Module rtlola_parser::ast [−][src]
Expand description
This module contains the RtLolaAst data structures for the RTLola Language.
Every node in the abstract syntax tree is assigned a unique id and has a span referencing the node’s location in the specification.
Structs
ActivationCondition | An Ast node representing the declaration of a activation condition of a stream. |
CloseSpec | An Ast node representing the declaration of a close condition of a stream template |
Constant | An Ast node representing the declaration of a constant. |
Expression | The Ast representation of a stream expression |
FilterSpec | An Ast node representing the declaration of a filter condition of a stream template |
FunctionName | An Ast node representing the name of a called function and also the names of the arguments. |
Ident | This struct represents an identifier in the specification. For example the name of an Output or Input. |
Import | An Ast node representing the import of a module, which brings additional implemented functionality to a specification. The ‘math’ module, for example, adds pre-defined mathematical functions as the sine or cosine function. |
Input | An Ast node representing the declaration of an input stream. |
Literal | An Ast node representing the declaration of a literal |
NodeId | Every node in the Ast gets a unique id, represented by a 32bit unsigned integer. They are used in the later analysis phases to store information about Ast nodes. |
Output | An Ast node representing the declaration of an output stream. |
Parameter | An Ast node representing the declaration of a parameter of a parametrized stream. |
Parenthesis | An Ast node representing an opening or closing parenthesis. |
RtLolaAst | The root of a RTLola specification, consisting of stream and trigger declarations. Each declaration contains the id of the Ast node, a span, and declaration-specific components. |
SpawnSpec | An Ast node representing the declaration of a spawn condition of a stream template. |
Trigger | An Ast node representing the declaration of a trigger |
Type | An Ast node representing the declaration of a value type |
TypeDeclField | An Ast node representing the declaration of a field of a user-defined type. |
TypeDeclaration | An Ast node representing the declaration of a user-defined type. |
Enums
BinOp | An Ast node representing a binary operator. |
ExpressionKind | The Ast representation of a single expression |
LitKind | The Ast representation of literals |
Offset | Describes the operation used to access a stream with a offset |
StreamAccessKind | Describes the operation used to access a stream |
TimeUnit | Supported time unit for real time expressions |
TypeKind | Ast representation of the value type of a stream |
UnOp | An Ast node representing an unary operator. |
WindowOperation | The Ast representation of the different aggregation functions |
