- Method Detail
  - schemaId
```
public final Integer schemaId()
```
    The unique identifier for this schema version within the Iceberg table's schema evolution history.
    
    Returns:
    
    The unique identifier for this schema version within the Iceberg table's schema evolution history.
  - hasIdentifierFieldIds
```
public final boolean hasIdentifierFieldIds()
```
    For responses, this returns true if the service returned a value for the IdentifierFieldIds 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.
  - identifierFieldIds
```
public final List<Integer> identifierFieldIds()
```
    The list of field identifiers that uniquely identify records in the table, used for row-level operations and deduplication.
    
    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 hasIdentifierFieldIds() method.
    
    Returns:
    
    The list of field identifiers that uniquely identify records in the table, used for row-level operations and deduplication.
  - type
```
public final IcebergStructTypeEnum type()
```
    The root type of the schema structure, typically "struct" for Iceberg table schemas.
    
    If the service returns an enum value that is not available in the current SDK version, type will return IcebergStructTypeEnum.UNKNOWN_TO_SDK_VERSION. The raw value returned by the service is available from typeAsString().
    
    Returns:
    
    The root type of the schema structure, typically "struct" for Iceberg table schemas.
    
    See Also:
    
    IcebergStructTypeEnum
  - typeAsString
```
public final String typeAsString()
```
    The root type of the schema structure, typically "struct" for Iceberg table schemas.
    
    If the service returns an enum value that is not available in the current SDK version, type will return IcebergStructTypeEnum.UNKNOWN_TO_SDK_VERSION. The raw value returned by the service is available from typeAsString().
    
    Returns:
    
    The root type of the schema structure, typically "struct" for Iceberg table schemas.
    
    See Also:

  - hasFields
```
public final boolean hasFields()
```
    For responses, this returns true if the service returned a value for the Fields 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.
  - fields
```
public final List<IcebergStructField> fields()
```
    The list of field definitions that make up the table schema, including field names, types, and metadata.
    
    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 hasFields() method.
    
    Returns:
    
    The list of field definitions that make up the table schema, including field names, types, and metadata.
