构造器详细资料

StreamOperator

public StreamOperator()

StreamOperator

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

The constructor of StreamOperator with Params.

参数:

params - the initial Params.

方法详细资料

link

public <S extends StreamOperator<?>> S link(S next)

Link to another StreamOperator.

Link the next StreamOperator using this StreamOperator as its input.

For example:

 StreamOperator a = ...;
 StreamOperator b = ...;

 StreamOperator c = a.link(b)
 

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

类型参数:

S - type of StreamOperator returned

参数:

next - the linked StreamOperator

返回:

the linked next

linkFrom(StreamOperator[])

linkFrom

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

Link from others StreamOperator.

Link this object to StreamOperator using the StreamOperators as its input.

For example:

 StreamOperator a = ...;
 StreamOperator b = ...;
 StreamOperator c = ...;

 StreamOperator d = c.linkFrom(a, b)
 

The d in the above code is the same instance as StreamOperator 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 StreamOperator<?> fromTable(org.apache.flink.table.api.Table table)

create a new StreamOperator from table.

参数:

table - the input table

返回:

the new StreamOperator

checkAndGetFirst

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