Method Detail

datasetId

public DatasetId datasetId()

Returns the dataset identity.

acl

public List<Acl> acl()

Returns the dataset's access control configuration.

Access Control

creationTime

public Long creationTime()

Returns the time when this dataset was created, in milliseconds since the epoch.

defaultTableLifetime

public Long defaultTableLifetime()

Returns the default lifetime of all tables in the dataset, in milliseconds. Once this property is set, all newly-created tables in the dataset will have an expirationTime property set to the creation time plus the value in this property, and changing the value will only affect new tables, not existing ones. When the expirationTime for a given table is reached, that table will be deleted automatically. If a table's expirationTime is modified or removed before the table expires, or if you provide an explicit expirationTime when creating a table, that value takes precedence over the default expiration time indicated by this property.

description

public String description()

Returns a user-friendly description for the dataset.

etag

public String etag()

Returns the hash of the dataset resource.

friendlyName

public String friendlyName()

Returns a user-friendly name for the dataset.

generatedId

public String generatedId()

Returns the service-generated id for the dataset.

lastModified

public Long lastModified()

Returns the time when this dataset or any of its tables was last modified, in milliseconds since the epoch.

location

public String location()

Returns the geographic location where the dataset should reside.

Dataset Location

selfLink

public String selfLink()

Returns an URL that can be used to access the resource again. The returned URL can be used for get or update requests.

toBuilder

public DatasetInfo.Builder toBuilder()

Returns a builder for the dataset object.

toString

public String toString()

Overrides:

toString in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

equals

public boolean equals(Object obj)

Overrides:

equals in class Object

builder

public static DatasetInfo.Builder builder(DatasetId datasetId)

Returns a builder for a DatasetInfo object given it's identity.

builder

public static DatasetInfo.Builder builder(String datasetId)

Returns a builder for a DatasetInfo object given it's user-defined id.

builder

public static DatasetInfo.Builder builder(String projectId,
                          String datasetId)

Returns a builder for the DatasetInfo object given it's user-defined project and dataset ids.
