Constructor Details

MemoryPointer

public MemoryPointer(Ruby runtime,
 RubyClass klass)

Method Details

createMemoryPointerClass

public static RubyClass createMemoryPointerClass(ThreadContext context,
 RubyModule FFI,
 RubyClass Pointer)

from_string

public static IRubyObject from_string(ThreadContext context,
 IRubyObject klass,
 IRubyObject s)

initialize

public final IRubyObject initialize(ThreadContext context,
 IRubyObject sizeArg,
 Block block)

initialize

public final IRubyObject initialize(ThreadContext context,
 IRubyObject sizeArg,
 IRubyObject count,
 Block block)

initialize

public final IRubyObject initialize(ThreadContext context,
 IRubyObject sizeArg,
 IRubyObject count,

 Block block)

toString

public final String toString()

Description copied from class: RubyObject

The default toString method is just a wrapper that calls the Ruby "to_s" method.

Overrides:

toString in class RubyObject

Returns:

string representation

op_equal

public IRubyObject op_equal(ThreadContext context,
 IRubyObject obj)

Description copied from class: RubyBasicObject

rb_obj_equal Will by default use identity equality to compare objects. This follows the Ruby semantics. The name of this method doesn't follow the convention because hierarchy problems

Specified by:

op_equal in interface IRubyObject

Overrides:

op_equal in class Pointer

free

public final IRubyObject free(ThreadContext context)

autorelease

public final IRubyObject autorelease(ThreadContext context,
 IRubyObject release)

autorelease_p

public final IRubyObject autorelease_p(ThreadContext context)
