gravitino.api.expressions.sorts.sort_orders.SortImpl¶

class gravitino.api.expressions.sorts.sort_orders.SortImpl(expression: Expression, direction: SortDirection, null_ordering: NullOrdering)¶

Bases: SortOrder

__init__(expression: Expression, direction: SortDirection, null_ordering: NullOrdering)¶: Initialize the SortImpl object.

Methods

`__init__`(expression, direction, null_ordering)	Initialize the SortImpl object.
`children`()	Returns the children expressions of this sort order.
`direction`()	Returns the sort direction.
`expression`()	Returns the sort expression.
`null_ordering`()	Returns the null ordering.
`references`()	Returns a list of fields or columns that are referenced by this expression.

Attributes

`EMPTY_EXPRESSION`	EMPTY_EXPRESSION is only used as an input when the default children method builds the result.
`EMPTY_NAMED_REFERENCE`	EMPTY_NAMED_REFERENCE is only used as an input when the default references method builds the result array to avoid repeatedly allocating an empty array.

EMPTY_EXPRESSION: List[Expression] = []¶: EMPTY_EXPRESSION is only used as an input when the default children method builds the result.

EMPTY_NAMED_REFERENCE: List[NamedReference] = []¶: EMPTY_NAMED_REFERENCE is only used as an input when the default references method builds the result array to avoid repeatedly allocating an empty array.

children() → List[Expression]¶: Returns the children expressions of this sort order.

direction() → SortDirection¶: Returns the sort direction.

expression() → Expression¶: Returns the sort expression.

null_ordering() → NullOrdering¶: Returns the null ordering.

references() → List[NamedReference]¶: Returns a list of fields or columns that are referenced by this expression.
