SequenceBase Class

The common base of sequence, sequence computation, and sequence expression objects, with some common infrastructure.
Inheritance Hierarchy

Namespace: de.unika.ipd.grGen.libGr
Assembly: libGr (in libGr.dll) Version: GrGen.NET 7.1
Syntax
C#
Copy
public abstract class SequenceBase

The SequenceBase type exposes the following members.

Constructors
 NameDescription
Protected methodSequenceBase Initializes a new SequenceBase object (sets the id).
Protected methodSequenceBase(SequenceBase) Copy constructor.

Properties
 NameDescription
Public propertyChildrenBase Enumerates all child sequence computation objects
Public propertyExecutionState the state of executing this sequence base (a sequence base comprises sequences, sequence computations, sequence expressions)
Public propertyStatic memberFireDebugEvents 
Public propertyId returns the sequence /expresion id - every sequence /expression is assigned a unique id that is used in xgrs code generation and in sequence rendering for copies a new id is generated, too, this does not cause problems as code is only generated once per defined sequence
Public propertyPrecedence 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!
Public propertySymbol A string symbol representing this sequence /expression kind.

Methods
 NameDescription
Public methodCheck Checks the sequence /expression for errors utilizing the given checking environment reports them by exception

Protected methodCheckNodeTypeIsKnown 
Public methodContains Returns whether the potentialChild is contained in this sequence (base). True if potentialChild is the same as this sequence (base) (so reflexive relation).

Public methodGetCurrentlyExecutedSequenceBase Returns the innermost sequence base beneath this as root which gets currently executed (for sequences on call stack this is the call). A path in the sequence tree gets executed, the innermost is the important one.
Protected methodStatic memberGetEdgeType 
Public methodStatic memberGetFunction 
Public methodGetLocalVariables(DictionarySequenceVariable, SetValueType, ListSequenceExpressionConstructor, SequenceBase) Walks the sequence tree from this on to the given target sequence base (inclusive), collecting all variables found on the way into the variables dictionary, and all container and object type constructors used into the constructors array.

Public methodSetNeedForProfiling sets for the very node the profiling flag (does not recurse)
Public methodSetNeedForProfilingRecursive sets for the node and all children, i.e. the entire tree the profiling flag
Public methodType Returns the type of the sequence /expression (for sequences always "boolean")

Fields
 NameDescription
Protected fieldid stores the sequence /expression unique id
Protected fieldStatic memberidSource the static member used to assign the unique ids to the sequence /expression instances
Public fieldStatic membernoDebugEvents Iff true, no debug (mostly action) events are fired during sequence and rule execution (so debugging is not possible).
Public fieldStatic membernoEvents Iff true, in addition to debug events, no attribute change events are fired during sequence and rule execution (thus also transaction/backtracking breaks, as well as recording/replaying).
Public fieldStatic memberrandomGenerator A common random number generator for all sequence /expression objects. It uses a time-dependent seed.
