Fiddle::Closure::BlockCaller
Parent:Fiddle::Closure
扩展Fiddle :: Closure，以允许在一个块中构建闭包
公共类方法
new(ctype, args, abi = Fiddle::Function::DEFAULT, &block) Show source
描述
构建一个新的BlockCaller对象。
ctype是要返回的C类型
args已通过回调
abi是关闭的abi
如果在准备ffi_cif或ffi_prep_closure时出错，则会引发RuntimeError。
例
include Fiddle
cb = Closure::BlockCaller.new(TYPE_INT, [TYPE_INT]) do |one|
one
end
func = Function.new(cb, [TYPE_INT], TYPE_INT)调用超类方法Fiddle :: Closure.new
# File ext/fiddle/lib/fiddle/closure.rb, line 34
def initialize ctype, args, abi = Fiddle::Function::DEFAULT, &block
super(ctype, args, abi)
@block = block
end公共实例方法
call(*args) Show source
用args调用构造的BlockCaller
例如see :: new
# File ext/fiddle/lib/fiddle/closure.rb, line 43
def call *args
@block.call(*args)
