as argument.

Note that attaching an interrupt handler to the runtime causes a slowdown in execution speed since we must execute some Perl code between each op.

In order to abort execution your handler should a false value (such as 0). All true values will continue execution. Any exceptions thrown by the handler are ignored and $@ is cleared.
