构造器详细资料

BatchOperator

public BatchOperator()

BatchOperator

public BatchOperator(org.apache.flink.ml.api.misc.param.Params params)

The constructor of BatchOperator with Params.

参数:

params - the initial Params.

方法详细资料

link

public <B extends BatchOperator<?>> B link(B next)

Link to another BatchOperator.

Link the next BatchOperator using this BatchOperator as its input.

For example:

 BatchOperator a = ...;
 BatchOperator b = ...;
 BatchOperator c = a.link(b)
 

The BatchOperator c in the above code is the same instance as b which takes a as its input. Note that BatchOperator b will be changed to link from BatchOperator a.

类型参数:

B - type of BatchOperator returned

参数:

next - The operator that will be modified to add this operator to its input.

返回:

the linked next

linkFrom(BatchOperator[])

linkFrom

public abstract T linkFrom(BatchOperator<?>... inputs)

Link from others BatchOperator.

Link this object to BatchOperator using the BatchOperators as its input.

For example:

 BatchOperator a = ...;
 BatchOperator b = ...;
 BatchOperator c = ...;

 BatchOperator d = c.linkFrom(a, b)
 

The d in the above code is the same instance as BatchOperator c which takes both a and b as its input.

note: It is not recommended to linkFrom itself or linkFrom the same group inputs twice.

参数:

inputs - the linked inputs

返回:

the linked this object

fromTable

public static BatchOperator<?> fromTable(org.apache.flink.table.api.Table table)

create a new BatchOperator from table.

参数:

table - the input table

返回:

the new BatchOperator

checkAndGetFirst

protected static BatchOperator<?> checkAndGetFirst(BatchOperator<?>... inputs)
