Method Detail

configurationClass

protected java.lang.Class<BigQuerySchemaTransformWriteConfiguration> configurationClass()

Returns the expected class of the configuration.

Specified by:

configurationClass in class org.apache.beam.sdk.schemas.transforms.TypedSchemaTransformProvider<BigQuerySchemaTransformWriteConfiguration>

from

protected org.apache.beam.sdk.schemas.transforms.SchemaTransform from(BigQuerySchemaTransformWriteConfiguration configuration)

Returns the expected SchemaTransform of the configuration.

Specified by:

from in class org.apache.beam.sdk.schemas.transforms.TypedSchemaTransformProvider<BigQuerySchemaTransformWriteConfiguration>

identifier

public java.lang.String identifier()

Implementation of the TypedSchemaTransformProvider identifier method.

inputCollectionNames

public java.util.List<java.lang.String> inputCollectionNames()

Implementation of the TypedSchemaTransformProvider inputCollectionNames method. Since a single is expected, this returns a list with a single name.

outputCollectionNames

public java.util.List<java.lang.String> outputCollectionNames()

Implementation of the TypedSchemaTransformProvider outputCollectionNames method. Since no output is expected, this returns an empty list.
