Method Detail

getTypeDeclarationByName

public static com.github.javaparser.ast.body.TypeDeclaration<?> getTypeDeclarationByName(com.github.javaparser.ast.CompilationUnit root,
                                                                                         String name)

Given the compilation unit node for a source file, returns the top level type definition with the given name.

Parameters:

root - compilation unit to search

name - name of a top level type declaration in root

Returns:

a top level type declaration in root named name

getFullyQualifiedName

public static String getFullyQualifiedName(com.github.javaparser.ast.body.TypeDeclaration<?> type,
                                           com.github.javaparser.ast.CompilationUnit compilationUnit)

Returns the fully qualified name of a type appearing in a given compilation unit.

Parameters:

type - a type declaration

compilationUnit - the compilation unit containing type

Returns:

the fully qualified name of type if compilationUnit contains a package declaration, or just the name of type otherwise

clearAnnotations

public static void clearAnnotations(com.github.javaparser.ast.Node node)

Side-effects node by removing all annotations from anywhere inside its subtree.

Parameters:

node - a JavaParser Node

concatenateAddedStringLiterals

public static void concatenateAddedStringLiterals(com.github.javaparser.ast.Node node)

Side-effects node by combining any added String literals in node's subtree into their concatenation. For example, the expression "a" + "b" becomes "ab". This occurs even if, when reading from left to right, the two string literals are not added directly. For example, the expression 1 + "a" + "b" parses as (1 + "a") + "b"}, but it is transformed into 1 + "ab".

This is the same transformation performed by javac automatically. Javac seems to ignore string literals surrounded in parentheses, so this method does as well.

Parameters:

node - a JavaParser Node
