Method Details

generateVariableName

public static String generateVariableName(String baseName,
 org.openrewrite.Cursor scope,
 VariableNameUtils.GenerationStrategy strategy)

Generates a variable name without namespace conflicts in the scope of a cursor. A JavaSourceFile must be available in the Cursor path to account for all names available in the cursor scope.

Parameters:

baseName - baseName for the variable.

scope - The cursor position of a JavaVisitor, TreeVisitor.getCursor().

strategy - VariableNameUtils.GenerationStrategy to use if a name already exists with the baseName.

Returns:

either the baseName if a namespace conflict does not exist or a name generated with the provided strategy.

normalizeName

public static String normalizeName(String name)

Replace accent and diacritics with normalized characters.

Parameters:

name - variable name to normalize.

Returns:

normalized name.

findNamesInScope

public static Set<String> findNamesInScope(org.openrewrite.Cursor scope)

Find the names of variables that already exist in the scope of a cursor. A JavaSourceFile must be available in the Cursor path to account for all names available in the cursor scope.

Parameters:

scope - The cursor position of a JavaVisitor, TreeVisitor.getCursor().

Returns:

Variable names available in the name scope of the cursor.

findInheritedNames

public static Set<String> findInheritedNames(J.ClassDeclaration classDeclaration)

Collects class field names inherited from super classes. Note: Does not currently account for JavaType.Unknown.
