func (*LkkArray) ArrayKeyExists 

func (ka *LkkArray) ArrayKeyExists(key interface{}, arr interface{}) bool

ArrayKeyExists 检查arr(数组/切片/字典/结构体)里是否有key指定的键名(索引/字段).

func (*LkkArray) ArrayKeys 

func (ka *LkkArray) ArrayKeys(arr interface{}) []interface{}

ArrayKeys 返回数组(切片/字典/结构体)中所有的键名;如果是结构体,只返回公开的字段.

func (*LkkArray) ArrayPad 

func (ka *LkkArray) ArrayPad(arr interface{}, size int, item interface{}) []interface{}

ArrayPad 以指定长度将一个值item填充进arr数组/切片. 若 size 为正，则填补到数组的右侧，如果为负则从左侧开始填补; 若 size 的绝对值小于或等于 arr 数组的长度则没有任何填补.

func (*LkkArray) ArrayRand 

func (ka *LkkArray) ArrayRand(arr interface{}, num int) []interface{}

ArrayRand 从数组(切片/字典)中随机取出num个元素.

func (*LkkArray) ArrayReverse 

func (ka *LkkArray) ArrayReverse(arr interface{}) []interface{}

ArrayReverse 返回单元顺序相反的数组(仅限数组和切片).

func (*LkkArray) ArraySearchItem 

func (ka *LkkArray) ArraySearchItem(arr interface{}, condition map[string]interface{}) (res interface{})

ArraySearchItem 从数组(切片/字典)中搜索对应元素(单个). arr为要查找的数组,元素必须为字典/结构体;condition为条件字典.

func (ka *LkkArray) ArraySearchMutil(arr interface{}, condition map[string]interface{}) (res []interface{})

ArraySearchMutil 从数组(切片/字典)中搜索对应元素(多个). arr为要查找的数组,元素必须为字典/结构体;condition为条件字典.

func (*LkkArray) ArrayShuffle added in v0.1.5 

func (ka *LkkArray) ArrayShuffle(arr interface{}) []interface{}

ArrayShuffle 打乱数组/切片排序.

func (*LkkArray) ArrayUnique 

func (ka *LkkArray) ArrayUnique(arr interface{}) map[interface{}]interface{}

ArrayUnique 移除数组(切片/字典)中重复的值,返回字典,保留键名.

func (*LkkArray) ArrayValues 

func (ka *LkkArray) ArrayValues(arr interface{}, filterZero bool) []interface{}

ArrayValues 返回arr(数组/切片/字典/结构体)中所有的值;如果是结构体,只返回公开字段的值. filterZero 是否过滤零值元素(nil,false,0,"",[]),true时排除零值元素,false时保留零值元素.

func (*LkkArray) CopyStruct added in v0.2.8 

func (ka *LkkArray) CopyStruct(dest interface{}, resources ...interface{}) (err error)

CopyStruct 将resources的值拷贝到dest目标结构体; 要求dest必须是结构体指针,resources为多个源结构体;若resources存在多个相同字段的元素,结果以最后的为准; 只简单核对字段名,不做深层校验处理,需开发者自行检查dest和resources字段类型符合才可操作.

func (*LkkArray) CutSlice added in v0.1.5 

func (ka *LkkArray) CutSlice(arr interface{}, offset, size int) []interface{}

CutSlice 裁剪切片,返回根据offset(起始位置)和size(数量)参数所指定的arr(数组/切片)中的一段切片.
