描述----------Description----------

Classes for temporal operators from OpenGIS(R) Filter Encoding used in filters in GetObservation requests.
班时间的运营商与OpenGIS（R）GetObservation请求中的过滤器中使用的过滤器编码。


用法----------Usage----------


TM_After(propertyName = sosDefaultTempOpPropertyName, time)
TM_Before(propertyName = sosDefaultTempOpPropertyName, time)
TM_During(propertyName = sosDefaultTempOpPropertyName, time)
TM_Equals(propertyName = sosDefaultTempOpPropertyName, time)



参数----------Arguments----------

参数：propertyName
The name of the property that is used to wrap the time.
名称的属性，用于包装的时间。


参数：time
A time instant or period to be used as the temporal operand.
甲时刻或期间要使用的作为颞操作数。


值----------Value----------

An object of the respective class, so TM_After, TM_Before, TM_During or TM_Equals
各自的类的对象，所以TM_After，TM_Before，TM_During或TM_Equals


类对象----------Objects from the Class----------

Objects can be created by calls of the form new("TM_After", ...).
可以创建对象通过调用的形式new("TM_After", ...)。


插槽----------Slots----------




time: Object of class "GmlTimeInstant" ~~
time：对象类"GmlTimeInstant"~~




propertyName: Object of class "character" ~~
propertyName：对象类"character"~~


扩展----------Extends----------

Class "OgcBinaryTemporalOp", directly. Class "OgcBinaryTemporalOpOrNULL", by class "OgcBinaryTemporalOp", distance 2.
类"OgcBinaryTemporalOp"，直接。类"OgcBinaryTemporalOpOrNULL"，类的“OgcBinaryTemporalOp”，距离2。


方法----------Methods----------

encodeXML signature(obj = "TM_After", sos = "SOS")...




show signature(object = "TM_After"): ...
显示signature(object = "TM_After")：...
