Method Detail

hasWindowFn

boolean hasWindowFn()

 (Required) The SdkFunctionSpec of the UDF that assigns windows,
 merges windows, and shifts timestamps before they are
 combined according to the OutputTime.
 

.org.apache.beam.runner_api.v1.SdkFunctionSpec window_fn = 1;

getWindowFn

RunnerApi.SdkFunctionSpec getWindowFn()

 (Required) The SdkFunctionSpec of the UDF that assigns windows,
 merges windows, and shifts timestamps before they are
 combined according to the OutputTime.
 

.org.apache.beam.runner_api.v1.SdkFunctionSpec window_fn = 1;

getWindowFnOrBuilder

RunnerApi.SdkFunctionSpecOrBuilder getWindowFnOrBuilder()

 (Required) The SdkFunctionSpec of the UDF that assigns windows,
 merges windows, and shifts timestamps before they are
 combined according to the OutputTime.
 

.org.apache.beam.runner_api.v1.SdkFunctionSpec window_fn = 1;

getMergeStatusValue

int getMergeStatusValue()

 (Required) Whether or not the window fn is merging.
 This knowledge is required for many optimizations.
 

.org.apache.beam.runner_api.v1.MergeStatus.Enum merge_status = 2;

getMergeStatus

RunnerApi.MergeStatus.Enum getMergeStatus()

 (Required) Whether or not the window fn is merging.
 This knowledge is required for many optimizations.
 

.org.apache.beam.runner_api.v1.MergeStatus.Enum merge_status = 2;

getWindowCoderId

String getWindowCoderId()

 (Required) The coder for the windows of this PCollection.
 

string window_coder_id = 3;

getWindowCoderIdBytes

com.google.protobuf.ByteString getWindowCoderIdBytes()

 (Required) The coder for the windows of this PCollection.
 

string window_coder_id = 3;

hasTrigger

boolean hasTrigger()

 (Required) The trigger to use when grouping this PCollection.
 

.org.apache.beam.runner_api.v1.Trigger trigger = 4;

getTrigger

RunnerApi.Trigger getTrigger()

 (Required) The trigger to use when grouping this PCollection.
 

.org.apache.beam.runner_api.v1.Trigger trigger = 4;

getTriggerOrBuilder

RunnerApi.TriggerOrBuilder getTriggerOrBuilder()

 (Required) The trigger to use when grouping this PCollection.
 

.org.apache.beam.runner_api.v1.Trigger trigger = 4;

getAccumulationModeValue

int getAccumulationModeValue()

 (Required) The accumulation mode indicates whether new panes are a full
 replacement for prior panes or whether they are deltas to be combined
 with other panes (the combine should correspond to whatever the upstream
 grouping transform is).
 

.org.apache.beam.runner_api.v1.AccumulationMode.Enum accumulation_mode = 5;

 (Required) The accumulation mode indicates whether new panes are a full
 replacement for prior panes or whether they are deltas to be combined
 with other panes (the combine should correspond to whatever the upstream
 grouping transform is).
 

.org.apache.beam.runner_api.v1.AccumulationMode.Enum accumulation_mode = 5;

getOutputTimeValue

int getOutputTimeValue()

 (Required) The OutputTime specifies, for a grouping transform, how to
 compute the aggregate timestamp. The window_fn will first possibly shift
 it later, then the OutputTime takes the max, min, or ignores it and takes
 the end of window.
 This is actually only for input to grouping transforms, but since they
 may be introduced in runner-specific ways, it is carried along with the
 windowing strategy.

 it later, then the OutputTime takes the max, min, or ignores it and takes
 the end of window.
 This is actually only for input to grouping transforms, but since they
 may be introduced in runner-specific ways, it is carried along with the
 windowing strategy.
