Method Details

whereFieldName

public <FieldT> Filter.Inner<T> whereFieldName(String fieldName,
 SerializableFunction<FieldT,Boolean> predicate)

Set a predicate based on the value of a field, where the field is specified by name.

whereFieldId

public <FieldT> Filter.Inner<T> whereFieldId(int fieldId,
 SerializableFunction<FieldT,Boolean> predicate)

Set a predicate based on the value of a field, where the field is specified by id.

whereFieldNames

public Filter.Inner<T> whereFieldNames(List<String> fieldNames,
 SerializableFunction<Row,Boolean> predicate)

Set a predicate based on the value of multipled fields, specified by name.

whereFieldIds

public Filter.Inner<T> whereFieldIds(List<Integer> fieldIds,
 SerializableFunction<Row,Boolean> predicate)

Set a predicate based on the value of multipled fields, specified by id.

expand

public PCollection<T> expand(PCollection<T> input)

Description copied from class: PTransform

Override this method to specify how this PTransform should be expanded on the given InputT.

NOTE: This method should not be called directly. Instead apply the PTransform should be applied to the InputT using the apply method.

Composite transforms, which are defined in terms of other transforms, should return the output of one of the composed transforms. Non-composite transforms, which do not apply any transforms internally, should return a new unbound output and register evaluators (via backend-specific registration methods).
