Interface IType

All Superinterfaces:

org.eclipse.core.runtime.IAdaptable, IAnnotatable, IJavaElement, IMember, IParent, ISourceManipulation, ISourceReference

All Known Implementing Classes:

AssistSourceType, BinaryLambdaExpression, BinaryType, LambdaExpression, ResolvedBinaryType, ResolvedLambdaExpression, ResolvedSourceType, SourceType

public interface IType
extends IMember, IAnnotatable

Represents either a source type in a compilation unit (either a top-level type, a member type, a local type, an anonymous type or a lambda expression) or a binary type in a class file. Enumeration classes and annotation types are subkinds of classes and interfaces, respectively.

Note that the element name of an anonymous source type and lambda expressions is always empty. Types representing lambda expressions are pseudo-elements and not included in the children of their parent. Lambda expressions are created as the result of a ICodeAssist.codeSelect(...). For more information on such pseudo-elements, see ILocalVariable.

If a binary type cannot be parsed, its structure remains unknown. Use IJavaElement.isStructureKnown to determine whether this is the case.

The children are of type IMember, which includes IField, IMethod, IInitializer and IType. The children are listed in the order in which they appear in the source or class file.

Caveat: The children of a binary type include nested types. However, the parent of such a nested binary type is not the enclosing type, but that nested type's IClassFile!

Returns:

the initializers declared by this type

Throws:

JavaModelException - if this element does not exist or if an exception occurs while accessing its corresponding resource.

getKey

String getKey()

If the given type is not resolved, the returned key is simply the java element's key.

Returns:

getMethod

IMethod getMethod(String name,

Returns the method with the specified name and parameter types in this type (for example, "foo", {"I", "QString;"}). To get the handle for a constructor, the name specified must be the simple name of the enclosing type. This is a handle-only method. The method may or may not be present.

The type signatures may be either unresolved (for source types) or resolved (for binary types), and either basic (for basic types) or rich (for parameterized types). See Signature for details. Note that the parameter type signatures for binary methods are expected to be dot-based.

Parameters:

name - the given name

parameterTypeSignatures - the given parameter types

Returns:

the method with the specified name and parameter types in this type

getMethods

IMethod[] getMethods()
              throws JavaModelException

For interfaces, the superclass name is always "java.lang.Object". For source types, the name as declared is returned, for binary types, the resolved, qualified name is returned. For anonymous types, the superclass name is the name appearing after the 'new' keyword'. If the superclass is a parameterized type, the string may include its type arguments enclosed in "<>". If the returned string is needed for anything other than display purposes, use getSuperclassTypeSignature() which returns a structured type signature string containing more precise information.

Returns:

the name of this type's superclass, or null for source types that do not specify a superclass

Throws:

JavaModelException - if this element does not exist or if an exception occurs while accessing its corresponding resource.

The type signatures may be either unresolved (for source types) or resolved (for binary types), and either basic (for basic types) or rich (for parameterized types). See Signature for details.

For classes, this gives the interfaces that this class implements. For interfaces, this gives the interfaces that this interface extends. An empty collection is returned if this type does not implement or extend any interfaces. For source types, simple names are returned, for binary types, qualified names are returned. For anonymous types, an empty collection is always returned. If the list of supertypes includes parameterized types, the string may include type arguments enclosed in "<>". If the result is needed for anything other than display purposes, use getSuperInterfaceTypeSignatures() which returns structured signature strings containing more precise information.

Returns the names of types that this sealed type permits to be its sub types. For a non sealed type, an empty array is returned. If type declares an explicit permits clause, then the permitted sub-types are returned in the declared order. If a sealed type does not explicitly declare permitted sub types, then the implicit permitted types, that is, the types in the same compilation unit that are sub types of this sealed type are returned in the order they appear within the compilation unit.

Returns:

names of types that this type permits to be its sub types

resolveType

String[][] resolveType(String typeName)
                throws JavaModelException

Resolves the given type name within the context of this type (depending on the type hierarchy and its imports).

Multiple answers might be found in case there are ambiguous matches.

Each matching type name is decomposed as an array of two strings, the first denoting the package name (dot-separated) and the second being the type name. The package name is empty if it is the default package. The type name is the type qualified name using a '.' enclosing type separator.

Returns null if unable to find any matching type.

For example, resolution of "Object" would typically return {{"java.lang", "Object"}}. Another resolution that returns {{"", "X.Inner"}} represents the inner type Inner defined in type X in the default package.
