findType
public static Optional<com.github.javaparser.ast.body.TypeDeclaration<?>> findType(com.github.javaparser.ast.CompilationUnit cu, String qualifiedName)
Looks among the type declared in the Compilation Unit for one having the specified name. The name can be qualified with respect to the compilation unit. For example, if the compilation unit is in package a.b; and it contains two top level classes named C and D, with class E being defined inside D then the qualifiedName that can be resolved are "C", "D", and "D.E".
-
findType
public static Optional<com.github.javaparser.ast.body.TypeDeclaration<?>> findType(com.github.javaparser.ast.body.TypeDeclaration<?> td, String qualifiedName)
Looks among the type declared in the TypeDeclaration for one having the specified name. The name can be qualified with respect to the TypeDeclaration. For example, if the class declarationd defines class D and class D contains an internal class named E then the qualifiedName that can be resolved are "D", and "D.E".
