func DatabaseGenerator ¶
Types ¶
type Handler ¶
type Handler struct {
utils.JsonStandard
DBName string
DBPointer *sql.DB
Tables []string
InteTable uint8
RelaTable uint8
InfoTable uint8
RecordTables []uint16
DataShapes map[uint16]uint8
DataBuffer map[uint16]chan *Data
}
Handler is the main struct for the handler
func (*Handler) QueryFirstSynt ¶
QueryFirstSynt query the first time of the data Args:
id: the id of the data
Return:
time: the first time of the data
func (*Handler) QueryInfo ¶
QueryInfo query the information of the data Args:
id: the id of the data column: the column name of the data
Return:
para: the value of the column err: the error of the query
func (*Handler) QueryLastSynt ¶
QueryLastSynt query the last time of the data Args:
id: the id of the data
Return:
time: the last time of the data
func (*Handler) ReadRange ¶
func (handler *Handler) ReadRange(id uint16, start uint32, end uint32) ([]uint32, []uint64, [][]float64, error)
Read multiple rows of data from database
Args:
- id: data id
- start: start simulation timestamp
- end: end simulation timestamp
Return:
- simulation time 1D vector
- physical time 1D vector
- data matrix (2D)
- err: error
type TableInfo ¶
type TableInfo struct {
utils.JsonStandard
Id uint16 `json:"data_id"`
Name string `json:"data_name"`
Type uint16 `json:"data_type"`
Subtype1 uint16 `json:"data_subtype1"`
Subtype2 uint16 `json:"data_subtype2"`
Rate uint16 `json:"data_rate"`
Size uint16 `json:"data_size"`
Unit string `json:"data_unit"`
Notes string `json:"data_notes"`
}
TableInfo struct defines the structure of the data information table
func ReadDataInfo ¶
ReadDataInfo function reads the data information from the specified file path Args:
path: the path of the data information file
Returns:
dataList: the list of data information
