IconMemberDescription
PatternEdge(Boolean, Int32, EdgeType, String, String, String, array<GrGenType>[]()[][], array<Boolean>[]()[][], Single, Int32, Boolean, StorageAccess, StorageAccessIndex, IndexAccess, NameLookup, UniqueLookup, PatternElement, Boolean, Expression)
Instantiates a new PatternEdge object

PatternEdge(PatternEdge, PatternGraphEmbedding, PatternGraph, String)
Instantiates a new PatternEdge object as a copy from an original edge, used for subpattern inlining.

PatternEdge(PatternEdge, String)
Instantiates a new PatternEdge object as a copy from an original edge, used for independent inlining.

AllowedTypes
An array of allowed types for this pattern element. If it is null, all subtypes of the type specified by typeID (including itself) are allowed for this pattern element.
(Inherited from PatternElement.)
annotations
The annotations of the pattern element
(Inherited from PatternElement.)
Annotations
The annotations of the pattern element
(Inherited from PatternElement.)
AssignmentSource
If not null this pattern element is to be bound by assigning the given assignmentSource to the pattern element. This is needed to fill the pattern parameters of a pattern embedding which was inlined.
(Inherited from PatternElement.)
Cost
Default cost/priority from frontend, user priority if given.
(Inherited from PatternElement.)
defToBeYieldedTo
Iff true the element is only defined in its PointOfDefinition pattern, it gets matched in another, nested or called pattern which yields it to the containing pattern.
(Inherited from PatternElement.)
DefToBeYieldedTo
Iff true the element is only defined in its PointOfDefinition pattern, it gets matched in another, nested or called pattern which yields it to the containing pattern.
(Inherited from PatternElement.)
ElementBeforeCasting
If not null this pattern element is to be bound by casting the given ElementBeforeCasting to the pattern element type or causing matching to fail.
(Inherited from PatternElement.)
fixedDirection
Indicates, whether this pattern edge should be matched with a fixed direction or not.

GetPatternElementThisElementDependsOnOutsideOfGraphConnectedness()()()()
Returns the pattern element we depend on, for a storage lookup, or an indexed storage lookup, or an index lookup
(Inherited from PatternElement.)
IndexAccess
If not null this pattern element is to be determined by an index lookup, with details specified by the concrete index access type contained in this field.
(Inherited from PatternElement.)
initialization
The initialization expression for the element if some was defined, otherwise null.
(Inherited from PatternElement.)
Initialization
The initialization expression for the element if some was defined, otherwise null.
(Inherited from PatternElement.)
IsAllowedType
An array containing a bool for each node/edge type (order defined by the TypeIDs) which is true iff the corresponding type is allowed for this pattern element. It should be null if allowedTypes is null or empty or has only one element.
(Inherited from PatternElement.)
MaybeNull
Tells whether this pattern element may be null. May only be true if pattern element is handed in as rule parameter.
(Inherited from PatternElement.)
name
The name of the pattern element.
(Inherited from PatternElement.)
Name
The name of the pattern element.
(Inherited from PatternElement.)
NameLookup
If not null this pattern element is to be determined by a name map lookup
(Inherited from PatternElement.)
originalEdge
Links to the original pattern edge in case this edge was inlined, otherwise null; the point of definition of the original edge references the original containing pattern

originalElement
Links to the original pattern element in case this element was inlined, otherwise null; the point of definition of the original element references the original containing pattern
(Inherited from PatternElement.)
OriginalIndependentElement
Links to the original pattern element in case this element stems from inlining an independent (those elements exist only in search planning, they are not contained in any pattern).
(Inherited from PatternElement.)
originalSubpatternEmbedding
Links to the original subpattern embedding which was inlined in case this element was inlined, otherwise null.
(Inherited from PatternElement.)
ParameterIndex
Specifies to which rule parameter this pattern element corresponds. Only valid if pattern element is handed in as rule parameter.
(Inherited from PatternElement.)
pointOfDefinition
The pattern where this element gets matched (null if rule parameter).
(Inherited from PatternElement.)
PointOfDefinition
The pattern where this element gets matched (null if rule parameter).
(Inherited from PatternElement.)
PresetBecauseOfIndependentInlining
This element was declared in an independent pattern, but is now to be matched as preset, because it was inlinded in the containing pattern to speed up matching
(Inherited from PatternElement.)
Storage
If not null this pattern element is to be bound by iterating the given storage (which may mean trying the single value if it is elementary).
(Inherited from PatternElement.)
StorageIndex
If not null this pattern element is to be determined by a storage indexed lookup, with the accessor given here applied as index into the storage given in the Storage field.
(Inherited from PatternElement.)
TempPlanMapping
plan graph node corresponding to this pattern element, used in plan graph generation, just hacked into this place
(Inherited from PatternElement.)
ToString()()()()
Converts this instance into a string representation.
(Overrides PatternElement.ToString()()()().)
type
The GrGen type of the pattern edge

Type
The GrGen type of the pattern edge.

TypeID
The type ID of the pattern element.
(Inherited from PatternElement.)
typeName
The name of the type interface of the pattern element.
(Inherited from PatternElement.)
UniqueLookup
If not null this pattern element is to be determined by a unique index lookup
(Inherited from PatternElement.)
unprefixedName
Pure name of the pattern element as specified in the .grg file without any prefixes.
(Inherited from PatternElement.)
UnprefixedName
The pure name of the pattern element as specified in the .grg without any prefixes.
(Inherited from PatternElement.)
visited
visited flag used to compute pattern connectedness for inlining, just hacked into this place
(Inherited from PatternElement.)
