Class ImportRewrite.ImportRewriteContext

java.lang.Object

org.eclipse.jdt.core.dom.rewrite.ImportRewrite.ImportRewriteContext

Enclosing class:

ImportRewrite

public abstract static class ImportRewrite.ImportRewriteContext
extends Object

A ImportRewrite.ImportRewriteContext can optionally be used in e.g. ImportRewrite.addImport(String, ImportRewrite.ImportRewriteContext) to give more information about the types visible in the scope. These types can be for example inherited inner types where it is unnecessary to add import statements for.

This class can be implemented by clients.

Field Summary

Fields

Modifier and Type	Field	Description
static final int	KIND_STATIC_FIELD	Kind constant specifying that the element is a static field import.
static final int	KIND_STATIC_METHOD	Kind constant specifying that the element is a static method import.
static final int	KIND_TYPE	Kind constant specifying that the element is a type import.
static final int	RES_NAME_CONFLICT	Result constant signaling that the given element is conflicting with an other element in the context.
static final int	RES_NAME_FOUND	Result constant signaling that the given element is know in the context.
static final int	RES_NAME_UNKNOWN	Result constant signaling that the given element is not know in the context.
static final int	RES_NAME_UNKNOWN_NEEDS_EXPLICIT_IMPORT	Result constant signaling that the given element must be imported explicitly (and must not be folded into an on-demand import or filtered as an implicit import).

Method Summary

Modifier and Type	Method	Description
abstract int	findInContext(String qualifier, String name, int kind)	Searches for the given element in the context and reports if the element is known (RES_NAME_FOUND), unknown (RES_NAME_UNKNOWN), unknown in the context but known to require an explicit import (RES_NAME_UNKNOWN_NEEDS_EXPLICIT_IMPORT), or if its name conflicts (RES_NAME_CONFLICT) with an other element.
IAnnotationBinding[]	removeRedundantTypeAnnotations(IAnnotationBinding[] annotations, ImportRewrite.TypeLocation location, ITypeBinding type)	This method can be overridden in subclasses to remove annotations that are redundant, e.g. because of NonNullByDefault.

Method Details

findInContext

public abstract int findInContext(String qualifier,
 String name,
 int kind)

Searches for the given element in the context and reports if the element is known (RES_NAME_FOUND), unknown (RES_NAME_UNKNOWN), unknown in the context but known to require an explicit import (RES_NAME_UNKNOWN_NEEDS_EXPLICIT_IMPORT), or if its name conflicts (RES_NAME_CONFLICT) with an other element.

Parameters:

qualifier - The qualifier of the element, can be package or the qualified name of a type

name - The simple name of the element; either a type, method or field name or * for on-demand imports.

kind - The kind of the element. Can be either KIND_TYPE, KIND_STATIC_FIELD or KIND_STATIC_METHOD. Implementors should be prepared for new, currently unspecified kinds and return RES_NAME_UNKNOWN by default.

Returns:

Returns the result of the lookup. Can be either RES_NAME_FOUND, RES_NAME_UNKNOWN, RES_NAME_CONFLICT, or RES_NAME_UNKNOWN_NEEDS_EXPLICIT_IMPORT.

removeRedundantTypeAnnotations

public IAnnotationBinding[] removeRedundantTypeAnnotations(IAnnotationBinding[] annotations,
 ImportRewrite.TypeLocation location,
 ITypeBinding type)

This method can be overridden in subclasses to remove annotations that are redundant, e.g. because of NonNullByDefault.

Parameters:

annotations - The array of type annotations to be filtered.

location - Specifies how the type being annotated will be used.

type - the type being annotated

Returns:

Returns the annotations that should be added to the type.
