public abstract class PsiAugmentProvider
extends java.lang.Object

Some code is not what it seems to be! This extension allows plugins augment a reality alter a behavior of Java PSI elements. To get an insight of how the extension may be used see PsiAugmentProviderTest.

Modifier and Type	Method and Description
static <Psi extends PsiElement> java.util.List<Psi>	collectAugments(PsiElement element, java.lang.Class<? extends Psi> type)
protected <Psi extends PsiElement> java.util.List<Psi>	getAugments(PsiElement element, java.lang.Class<Psi> type) An extension that enables one to add children to some PSI elements, e.g.
static PsiType	getInferredType(PsiTypeElement typeElement)
protected PsiType	inferType(PsiTypeElement typeElement) Extends PsiTypeElement.getType() so that a type could be retrieved from external place (e.g.
static java.util.Set<java.lang.String>	transformModifierProperties(PsiModifierList modifierList, Project project, java.util.Set<java.lang.String> modifiers)
protected java.util.Set<java.lang.String>	transformModifiers(PsiModifierList modifierList, java.util.Set<java.lang.String> modifiers) Intercepts PsiModifierList.hasModifierProperty(String), so that plugins can add imaginary modifiers or hide existing ones.

Method Detail

getAugments

protected <Psi extends PsiElement> java.util.List<Psi> getAugments(PsiElement element,
                                                                   java.lang.Class<Psi> type)

An extension that enables one to add children to some PSI elements, e.g. methods to Java classes. The class code remains the same, but its method accessors also include the results returned from PsiAugmentProviders.

inferType

protected PsiType inferType(PsiTypeElement typeElement)

Extends PsiTypeElement.getType() so that a type could be retrieved from external place (e.g. inferred from a variable initializer).

transformModifiers

protected java.util.Set<java.lang.String> transformModifiers(PsiModifierList modifierList,
                                                             java.util.Set<java.lang.String> modifiers)

Intercepts PsiModifierList.hasModifierProperty(String), so that plugins can add imaginary modifiers or hide existing ones.

collectAugments

public static <Psi extends PsiElement> java.util.List<Psi> collectAugments(PsiElement element,
                                                                           java.lang.Class<? extends Psi> type)

getInferredType

public static PsiType getInferredType(PsiTypeElement typeElement)

transformModifierProperties

public static java.util.Set<java.lang.String> transformModifierProperties(PsiModifierList modifierList,
                                                                          Project project,
