TypeName.get() would throw on error types, masking other errors in an annotation processing round. This is fixed with a test to prevent future regressions!TYPE_USE annotations on each enclosing ClassName.TypeName.get(TypeElement). There was a problem getting an element's kind when building from source ABIs.$Z as an optional newline (zero-width space) if a line may exceed 100 chars.CodeBlock.join() and CodeBlock.joining() let you join codeblocks by delimiters.CodeBlock.Builder.isEmpty().addStatement(CodeBlock) overloads for CodeBlock and MethodSpec.$.ClassName.get().MethodSpec.Builder.addNamedCode() and TypeSpec.anonymousClassBuilder(CodeBlock).New: Basic support for line wrapping. Use $W to insert a Wrappable Whitespace character. It'll emit either a single space or a newline with appropriate indentation.
New: Named arguments in CodeBlock. These are intended to make larger code snippets easier to read:
Map<String, Object> map = new LinkedHashMap<>();
map.put("count", 3);
map.put("greeting", "Hello, ");
map.put("system", System.class);
String template = ""
+ "for (int i = 0; i < $count:L; i++) {\n"
+ " $system:T.out.println($greeting:S + list.get(i));\n"
+ "}\n";
CodeBlock.Builder builder = CodeBlock.builder();
builder.addNamed(template, map);
New: addJavadoc(CodeBlock) overloads for TypeSpec, MethodSpec, and FieldSpec.
New: MethodSpec.addComment() makes it easy to add a // single-line comment.
New: ClassName.getReflectionName() returns a string like java.util.Map$Entry.
Fix: Always write UTF-8. Previously JavaPoet would use the system default charset which was potentially inconsistent across environments.
Fix: Permit (constant) fields to be defined in annotation types.
Outer<String>.Inner.TypeName.isBoxedPrimitive().CodeBlock.of(), a handy factory method for building code blocks.TypeSpec factory methods that take a ClassName.TypeName.annotated() adds an annotation to a type.TypeVariableName.withBounds() adds bounds to a type variable.TypeSpec.Builder.addInitializerBlock() adds an instance initializer.TypeSpec.Kind enum public. This can be used to check if a TypeSpec is a class, interface, enum, or annotation.private on annotation members.MethodSpec.Builder.ErrorType like a regular DeclaredType in TypeName.get(). This should make it easier to write annotation processors.TypeName instances are only equal if their annotations are equal.import static! See JavaFile.Builder.addStaticImport() variants.NameAllocator.newName(String) for creating a one-off name without a tag.TypeVariableName is part of ParameterizedTypeName.add("$1S", "a", "b").AnnotationSpec.get(Annotation).TypeName.annotated() can attach annotations like @Nullable directly to types. This works for both top-level types and type parameters as in List<@Nullable String>.equals() and hashCode() on AnnotationSpec, CodeBlock, FieldSpec, JavaFile, MethodSpec, ParameterSpec, TypeName, and TypeSpec.NameAllocator.clone() to refine a NameAllocator for use in an inner scope code block.TypeVariableName gets a self-referential type.NameAllocator API makes it easy to declare non-conflicting names.TypeName.get(TypeMirror).$1T and $2N. Indexes can be used to refer to the same argument multiple times in a single format string.addStaticBlock().MethodSpec.overriding() retains annotations.$T and $N.MethodSpec.varargs(boolean) to generate varags methods.AnnotationSpec.get() and MethodSpec.overriding() to create annotations and methods from the javax.lang.model API.JavaFile.toJavaFileObject().DEFAULT modifier.toBuilder() methods to build upon objects already constructed.@interface annotation types.TypeName.box() and TypeName.unbox() convenience APIs.nextControlFlow() accepts arguments.WildcardTypeName.get(WildcardType) no longer throws a NullPointerException.javapoet. We renamed the it so you can simultaneously use the old JavaWriter API and our new builder-based APIs in one project..java file from top to bottom, you now define members in whatever way is convenient.StringLiteral type which encapsulates the behavior of stringLiteral.emitEnumValue variant which exposes a boolean of whether the current value is the last.java.lang in compressType.setIndent.beginConstructor method is a semantically clearer alternative for constructors.emitEnumValues method emits a list of values followed by semicolon.emitImports now supports Class arguments directly.int-based modifier methods have been removed.setCompressingTypes controls whether types are emitted as fully-qualified or not.stringLiteral now correctly handles escapes and control characters.Set of Modifiers rather than an int.
