Rexsee API介绍：CallLog通话记录
?
rexseeCallLog对象，实现自定义数量的最近通话记录，自定义查询最近通话，读取记录数据库表的URI地址。。
?
【函数】JsonObjectArray get(int number)
【说明】获取指定数量的最近通话。
【返回】Json对象数组，使用eval('('+json+')')转换为JavaScript对象数组。
【参数】number：要获取的最近通话的数量。
【示例】
?
Html代码??
【函数】JsonObjectArray get(String type, int number)
【说明】获取值类型、指定数量的最近通话。
【返回】Json对象数组，使用eval('('+json+')')转换为JavaScript对象数组。
【参数】type：类型，"INCOMING"(数据库中为1)、"OUTGOING"(数据库中为2)或"MISSED"(数据库中为3)。
number：要获取的最近通话的数量。
【示例】
?
Html代码??
【函数】JsonArray getColumns()
【说明】获取通话记录数据表所有字段。
【返回】Json数组，使用eval('('+json+')')转换为JavaScript数组，注意，为了提高效率，调用get()或getData()时并不会返回其中所有字段。
【参数】无
【示例】
?
Html代码??
【函数】JsonObjectArray getData(String selection, int number)
【说明】获取自定义查询条件的最近通话。
【返回】Json对象数组，使用eval('('+json+')')转换为JavaScript对象数组。
【参数】selection：自定义查询条件，相当于SQL语句中的WHERE字句（不含单词WHERE）。
number：要获取的最近通话的数量。
【示例】
