Extract edge information from Cypher.

Extract node information from cypher.

Resolves the hints and applies the algorithm for that case. @param route applied the gtop context on a route

Main method to be implemented by the classes that inherit from this class. @param route @return

Intersection of all possible edges described by the gtop and a possible type defined on query language level. @param currentNode @param originalRoute

Intersection of all possible nodes described by the gtop and a possible type defined on query language level. @param originalRoute @param analysingIn

Generates an anonymous node. @return the anonymous node

Canonical routes are a list of all the routes possible due to wild-card expansion. No Gtop expansion is done at this stage. @param input @return

@return the edges

@return the nodes

Get the edges that start or end with node. @param nodeA nodeA to look for @return list of Abstraction Edges

@return the columnName

@return the concatenationPosition

Return destination node types for a given edge. @param analyzedEdge edge to lookup @return list node types that this edge directs to

Follows directed edges.

Get the map of hints for this path where the hints have been converted as List of string instead of a map. @return

@return the id

Finds an Implementation edges by type. @param type @return

@return the edges

@return the implementationLevel

@return the nodes

@return the inputFormat

@return the maximumRange

@return the minimumRange

Return source node types for a given edge. @param analyzedEdge edge to lookup @return set of two nodes for this edge

@return the types

Returns the list of variables found. @return Returns the list of variables found.

Generates all possible paths, using the edge expansions. @param currentAnalysedPosition current position being analysed in the route @param originalR

Adds an expanded edge to the original route. @param currentAnalysedPosition @param expansionPath @param thisIterationRoute @return

Checks if the edge can be expanded. @return true if the edge is expandable, otherwise false

@return the isSource

@return the toLeft

Launches the enumeration process. @param hasEdgeHints true if there are edge hints @param hasNodeHints true if there are node hints @param hasVariabl
