Properties

allDescendants → Iterable<AstNode>

Recursively returns all descendants of this node, e.g. its children, their children and so on. The tree will be pre-order traversed.

no setter, inherited

childNodes → Iterable<AstNode>

All direct children of this node.

no setter, override

first ↔ Token?

The first token that appears in this node. This information is not set for all nodes.

getter/setter pair, inherited

firstPosition → int

The first position of this entity, as an zero-based offset in the file it was read from.

no setter, inherited

hashCode → int

The hash code for this object.

no setter, inherited

hasSpan → bool

Whether this entity has a source span associated with it.

no setter, inherited

isAggregate → bool

Whether this function call is to an aggregate function, meaning that it will combine multiple rows from the input relation into one.

no setter, override

last ↔ Token?

The last token that appears in this node. This information is not set for all nodes.

getter/setter pair, inherited

lastPosition → int

The (exclusive) last index of this entity in the source.

no setter, inherited

name → String

The name of the function being called

final

nameToken ↔ Token?

getter/setter pair, override

optionalScope → ReferenceScope?

no setter, inherited

parameters ↔ FunctionParameters

getter/setter pair, override-getter

parent ↔ AstNode?

The parent of this node, or null if this is the root node. Will be set by the analyzer after the tree has been parsed.

getter/setter pair, inherited

parents → Iterable<AstNode>

Returns all parents of this node up to the root. If this node is the root, the iterable will be empty.

no setter, inherited

resolved ↔ Referencable?

The resolved reference, or null if it hasn't been resolved yet.

getter/setter pair, inherited

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

scope ↔ ReferenceScope

The ReferenceScope, which contains available tables, column references and functions for this node.

getter/setter pair, inherited

selfAndDescendants → Iterable<AstNode>

Returns an iterable that fields yields this node, followed by allDescendants.

no setter, inherited

selfAndParents → Iterable<AstNode>

Returns an iterable containing this node and all parents.

no setter, inherited

span → FileSpan?

The piece of text forming this syntactic entity.

no setter, inherited

statementScope → StatementScope

no setter, inherited

synthetic ↔ bool

Whether this entity is synthetic, meaning that it doesn't appear in the actual source.

getter/setter pair, inherited

Methods

accept<A, R>(AstVisitor<A, R> visitor, A arg) → R

Calls the appropriate method on the visitor to make it recognize this node.

override

acceptWithoutArg<R>(AstVisitor<void, R> visitor) → R

Like accept, but without an argument.

inherited

contentEquals(AstNode other) → bool

Whether the content of this node is equal to the other node of the same type. The "content" refers to anything stored only in this node, children are ignored.

inherited

enclosingOfType<T extends AstNode>() → T?

Finds the first element in selfAndParents of the type T.

inherited

isChildOf(AstNode other) → bool

inherited

meta<T>() → T?

Returns the metadata of type T that might have been set on this node, or null if none was found. Nodes can have arbitrary annotations on them set via setMeta and obtained via meta. This mechanism is used to, for instance, attach variable scopes to a subtree.

inherited

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

setMeta<T>(T value) → void

Sets the metadata of type T to the specified value. Nodes can have arbitrary annotations on them set via setMeta and obtained via meta. This mechanism is used to, for instance, attach variable scopes to a subtree.

inherited

setSpan(Token first, Token last) → void

Sets the AstNode.first and AstNode.last property in one go.

inherited

toString() → String

A string representation of this object.

inherited

transformChildren<A>(Transformer<A> transformer, A arg) → void

Transforms children of this node by invoking transformer with the argument arg.

override

Operators

operator ==(Object other) → bool

The equality operator.
