Detailed Description

A set of constraints that specifies the limits of the runtime's memory use. You must set the heap size before initializing the VM - the size cannot be adjusted after the VM is initialized.

If you are using threads then you should hold the V8::Locker lock while setting the stack limit and you must set a non-default stack limit separately for each thread.

ConfigureDefaults()

void ConfigureDefaults	(	uint64_t	physical_memory,
		uint64_t	virtual_memory_limit,
		uint32_t	number_of_processors
	)

Configures the constraints with reasonable default values based on the capabilities of the current device the VM is running on.

Parameters

physical_memory	The total amount of physical memory on the current device, in bytes.
virtual_memory_limit	The amount of virtual memory on the current device, in bytes, or zero, if there is no limit.
number_of_processors	The number of CPUs available on the current device.
