Syntax

Copy

public abstract class SequenceBase

The SequenceBase type exposes the following members.

Constructors

	Name	Description
	SequenceBase	Initializes a new SequenceBase object (sets the id).
	SequenceBase(SequenceBase)	Copy constructor.

Properties

	Name	Description
	ChildrenBase	Enumerates all child sequence computation objects
	ExecutionState	the state of executing this sequence base (a sequence base comprises sequences, sequence computations, sequence expressions)
	FireDebugEvents
	Id	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
	Precedence	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!
	Symbol	A string symbol representing this sequence /expression kind.

Methods

	Name	Description
	Check	Checks the sequence /expression for errors utilizing the given checking environment reports them by exception
	CheckBaseObjectTypeIsKnown
	CheckEdgeTypeIsKnown
	CheckGraphElementTypeIsKnown
	CheckNodeTypeIsKnown
	Contains	Returns whether the potentialChild is contained in this sequence (base). True if potentialChild is the same as this sequence (base) (so reflexive relation).

	GetAction
	GetCurrentlyExecutedSequenceBase	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.
	GetEdgeType
	GetFunction
	GetLocalVariables(SequenceExpression, DictionarySequenceVariable, SetValueType, ListSequenceExpressionConstructor)
	GetLocalVariables(SequenceFilterCall, DictionarySequenceVariable, SetValueType, ListSequenceExpressionConstructor)
	GetLocalVariables(ListSequenceFilterCallBase, DictionarySequenceVariable, SetValueType, ListSequenceExpressionConstructor)
	GetLocalVariables(SequenceFilterCallLambdaExpression, DictionarySequenceVariable, SetValueType, ListSequenceExpressionConstructor)
	GetLocalVariables(SequenceVariable, DictionarySequenceVariable, SetValueType, ListSequenceExpressionConstructor)
	GetLocalVariables(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.
	GetNodeType
	GetProcedure
	GetSequence
	GetTypeString
	HasSequenceType
	InitializeArgumentExpressionsAndArguments
	InitializeReturnVariables
	RemoveVariablesFallingOutOfScope
	SetNeedForProfiling	sets for the very node the profiling flag (does not recurse)
	SetNeedForProfilingRecursive	sets for the node and all children, i.e. the entire tree the profiling flag
	Type	Returns the type of the sequence /expression (for sequences always "boolean")

Fields

	Name	Description
	id	stores the sequence /expression unique id
	idSource	the static member used to assign the unique ids to the sequence /expression instances
	noDebugEvents	Iff true, no debug (mostly action) events are fired during sequence and rule execution (so debugging is not possible).
	noEvents	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).
	randomGenerator	A common random number generator for all sequence /expression objects. It uses a time-dependent seed.
