이름 설명
AttachWhereClauseVisitor AttachWhereClauseVisitor traverses the WHERE clause and attachs predicates into nodes and edges of constructed graph.
BindTableVisitor BindTableVisitor traverses a boolean expression and returns exposed name of a table if all columns involved in the expression are from that table, otherwise it returns an empty string.
CandidateJoinUnit A 1-height tree is a node with one or more outgoing edges. A 1-height tree is translated to a table alias, plus one or more Transpose() functions. One Transpose() function populates instances of one edge.
ConnectedComponent
ConvertToModificationStatementVisitor The visitor that converts SQL modification statements (i.e., INSERT and DELETE) to graph modification statements: INSERT NODE, DELETE NODE, INSERT EDGE and DELETE EDGE
DeployScriptTemplate
DeployScriptTemplateBase
DeployScriptTemplateBase.ToStringInstanceHelper Utility class to produce culture-oriented representation of an object as a string.
EdgeInfo
EdgeViewBfsRegister
EdgeViewBfsScriptTemplateBase
EdgeViewBfsScriptTemplateBase.ToStringInstanceHelper Utility class to produce culture-oriented representation of an object as a string.

EdgeViewGraphViewCodeTemplate
EdgeViewGraphViewCodeTemplateBase
EdgeViewGraphViewCodeTemplateBase.ToStringInstanceHelper Utility class to produce culture-oriented representation of an object as a string.

GraphViewDefinedFunctionRegister
GraphViewParser The parser first extracts all tokens containing MATCH clauses, then replace them with multiline comment. The original parser will parse remaining tokens and return a syntax tree. Finally, MATCH clauses are inserted into appropriate QueryBlock by traversing the syntax tree.
GraphViewParser.AnnotationToken
GraphViewParser.CollectionObject
GraphViewParser.LexicalAnalyzer
GraphViewParser.NormalObject
GraphViewParser.StringObject
InsertEdgeSelectVisitor
MatchClauseVisitor The visitor that puts the MATCH clause back to the SELECT query block
MatchComponent The Component in the joining process
MatchEdge
MatchGraph
MatchNode
MatchPath
MetaFunctionRegister
MetaGraphViewCodeTemplate
MetaGraphViewCodeTemplateBase
MetaGraphViewCodeTemplateBase.ToStringInstanceHelper Utility class to produce culture-oriented representation of an object as a string.
NodeColumns
NodeTableGraphViewCodeTemplate
NodeTableGraphViewCodeTemplateBase
NodeTableGraphViewCodeTemplateBase.ToStringInstanceHelper Utility class to produce culture-oriented representation of an object as a string.
NodeTableRegister
OneHeightTree A 1-height tree is a node with one or more outgoing edges. A 1-height tree is translated to a table alias, plus one or more Transpose() functions. One Transpose() function populates instances of one edge.
RemoveSchemanameInIdentifersVisitor When a table in the FROM clause is not given an alias, this table will be assigned its table name as its alias, and all references with schema name corresponding to this table should be replaced with the assigned alias by removing the schema name since it is invalid to have a schema identifier before an alias.
ReplaceEdgeReferenceVisitor When an edge in the MATCH clause is not given an alias, this edge can still be referenced by the edge column name. During translation, an edge without an explicit alias will be assigned a default alias, and as a result, the edge column name must be replaced by the assigned alias.
TranslateDataModificationVisitor
TranslateMatchClauseVisitor Translate match clause and add it to the from clause. Check validity -> Divide the graph into connected sub-graph -> Retrive the estimation -> Use DP-like algorithem to get the component -> add the component(s) into from clause
TranslateMatchClauseVisitor.UnionFind Uses the union-Find algorithm to decompose the graph pattern into fully-connected components
