|
Here are the build notes for the Eclipse JDT/Core plug-in project
org.eclipse.jdt.core,
describing bug resolution and substantial changes in the R3_4_maintenance branch.
For more information on 3.4 planning, please refer to JDT/Core release plan,
the next milestone plan,
the overall official plan,
or the build schedule.
This present document covers all changes since Release 3.3 (also see a summary of API changes).
Maintenance of previous releases of JDT/Core is performed in parallel branches: R3.3.x, R3.2.x, R3.1.x, R3.0.x, R2.1.x, R2.0.x, R1.0.x. |
.zip and .jar can now be put on the classpath as well.
See bug 182360 for details.
This flag is defined in CodeFormatter and named 'F_INCLUDE_COMMENTS'.
Clients will have to combine it with existing CodeFormatter.K_COMPILATION_UNIT
or CodeFormatter.UNKNOWN kinds to see the fix for this bug activated...
org.eclipse.jdt.core.formatter.CodeFormatter:
/**
* Flag used to include the comments during the formatting of the code
* snippet.
*
* This flag can only be combined with following kinds:
* . {@link #K_COMPILATION_UNIT}
* . {@link #K_UNKNOWN}
*
* Note also that it has an effect only when the option
* {@link DefaultCodeFormatterConstants
* #FORMATTER_COMMENT_FORMAT_JAVADOC_COMMENT}
* is set to {@link DefaultCodeFormatterConstants#TRUE} while calling
* {@link #format(int, String, int, int, int, String)} or
* {@link #format(int, String, IRegion[], int, String)} methods
*
* For example, with the Eclipse default formatter options, the formatting of
* the following code snippet using {@link #K_COMPILATION_UNIT}:
*
* public class X {
* /**
* * This is just a simple example to show that comments will be formatted while processing a compilation unit only if the constant flag F_INCLUDE_COMMENT flag is set.
* * @param str The input string */
* void foo(String str){}}
*
* will produce the following output:
*
* public class X {
* /**
* * This is just a simple example to show that comments will be formatted while processing a compilation unit only if the constant flag F_INCLUDE_COMMENT flag is set.
* *
* * @param str The input string
* */
* void foo(String str){
* }
* }
*
* Adding this flavor to the kind given while formatting the same source
* (e.g. {@link #K_COMPILATION_UNIT} | {@link #F_INCLUDE_COMMENTS})
* will produce the following output instead:
*
* public class X {
* /**
* * This is just a simple example to show that comments will be formatted
* * while processing a compilation unit only if the constant flag
* * F_INCLUDE_COMMENT flag is set.
* *
* * @param str
* * The input string
* */
* void foo(String str){
* }
* }
*
* Note: Although we're convinced that the formatter should
* always include the comments while processing a
* {@link #K_COMPILATION_UNIT kind of compilation unit}, we
* have decided to add a specific flag to fix this formatter incorrect behavior.
* This will prevent all existing clients using the {@link #K_COMPILATION_UNIT}
* kind to be broken while formatting.
*
* @since 3.4
*/
public static final int F_INCLUDE_COMMENTS = 0x1000;
Note that CodeFormatter.UNKNOWN and CodeFormatter.K_COMPILATION_UNIT
specification will be updated to include this new possible combination:
/**
* Unknown kind
*
* Note that since 3.4, the {@link #F_INCLUDE_COMMENTS} flag can be added
* to this constant in order to get the comments formatted if a
* compilation unit is processed.
*/
public static final int K_UNKNOWN = 0x00;
/**
* Kind used to format a compilation unit
*
* Note that using this constant, the javadoc comments are only indented while
* processing the compilation unit.
*
* Since 3.4, if the corresponding comment option is set to
* true then it is also possible to format the comments on the fly
* by adding the {@link #F_INCLUDE_COMMENTS} flag to this kind of format.

JavaCore.COMPILER_PB_MISSING_JAVADOC_TAG_DESCRIPTION_ALL_TAGS introduced in 3.4M3 has been renamed to
COMPILER_PB_MISSING_JAVADOC_TAG_DESCRIPTION_ALL_STANDARD_TAGS.Class-Path clause of jar files
manifests to complete the classpath. For jar files that are specified on a
-classpath option, the compiler follows Class-Path
clauses recursively and appends each referenced jar file to the end of the
classpath, provided it is not on the classpath yet. See bug

ReferenceMatch API class:
/**
* An abstract Java search match that represents a reference.

* This class is not intended to be subclassed by clients.
*
* @since 3.4
*/
public abstract class ReferenceMatch extends SearchMatch {
...
/**
* Returns the local element of this search match, or null if none.
* A local element is the inner most element that contains the reference and that is not
* reachable by navigating from the root of the {@link IJavaModel} using
* {@link IParent#getChildren()}.
*
* Known element types for local elements are {@link IJavaElement#ANNOTATION},
* {@link IJavaElement#LOCAL_VARIABLE} and {@link IJavaElement#TYPE_PARAMETER}.
* However clients should not assume that this set of element types is closed as
* other types of elements may be returned in the future, e.g. if new types
* of elements are added in the Java model. Clients can only assume that the
* {@link IJavaElement#getParent() parent} chain of this local element eventually leads
* to the element from {@link #getElement()}.
*
* The local element being an {@link IAnnotation} is the most usal case. For example,
*
* . searching for the references to the method Annot.clazz() in
*
* public class Test {
* void method() {
* @Annot(clazz=Test.class) int x;
* }
* }
*
* will return one {@link MethodReferenceMatch} match whose local element
* is the {@link IAnnotation} 'Annot'.
*
* . searching for the references to the type Deprecated in
*
* public class Test {
* @Deprecated void method() {}
* }
*
* will return one {@link TypeReferenceMatch} match whose local element
* is the {@link IAnnotation} 'Deprecated'.
*
* . searching for the references to the field CONST in
*
* @Num(number= Num.CONST)
* @interface Num {
* public static final int CONST= 42;
* int number();
* }
*
* will return one {@link FieldReferenceMatch} match whose local element
* is the {@link IAnnotation} 'Num'.
*
* A local element may also be a {@link ILocalVariable} whose type is the referenced type. For example,
*
* . searching for the references to the type Test in
*
* public class Test {
* void foo() {
* Test local;
* }
* }
*
* will return one {@link TypeReferenceMatch} match whose local element
* is the {@link ILocalVariable} 'local'.
*
* Or a local element may be an {@link ITypeParameter} that extends the referenced type. For example,
*
* . searching for the references to the type Test in
*
* public class X<T extends Test> {
* }
*
* will return one {@link TypeReferenceMatch} match whose local element
* is the {@link ITypeParameter} 'T'.
*
* @return the local element of this search match, or null if none.

*
* Examples:
* . 'HM' type string pattern will match 'HashMap' and 'HtmlMapper' types,

* . 'HMap' type string pattern will match 'HashMap' type but not 'HtmlMapper'.
*
* This Camel Case match rule does not allow prefix match but accept insensitive
* case. For instance, 'HashMap' or 'HASHMAP' patterns using this Camel Case
* rule will match both 'HashMap' but not 'HashMapEntry'.
*
* This rule still can be combined to prefix match to accept prefix matches
* ('HashMap' pattern matching 'HashMapEntry' name). It can also be combined
* to case sensitive match to reject case insensitive matches ('HAMA' pattern
* will not match 'HashMap' name).
*
* If {@link #R_PATTERN_MATCH} rule is also combined, then the real used
* match rule will depend on whether string pattern contains specific pattern
* characters (e.g. '*' or '?') or not. If it does, then only Pattern match rule will
* be used, otherwise only Camel Case match will be used.
* For example, with 'NPE' string pattern, search will only use
* Camel Case match rule, but with 'N*P*E*' string pattern, it will
