demandConstructor
Returns the(i+1)
'th constructor of the given type declaration, in textual order. The constructor that appears first has the index 0, the second one the index 1, and so on.- Parameters:
td
- The type declaration to search in. Note that only classes and enums have constructors.index
- The index of the desired constructor.- Returns:
- The desired ConstructorDeclaration if it was found, else an exception is thrown.

findType
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
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 declaration defines class D and class D contains an internal class named E then the qualifiedName that can be resolved are "D", and "D.E". -
