PureExpressionNode

sealed class PureExpressionNode : ExpressionNode

Functions

abstract override fun copy(children: List<Node>): ExpressionNode

Returns a shallow copy of this node where the child nodes are replaced by children.

override fun toDocument(): Document

toDocumentWithMetadata

fun toDocumentWithMetadata(metadata: Metadata): Document

Returns a pretty representation of this Node where each descendant is decorated using metadata.

abstract fun toSurfaceNode(): ExpressionNode

override fun toSurfaceNode(metadata: Metadata): ExpressionNode

Returns a representation of this node in the surface syntax.

Properties

abstract override val children: Iterable<AtomicExpressionNode>

The list of all children nodes. This is empty for leaf nodes.

abstract val sourceLocation: SourceLocation

Inheritors

AtomicExpressionNode

OperatorApplicationNode

Extensions

fun Node.deepCopy(): Node

Like Node.copy, but recursively copies all descendant nodes also.

fun Node.descendants(): Sequence<Node>

Returns this node and all its descendants in post order.

descendantsIsInstance

inline fun <T : Node> Node.descendantsIsInstance(): Sequence<T>

Returns all instances of T contained in this node (which may include this node).

freshVariableNameGenerator

fun Node.freshVariableNameGenerator(): FreshNameGenerator

A FreshNameGenerator that will avoid all Variable names in this node.

involvedVariables

fun ExpressionNode.involvedVariables(): List<Variable>

fun ExpressionNode.readsFrom(nameAnalysis: NameAnalysis, protocols: Set<Protocol>): SelectionConstraint

States whether an expression reads only from the protocols in protocols.
