A sequence expression object with references to child sequence expressions. A sequence expression is a side effect free computation returning a value (a query).
public abstract class SequenceExpression : SequenceComputation
Initializes a new SequenceExpression object with the given sequence expression type.
Checks the sequence computation for errors utilizing the given checking environment reports them by exception default behavior: check all the children(Inherited from SequenceComputation.)
|Children|| (Overrides SequenceComputation.Children.)|
|ChildrenBase|| (Inherited from SequenceComputation.)|
Enumerates all child sequence expression objects
Evaluates this sequence expression. Implemented by calling execute, every expression is a computation.
Executes this sequence computation.(Inherited from SequenceComputation.)
|GetLocalVariables(Dictionary<(Of <<'(SequenceVariable, SetValueType>)>>), List<(Of <<'(SequenceExpressionContainerConstructor>)>>))|
Collects all variables of the sequence expression tree into the variables dictionary, and all container constructors used into the constructors array.(Inherited from SequenceComputation.)
stores the sequence /expression unique id(Inherited from SequenceBase.)
returns the sequence /expresion id - every sequence /expression is assigned a unique id used in xgrs code generation for copies the old id is just taken over, does not cause problems as code is only generated once per defined sequence(Inherited from SequenceBase.)
The precedence of this operator. Zero is the highest priority, int.MaxValue the lowest. Used to add needed parentheses for printing sequences /expressions TODO: WTF? das ist im Parser genau umgekehrt implementiert!(Inherited from SequenceBase.)
|ReturnsValue|| (Overrides SequenceComputation.ReturnsValue.)|
The type of the sequence computation (e.g. Assignment or MethodCall)(Inherited from SequenceComputation.)
The type of the sequence expression (e.g. Variable or IsVisited)
sets for the very node the profiling flag (does not recurse)(Inherited from SequenceBase.)
sets for the node and all children, i.e. the entire tree the profiling flag(Inherited from SequenceBase.)
A string symbol representing this sequence /expression kind.(Inherited from SequenceBase.)
Returns the type of the sequence expression default behaviour: returns "boolean"(Overrides SequenceComputation.Type(SequenceCheckingEnvironment).)
