DETAIL: FIELD | CONSTR | METHOD

org.eclipse.jdt.core
Interface IType

All Superinterfaces:: IAdaptable, IAnnotatable, IJavaElement, IMember, IParent, ISourceManipulation, ISourceReference

public interface IType
extends IMember, IAnnotatable
extends IMember, IAnnotatable

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. Enumeration classes and annotation types are subkinds of classes and interfaces, respectively.

Note that the element name of an anonymous source type is always empty.

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.

Restriction:: This interface is not intended to be implemented by clients.

If the type has access to its source code and the insertion position is valid, then completion is performed against the source. Otherwise the completion is performed against the type structure and the given locals variables.

Parameters:: snippet - the code snippet; insertion - the position with in source where the snippet is inserted. This position must not be in comments. A possible value is -1, if the position is not known.; position - the position within snippet where the user is performing code assist.; localVariableTypeNames - an array (possibly empty) of fully qualified type names of local variables visible at the current scope; localVariableNames - an array (possibly empty) of local variable names that are visible at the current scope; localVariableModifiers - an array (possible empty) of modifiers for local variables; isStatic - whether the current scope is in a static context; requestor - the completion requestor
Throws:: JavaModelException - if this element does not exist or if an exception occurs while accessing its corresponding resource.

JavaModelException

Deprecated. Use codeComplete(char[],int,int,char[][],char[][],int[],boolean,CompletionRequestor,WorkingCopyOwner) instead.

Do code completion inside a code snippet in the context of the current type. It considers types in the working copies with the given owner first. In other words, the owner's working copies will take precedence over their original compilation units in the workspace.

Note that if a working copy is empty, it will be as if the original compilation unit had been deleted.

If the type has access to its source code and the insertion position is valid, then completion is performed against the source. Otherwise the completion is performed against the type structure and the given locals variables.

Parameters:: snippet - the code snippet; insertion - the position with in source where the snippet is inserted. This position must not be in comments. A possible value is -1, if the position is not known.; position - the position with in snippet where the user is performing code assist.; localVariableTypeNames - an array (possibly empty) of fully qualified type names of local variables visible at the current scope; localVariableNames - an array (possibly empty) of local variable names that are visible at the current scope; localVariableModifiers - an array (possible empty) of modifiers for local variables; isStatic - whether the current scope is in a static context; requestor - the completion requestor; owner - the owner of working copies that take precedence over their original compilation units
Throws:: JavaModelException - if this element does not exist or if an exception occurs while accessing its corresponding resource.
