toPOJO

public <T> List<T> toPOJO(QueryResult queryResult,
 Class<T> clazz)
                   throws CnosDBMapperException

Process a QueryResult object returned by the CnosDB client inspecting the internal data structure and creating the respective object instances based on the Class passed as parameter.

类型参数:

T - the target type

参数:

queryResult - the CnosDB result object

clazz - the Class that will be used to hold your measurement data

返回:

a List of objects from the same Class passed as parameter and sorted on the same order as received from CnosDB.

抛出:

CnosDBMapperException - If QueryResult parameter contain errors, clazz parameter is not annotated with @Measurement or it was not possible to define the values of your POJO (e.g. due to an unsupported field type).

toPOJO

public <T> List<T> toPOJO(QueryResult queryResult,
 Class<T> clazz,
 TimeUnit precision)
                   throws CnosDBMapperException

Process a QueryResult object returned by the CnosDB client inspecting the internal data structure and creating the respective object instances based on the Class passed as parameter.

类型参数:

T - the target type

参数:

queryResult - the CnosDB result object

clazz - the Class that will be used to hold your measurement data

precision - the time precision of results

返回:

a List of objects from the same Class passed as parameter and sorted on the same order as received from CnosDB.

抛出:

CnosDBMapperException - If QueryResult parameter contain errors, clazz parameter is not annotated with @Measurement or it was not possible to define the values of your POJO (e.g. due to an unsupported field type).

toPOJO

public <T> List<T> toPOJO(QueryResult queryResult,
 Class<T> clazz,
 String measurementName)
                   throws CnosDBMapperException

Process a QueryResult object returned by the CnosDB client inspecting the internal data structure and creating the respective object instances based on the Class passed as parameter.

类型参数:

T - the target type

参数:

queryResult - the CnosDB result object

clazz - the Class that will be used to hold your measurement data

measurementName - name of the Measurement

返回:

a List of objects from the same Class passed as parameter and sorted on the same order as received from CnosDB.

抛出:

CnosDBMapperException - If QueryResult parameter contain errors, clazz parameter is not annotated with @Measurement or it was not possible to define the values of your POJO (e.g. due to an unsupported field type).
