Method Detail

locate

public LinkedHashMap<CodeSnipitLocation,CodeSnipitLocation> locate(com.github.javaparser.ast.CompilationUnit existingCode,
                                                                   com.github.javaparser.ast.Node newCode)

Receives two CompilationUnits and determines the location of a package, imports, fields, constructors, methods or inner classes. This method will retain the order of Nodes in both existing and new code. It can therefore happen that not all nodes are ordered according to the NodeComparator if the inserted code was also not ordered like that.

Parameters:

existingCode - CompilationUnit representing the existing class

newCode - CompilationUnit representing the code to be added

Returns:

An LinkedHashMap with as keys a CodeSnipitLocation of code to be added and as value a CodeSnipitLocation where in the existing class the code should be added. The map is ordered on increasing insert locations (map values).

recursiveLocator

protected LinkedHashMap<CodeSnipitLocation,CodeSnipitLocation> recursiveLocator(List<com.github.javaparser.ast.Node> existingNodes,
                                                                                List<com.github.javaparser.ast.Node> insertNodes)

Calculates the insertion locations for the insertNodes within the existingNodes. Recursively handles classes. The order of the insertNodes is retained, unless an earlier existing node was equal to an insert node.

Parameters:

existingNodes - The nodes from the existing class. May not be empty.

insertNodes - The nodes from the class to be inserted. May not be empty.

Returns:

The map of where insertion-code (from) needs to be inserted (to).
