Method Detail

• public static void addDeclaredMethodsFromAllInterfaces(ClassNode cNode, Map<String, MethodNode> methodsMap)

  Adds methods from interfaces and parent interfaces. Existing entries in the methods map take precedence. Methods from interfaces visited early take precedence over later ones.

  Parameters:

  cNode - The ClassNode

  methodsMap - A map of existing methods to alter

• public static void addDeclaredMethodsFromInterfaces(ClassNode cNode, Map<String, MethodNode> methodsMap)

  Adds methods from all interfaces. Existing entries in the methods map take precedence. Methods from interfaces visited early take precedence over later ones.

  Parameters:

  cNode - The ClassNode

  methodsMap - A map of existing methods to alter

• public static ConstructorNode addGeneratedConstructor(ClassNode classNode, int modifiers, Parameter[] parameters, ClassNode[] exceptions, Statement code)

  Add a method that is marked as @Generated.

  ModuleNode.addClass

• public static MethodNode addGeneratedMethod(ClassNode cNode, String name, int modifiers, ClassNode returnType, Parameter[] parameters, ClassNode[] exceptions, Statement code)

  Return an existing method if one exists or else create a new method and mark it as @Generated.

  ClassNode.addMethod

• public static String formatTypeName(ClassNode cNode)

  Formats a type name into a human-readable version. For arrays, appends "[]" to the formatted type name of the component. For unit class nodes, uses the class node name.

  Parameters:

  cNode - the type to format

  Returns:

  a human-readable version of the type name (java.lang.String[] for example)

• public static Map<String, MethodNode> getDeclaredMethodsFromInterfaces(ClassNode cNode)

  Gets methods from all interfaces. Methods from interfaces visited early take precedence over later ones.

  Parameters:

  cNode - The ClassNode

  Returns:

  A map of methods

• public static Map<String, MethodNode> getDeclaredMethodsFromSuper(ClassNode cNode)

  Add methods from the super class.

  Parameters:

  cNode - The ClassNode

  Returns:

  A map of methods

• public static FieldNode getField(ClassNode classNode, String fieldName)

  Searches the class for a field that matches specified name.

• public static FieldNode getField(ClassNode classNode, String fieldName, Predicate<FieldNode> acceptability)

  Searches the class for a field that matches specified name and test.

• public static String getPropNameForAccessor(String accessorName)

  Returns the property name, e.g. age, given an accessor name, e.g. getAge. Returns the original if a valid prefix cannot be removed.

  Parameters:

  accessorName - the accessor name of interest, e.g. getAge

  Returns:

  the property name, e.g. age, or original if not a valid property accessor name

• public static PropertyNode getStaticProperty(ClassNode cNode, String propName)

  Detect whether a static property with the given name is within the class or a super class.

  Parameters:

  cNode - the ClassNode of interest

  propName - the property name

  Returns:

  the static property if found or else null

• public static boolean hasExplicitConstructor(AbstractASTTransformation xform, ClassNode cNode)

  Determine if an explicit (non-generated) constructor is in the class.

  Parameters:

  xform - if non-null, add an error if an explicit constructor is found

  cNode - the type of the containing class

  Returns:

  true if an explicit (non-generated) constructor was found

• public static boolean hasNoArgConstructor(ClassNode cNode)

• public static boolean hasPossibleStaticMethod(ClassNode cNode, String name, Expression arguments, boolean trySpread)

  Returns true if the given method has a possibly matching static method with the given name and arguments. Handles default arguments and optionally spread expressions.

  Parameters:

  cNode - the ClassNode of interest

  name - the name of the method of interest

  arguments - the arguments to match against

  trySpread - whether to try to account for SpreadExpressions within the arguments

  Returns:

  true if a matching method was found.

  Parameters:

  cNode - the ClassNode of interest

  Returns:

  true if the given node is a (non-static) inner class, else false

• public static boolean isSubtype(ClassNode maybeSuperclassOrInterface, ClassNode candidateChild)

• public static boolean isValidAccessorName(String accessorName)

  Detect whether the given accessor name starts with "get", "set" or "is" followed by at least one character.

  Parameters:

  accessorName - the accessor name of interest, e.g. getAge

  Returns:

  true if a valid prefix is found
