标题: setSGq and getSGq 函數說明使用 [打印本页] 作者: XYX365 时间: 2015-9-22 15:23 标题: setSGq and getSGq 函數說明使用 Squiggle Arrow (~>) Operator
The squiggle arrow (~>) operator is a generalization of the arrow operator. It works the same way as an arrow operator when applied directly to an object, but it can also accept a list of such objects. It walks the list applying the arrow operator whenever it finds an atomic object.
The underlying functions for ~> operator are the setSGq and getSGq functions, which set and retrieve the value of an attribute or a property. For example,
setSGq(obj value prop) ; is equivalent to:
obj~>prop=value
a=getSGq(obj prop) ; is equivalent to:
a=obj~>prop
info=getSGq(cvId objType) ; is equivalent to:
info=cvId~>objType
setSGq(rect list(10:10 100:120) bBox) ; is equivalent to:
rect~>bBox=list(10:10 100:120) 作者: chrysalis 时间: 2015-9-22 17:21
文档里面没有找到getSGq和setSGq，只有putpropq和~>等价。
请问LZ这个说明是在哪儿找的？作者: XYX365 时间: 2015-9-23 08:36
