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 setterinherited
-
as
↔ BaseSelectStatement
-
getter/setter pair
-
asToken
↔ Token?
-
getter/setter pair
-
childNodes
→ Iterable<AstNode>
-
All direct children of this node.
no setteroverride
-
columnNames
→ List<String>?
-
If this common table expression has explicit column names, e.g. with
cnt(x) AS (...)
, contains the column names (['x']
, in that case).
Otherwise null.
final
-
cteTableName
→ String
-
final
-
first
↔ Token?
-
The first token that appears in this node. This information is not set for
all nodes.
getter/setter pairinherited
-
firstPosition
→ int
-
The first position of this entity, as an zero-based offset in the file it
was read from.
no setterinherited
-
hashCode
→ int
-
The hash code for this object.
no setterinherited
-
hasSpan
→ bool
-
Whether this entity has a source span associated with it.
no setterinherited
-
last
↔ Token?
-
The last token that appears in this node. This information is not set for
all nodes.
getter/setter pairinherited
-
lastPosition
→ int
-
The (exclusive) last index of this entity in the source.
no setterinherited
-
materializationHint
→ MaterializationHint?
-
final
-
materialized
↔ Token?
-
The
materialized
token, if there is any.
getter/setter pair
-
not
↔ Token?
-
The
not
token before the materialized
token, if there is any.
getter/setter pair
-
optionalScope
→ ReferenceScope?
-
no setterinherited
-
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 pairinherited
-
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 setterinherited
-
resolvedColumns
↔ List<Column>?
-
The columns that will be returned when evaluating this query.
getter/setter pairoverride-getter
-
resultSet
→ ResultSet
-
no setterinherited
-
runtimeType
→ Type
-
A representation of the runtime type of the object.
no setterinherited
-
scope
↔ ReferenceScope
-
The ReferenceScope, which contains available tables, column references
and functions for this node.
getter/setter pairinherited
-
selfAndDescendants
→ Iterable<AstNode>
-
Returns an iterable that fields yields this node, followed by
allDescendants.
no setterinherited
-
selfAndParents
→ Iterable<AstNode>
-
Returns an iterable containing
this
node and all parents.
no setterinherited
-
span
→ FileSpan?
-
The piece of text forming this syntactic entity.
no setterinherited
-
statementScope
→ StatementScope
-
no setterinherited
-
synthetic
↔ bool
-
Whether this entity is synthetic, meaning that it doesn't appear in the
actual source.
getter/setter pairinherited
-
tableNameToken
↔ IdentifierToken?
-
getter/setter pair
-
visibleToChildren
→ bool
-
Whether this referencable is still visible in child scopes. This doesn't
apply to many things, basically only to tables.
no setteroverride
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
-
findColumn(String name)
→ Column?
-
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
.
