The Java model is the set of classes that model the objects associated with creating, editing, and building a Java program.

           Description

Interface Summary
IAccessRule	Describes an access rule to source and class files on a classpath entry.
IAnnotatable	Common protocol for Java elements that can be annotated.
IAnnotation	Represents an annotation on a package declaration, a type, a method, a field or a local variable in a compilation unit or a class file.
IBuffer	A buffer contains the text contents of a resource.
IBuffer.ITextEditCapability	Implementors of IBuffer can additionally implement IBuffer.ITextEditCapability.
IBufferChangedListener	A listener, which gets notified when the contents of a specific buffer have changed, or when the buffer is closed.
IBufferFactory	Deprecated. Use WorkingCopyOwner instead
IClassFile	Represents an entire binary type (single .class file).
IClasspathAttribute	A classpath attribute defines a name/value pair that can be persisted with a classpath entry.
IClasspathContainer	Interface of a classpath container.
IClasspathEntry	An entry on a Java project classpath identifying one or more package fragment roots.
ICodeAssist	Common protocol for Java elements that support source code assist and code resolve.
ICodeCompletionRequestor	Deprecated. Use CompletionRequestor instead.
ICodeFormatter	Deprecated. Use CodeFormatter instead (note: options have changed)
ICompilationUnit	Represents an entire Java compilation unit (source file with one of the Java-like extensions).
ICompletionRequestor	Deprecated. Use CompletionRequestor instead.
ICorrectionRequestor	A callback interface for receiving java problem correction.
IElementChangedListener	An element changed listener receives notification of changes to Java elements maintained by the Java model.
IField	Represents a field declared in a type.
IImportContainer	Represents an import container is a child of a Java compilation unit that contains all (and only) the import declarations.
IImportDeclaration	Represents an import declaration in Java compilation unit.
IInitializer	Represents a stand-alone instance or class (static) initializer in a type.
IJarEntryResource	A jar entry corresponding to a non-Java resource in an archive IPackageFragment or IPackageFragmentRoot.
IJavaElement	Common protocol for all elements provided by the Java model.
IJavaElementDelta	A Java element delta describes changes in Java element between two discrete points in time.
IJavaModel	Represent the root Java element corresponding to the workspace.
IJavaModelMarker	Markers used by the Java model.
IJavaModelStatus	Represents the outcome of an Java model operation.
IJavaModelStatusConstants	Status codes used with Java model status objects.
IJavaProject	A Java project represents a view of a project resource in terms of Java elements such as package fragments, types, methods and fields.
ILocalVariable	Represents a local variable declared in a method or an initializer.
IMember	Common protocol for Java elements that can be members of types.
IMemberValuePair	Represents a member-value pair of an annotation.
IMethod	Represents a method (or constructor) declared in a type.
IOpenable	Common protocol for Java elements that must be opened before they can be navigated or modified.
IPackageDeclaration	Represents a package declaration in Java compilation unit.
IPackageFragment	A package fragment is a portion of the workspace corresponding to an entire package, or to a portion thereof.
IPackageFragmentRoot	A package fragment root contains a set of package fragments.
IParent	Common protocol for Java elements that contain other Java elements.
IProblemRequestor	A callback interface for receiving java problem as they are discovered by some Java operation.
IRegion	A Java model region describes a hierarchical set of elements.
ISourceManipulation	Common protocol for Java elements that support source code manipulations such as copy, move, rename, and delete.
ISourceRange	A source range defines an element's source coordinates relative to its source buffer.
ISourceReference	Common protocol for Java elements that have associated source code.
IType	Represents either a source type in a compilation unit (either a top-level type, a member type, a local type or an anonymous type) or a binary type in a class file.
ITypeHierarchy	A type hierarchy provides navigations between a type and its resolved supertypes and subtypes for a specific type or for all types within a region.
ITypeHierarchyChangedListener	A listener which gets notified when a particular type hierarchy object changes.
ITypeParameter	Represents a type parameter defined by a type or a method in a compilation unit or a class file.
ITypeRoot	Represents an entire Java type root (either an ICompilationUnit or an IClassFile).
IWorkingCopy	Deprecated. Use ICompilationUnit instead

 

Class Summary
BindingKey	Utility class to decode or create a binding key.
BufferChangedEvent	A buffer changed event describes how a buffer has changed.
CheckDebugAttributes	An Ant task to find out if a class file or a jar contains debug attributes.
ClasspathContainerInitializer	Abstract base implementation of all classpath container initializer.
ClasspathVariableInitializer	Abstract base implementation of all classpath variable initializers.
CompletionContext	Completion context.
CompletionFlags	Utility class for decoding additional flags in completion proposal.
CompletionProposal	Completion proposal.
CompletionRequestor	Abstract base class for a completion requestor which is passed completion proposals as they are generated in response to a code assist request.
CompletionRequestorAdapter	Deprecated. Subclass CompletionRequestor instead.
CorrectionEngine	This class is the entry point for source corrections.
ElementChangedEvent	An element changed event describes a change to the structure or contents of a tree of Java elements.
Flags	Utility class for decoding modifier flags in Java elements.
JavaConventions	Provides methods for checking Java-specific conventions such as name syntax.
JavaCore	The plug-in runtime class for the Java model plug-in containing the core (UI-free) support for Java projects.
JDTCompilerAdapter	Ant 1.5 compiler adapter for the Eclipse Java compiler.
NamingConventions	Provides methods for computing Java-specific names.
Signature	Provides methods for encoding and decoding type and method signature strings.
ToolFactory	Factory for creating various compiler tools, such as scanners, parsers and compilers.
WorkingCopyOwner	The owner of an ICompilationUnit handle in working copy mode.

 

Exception Summary
JavaModelException	A checked exception representing a failure in the Java model.

 

Package org.eclipse.jdt.core Description

The Java model is the set of classes that model the objects associated with creating, editing, and building a Java program.

Package Specification

This package contains the Java model classes, which implement Java specific behaviour for resources and further decompose Java resources into model elements.

Note that a lot of Java model operations require a Java project's classpath resolution. For example IJavaProject#getResolvedClasspath(boolean) or JavaCore#setClasspathContainer() will require to resolve the classpath of one or more projects. Client should be aware that this resolution may require to take project modification rule (see IResourceRuleFactory#modifyRule(IResource)).
