WindowFunctionInvocation class - sqlparser library

Constructors

WindowFunctionInvocation({required IdentifierToken function, required FunctionParameters parameters, OrderByBase? orderBy, Expression? filter, WindowDefinition? windowDefinition, String? windowName})

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
childNodes → Iterable<AstNode>: All direct children of this node.
no setteroverride
filter ↔ Expression?: getter/setter pairinherited
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
function → IdentifierToken: finalinherited
hashCode → int: The hash code for this object.
no setterinherited
hasSpan → bool: Whether this entity has a source span associated with it.
no setterinherited
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 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
length → int: Available on SyntacticEntity, provided by the SyntacticLengthExtension extension
The length of this entity, in characters.
no setter
name → String: The name of the function being called
no setterinherited
nameToken ↔ Token?: getter/setter pairinherited
optionalScope → ReferenceScope?: no setterinherited
orderBy ↔ OrderByBase?: getter/setter pairinherited
over → WindowDefinition?: no setter
parameters ↔ FunctionParameters: getter/setter pairinherited
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
resolved ↔ Referencable?: The resolved reference, or null if it hasn't been resolved yet.
getter/setter pairinherited
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
windowDefinition ↔ WindowDefinition?: The window definition as declared in the OVER clause in sql. If this aggregate expression didn't declare a window (e.g. it instead uses a window via a name declared in the surrounding SELECT statement), we're this field will be null. Either windowDefinition or windowName are null. The resolved WindowDefinition is available in over in either case.
getter/setter pair
windowName → String?: An aggregate expression can be written as OVER <window-name> instead of declaring its own windowDefinition. Either windowDefinition or windowName are null. The resolved WindowDefinition is available in over in either case.
final

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
expandParameters() → List<Typeable>: Available on SqlInvocation, provided by the ExpandParameters extension
Returns the expanded parameters of a function call.
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
toSql() → String: Available on AstNode, provided by the NodeToText extension
Obtains a textual representation for AST nodes.
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.
