- Method Detail
  - name
```
public final String name()
```
    The name of the table.
    
    Returns:
    
    The name of the table.
  - createTime
```
public final Instant createTime()
```
    The time that the table was created.
    
    Returns:
    
    The time that the table was created.
  - lastAccessTime
```
public final Instant lastAccessTime()
```
    The last time the table was accessed.
    
    Returns:
    
    The last time the table was accessed.
  - tableType
```
public final String tableType()
```
    The type of table. In Athena, only EXTERNAL_TABLE is supported.
    
    Returns:
    
    The type of table. In Athena, only EXTERNAL_TABLE is supported.
  - hasColumns
```
public final boolean hasColumns()
```
    For responses, this returns true if the service returned a value for the Columns property. This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified.
  - columns
```
public final List<Column> columns()
```
    A list of the columns in the table.
    
    Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.
    
    This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasColumns() method.
    
    Returns:
    
    A list of the columns in the table.
  - hasPartitionKeys
```
public final boolean hasPartitionKeys()
```
    For responses, this returns true if the service returned a value for the PartitionKeys property. This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified.
  - partitionKeys
```
public final List<Column> partitionKeys()
```
    A list of the partition keys in the table.
    
    Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.
    
    This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasPartitionKeys() method.
    
    Returns:
    
    A list of the partition keys in the table.
  - hasParameters
```
public final boolean hasParameters()
```
    For responses, this returns true if the service returned a value for the Parameters property. This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified.
  - parameters
```
public final Map<String,String> parameters()
```
    A set of custom key/value pairs for table properties.
    
    Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.
    
    This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasParameters() method.
    
    Returns:
    
    A set of custom key/value pairs for table properties.
  - toBuilder

```
    Specified by:

```
  - serializableBuilderClass
```
public static Class<? extends TableMetadata.Builder> serializableBuilderClass()

```
    Overrides:
    
    hashCode in class Object
  - equals
```
public final boolean equals(Object obj)

```
    Specified by:
    
    equalsBySdkFields in interface SdkPojo
  - toString
```
public final String toString()
```
    Returns a string representation of this object. This is useful for testing and debugging. Sensitive data will be redacted from this string using a placeholder value.
    
    Overrides:
    
    toString in class Object
  - getValueForField
```
