opensavvy.ktmongo.dsl.tree¶
Helpers to represent trees of data built bottom-up. Nodes become immutable when they become branches of another tree, and offer utilities for debugging (e.g. JSON representation in their toString implementation).
Users of the library are not expected to interact with this package in day-to-day operations.
However, contributors to the library, and users wanting to implement custom operators, should familiarize themselves with this package.
Types¶
AbstractBsonNode¶
abstract class AbstractBsonNode : Node, BsonNode
Utility implementation for BsonNode, which handles the context, toString representation and freezing.
AbstractCompoundBsonNode¶
abstract class AbstractCompoundBsonNode(context: BsonContext) : AbstractBsonNode, CompoundBsonNode
Abstract utility class to help implement CompoundBsonNode.
BsonNode¶
interface BsonNode : Node, BsonFieldWriteable
A node in the BSON AST.
CompoundBsonNode¶
interface CompoundBsonNode : BsonNode, CompoundNode<BsonNode>
A compound expression is an BsonNode that may have children.
CompoundNode¶
interface CompoundNode<N : Node>
A Node that combines multiple other nodes into a single node.
Node¶
interface Node
An element in an abstract tree.
