DatasetInfo (Google Cloud 0.90.0-alpha API)

java.lang.Object
- com.google.cloud.bigquery.DatasetInfo

All Implemented Interfaces:

Serializable

Direct Known Subclasses:

Dataset
```
public class DatasetInfo
extends Object
implements Serializable
```
Google BigQuery Dataset information. A dataset is a grouping mechanism that holds zero or more tables. Datasets are the lowest level unit of access control; you cannot control access at the table level.

- Method Detail
  - getDatasetId
```
public DatasetId getDatasetId()
```
    Returns the dataset identity.
  - getAcl
```
public List<Acl> getAcl()
```
    Returns the dataset's access control configuration.
    Update the ACLs for a dataset.
```
 Dataset dataset = bigquery.getDataset(DatasetId.of("my_dataset"));
 List<Acl> beforeAcls = dataset.getAcl();

 // Make a copy of the ACLs so that they can be modified.
 ArrayList<Acl> acls = new ArrayList<>(beforeAcls);
 acls.add(Acl.of(new Acl.User("sample.bigquery.dev@gmail.com"), Acl.Role.READER));
 Dataset.Builder builder = dataset.toBuilder();
 builder.setAcl(acls);

 bigquery.update(builder.build());  // API request.

  - getCreationTime
```
public Long getCreationTime()
```
    Returns the time when this dataset was created, in milliseconds since the epoch.
  - getDefaultTableLifetime
```
public Long getDefaultTableLifetime()
```
    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.
    Update the default table expiration time for a dataset.
```
 Dataset dataset = bigquery.getDataset(DatasetId.of("my_dataset"));
 Long beforeExpiration = dataset.getDefaultTableLifetime();

 Long oneDayMilliseconds = 24 * 60 * 60 * 1000L;
 Dataset.Builder builder = dataset.toBuilder();
 builder.setDefaultTableLifetime(oneDayMilliseconds);
 bigquery.update(builder.build());  // API request.
