• public static final GenericsType[] EMPTY_GENERICS_ARRAY

• public static final String JAVA_LANG_OBJECT

Method Detail

• public static Map<String, ClassNode> addMethodGenerics(MethodNode current, Map<String, ClassNode> oldSpec)

• @Deprecated public static GenericsType[] alignGenericTypes(GenericsType[] redirectGenericTypes, GenericsType[] parameterizedTypes, GenericsType[] alignmentTarget)

  Given a parameterized type and a generic type information, aligns actual type parameters. For example, if a class uses generic type

  <T,U,V>

  (redirectGenericTypes), is used with actual type parameters

  <java.lang.String, U,V>

  , then a class or interface using generic types

  <T,V>

  will be aligned to

  <java.lang.String,V>

  deprecated:

  You shouldn't call this method because it is inherently unreliable

  Parameters:

  redirectGenericTypes - the type arguments or the redirect class node

  parameterizedTypes - the actual type arguments used on this class node

  alignmentTarget - the generic type arguments to which we want to align to

  Returns:

  aligned type arguments

• public static GenericsType[] applyGenericsContextToPlaceHolders(Map<String, ClassNode> genericsSpec, GenericsType[] oldPlaceHolders)

  transforms generics types from an old context to a new context using the given spec. This method assumes all generics types will be placeholders. WARNING: The resulting generics types may or may not be placeholders after the transformation.

  Parameters:

  genericsSpec - the generics context information spec

  oldPlaceHolders - the old placeholders

  Returns:

  the new generics types

• public static GenericsType buildWildcardType(ClassNode... types)

  Generates a wildcard generic type in order to be used for checks against class nodes. See GenericsType#isCompatibleWith(org.codehaus.groovy.ast.ClassNode).

  Parameters:

  types - the type to be used as the wildcard upper bound

  Returns:

  a wildcard generics type

• public static Map<String, GenericsType> extractPlaceholders(ClassNode cn)

• public static void extractPlaceholders(ClassNode node, Map<String, GenericsType> map)

  For a given classnode, fills in the supplied map with the parameterized types it defines.

  Parameters:

  node - the class node to check

  map - the generics type information collector

• public static void extractSuperClassGenerics(ClassNode type, ClassNode target, Map<String, ClassNode> spec)

• public static ClassNode findParameterizedType(ClassNode genericsClass, ClassNode actualType)

  Get the parameterized type by search the whole class hierarchy according to generics class and actual receiver. findParameterizedTypeFromCache(ClassNode, ClassNode) is strongly recommended for better performance.

  Parameters:

  genericsClass - the generics class

  actualType - the actual type

  Returns:

  the parameterized type

• public static ClassNode findParameterizedTypeFromCache(ClassNode genericsClass, ClassNode actualType)

  Try to get the parameterized type from the cache. If no cached item found, cache and return the result of findParameterizedType(ClassNode, ClassNode)

• @Deprecated public static ClassNode parameterizeInterfaceGenerics(ClassNode hint, ClassNode target)

  Interface class nodes retrieved from ClassNode.getInterfaces or ClassNode.getAllInterfaces are returned with generic type arguments. This method allows returning a parameterized interface given the parameterized class node which implements this interface.

  deprecated:

  Use #parameterizeType instead

  Parameters:

  hint - the class node where generics types are parameterized

  target - the interface we want to parameterize generics types

  Returns:

  a parameterized interface class node

• public static ClassNode parameterizeType(ClassNode hint, ClassNode target)

  Interface class nodes retrieved from ClassNode.getInterfaces or ClassNode.getAllInterfaces are returned with generic type arguments. This method allows returning a parameterized interface given the parameterized class node which implements this interface.

  Parameters:

  hint - the class node where generics types are parameterized

  target - the interface we want to parameterize generics types

  Returns:

  a parameterized interface class node
