新手发问超简单问题,目前还处于研读范例码的阶段,边测边看结果来理解程序6 b/ x8 z7 q8 k; `) u, L
其中有一段如下
" e6 N# J3 g" J% T o" Cask turtles with [ infected? = true ]
% k: s5 ~3 _3 B; Z8 }) s我原本以为这句会回传『所有』infected? = true 的 turtle
5 G! p" T) d8 O# v但看结果似乎不是这样。& }: z u- d% Q1 s
% o( X: J# _% l
假设所有符合条件的有 5 笔6 r1 [! ?' X0 J+ T
有时候回传 1 笔,有时回传 3 笔,是不固定的" f2 t. D4 H7 j' |0 [
回头查语法定义5 ^0 l0 l: }7 d5 s3 r
with : u* X0 a" x/ ^. S6 b, K- P" z
agentset with [reporter]
0 G, M( O8 K2 u" M$ n6 _ XTakes two inputs: on the left, an agentset (usually "turtles" or "patches"). On the right, a boolean reporter. Reports a new agentset containing only those agents that reported true -- in other words, the agents satisfying the given condition.% G5 [" Y* A! M' M! s. N
它只说回传 agents satisfying the given condition
0 ?6 t: Q- u L; Z" v+ C是否 with 回传的是『符合条件』的数据,而不是『所有符合条件』的数据 ? . |; o$ W+ u* B* d& C( p' M4 o
) V* Z2 y0 b1 A* f$ h8 i/ }- ]
想确定一下4 K' S2 ~% P0 H
谢谢!5 m* n. B6 P5 T1 O
