IfcFlowDirectionEnum
类型定义
此枚举定义分发端口的流向。
对于基于管道的端口,方向是物理流方向。
对于基于风管的端口,方向是物理流方向。
li>对于承载电力的基于电缆的端口(包含热、中性、接地的电路),方向是从电源的来源(从配电盘到保护装置,再到开关到固定装置)。对于承载通信信号的基于电缆的端口,方向源自信号成形的位置,例如传感器。对于通信网络,方向来自上层网络主机,例如承载多台计算机(具有接收器端口)的路由器(具有源端口)。
IFC2.0中的新枚举。
Constant | Description |
---|---|
SOURCE | A flow source, where a substance flows out of the connection. |
SINK | A flow sink, where a substance flows into the connection. |
SOURCEANDSINK | Both a source and sink, where a substance flows both into and out of the connection simultaneously. |
NOTDEFINED | Undefined flow direction. |
EXPRESS Specification
TYPE IfcFlowDirectionEnum = ENUMERATION OF ( SOURCE, SINK, SOURCEANDSINK, NOTDEFINED); END_TYPE;
