boolean	isReferenceTo(PsiElement element) Checks if the reference targets the specified element.
boolean	isSoft() Returns false if the underlying element is guaranteed to be a reference, or true if the underlying element is a possible reference which should not be reported as an error if it fails to resolve.

getAbsoluteRange

Constructor Detail

GenericDomValueReference

public GenericDomValueReference(GenericDomValue<T> domValue)

Method Detail

getPsiManager

protected final PsiManager getPsiManager()

createTextRange

protected TextRange createTextRange()

getGenericValue

protected final GenericDomValue<T> getGenericValue()

isSoft

public boolean isSoft()

Description copied from interface: PsiReference

Returns false if the underlying element is guaranteed to be a reference, or true if the underlying element is a possible reference which should not be reported as an error if it fails to resolve. For example, a text in an XML file which looks like a full-qualified Java class name is a soft reference.

Specified by:

isSoft in interface PsiReference

Overrides:

isSoft in class PsiReferenceBase<XmlElement>

Returns:

true if the reference is soft, false otherwise.

resolveInner

protected PsiElement resolveInner(T o)

isReferenceTo

public boolean isReferenceTo(PsiElement element)

Description copied from interface: PsiReference

Checks if the reference targets the specified element.

Specified by:

isReferenceTo in interface PsiReference

Overrides:

isReferenceTo in class PsiReferenceBase<XmlElement>

Parameters:

element - the element to check target for.

Returns:

true if the reference targets that element, false otherwise.

getConverter

public Converter<T> getConverter()

resolve

public PsiElement resolve()

Description copied from interface: PsiReference

Returns the element which is the target of the reference.

Specified by:

resolve in interface PsiReference

Returns:

the target element, or null if it was not possible to resolve the reference to a valid target.

See Also:

PsiPolyVariantReference.multiResolve(boolean)

getCanonicalText

public java.lang.String getCanonicalText()

Description copied from interface: PsiReference

Returns the name of the reference target element which does not depend on import statements and other context (for example, the full-qualified name of the class if the reference targets a Java class).

Specified by:

getCanonicalText in interface PsiReference

Overrides:

getCanonicalText in class PsiReferenceBase<XmlElement>

Returns:

the canonical text of the reference.

getUnresolvedMessagePattern

public java.lang.String getUnresolvedMessagePattern()

Description copied from interface: EmptyResolveMessageProvider

Returns custom unresolved message pattern. First, returned value is used as pattern in MessageFormat.format() call. If the call fails, returned value is used as is. Resulting text should have Sentence capitalization.

Specified by:

getUnresolvedMessagePattern in interface EmptyResolveMessageProvider

Returns:

pattern or message

getConvertContext

public final ConvertContext getConvertContext()

handleElementRename

public PsiElement handleElementRename(java.lang.String newElementName)
                               throws IncorrectOperationException

Description copied from interface: PsiReference

Called when the reference target element has been renamed, in order to change the reference text according to the new name.

Specified by:

handleElementRename in interface PsiReference

Overrides:

handleElementRename in class PsiReferenceBase<XmlElement>

Parameters:

newElementName - the new name of the target element.

Returns:

the new underlying element of the reference.

Throws:

IncorrectOperationException - if the rename cannot be handled for some reason.

bindToElement

public PsiElement bindToElement(PsiElement element)
                         throws IncorrectOperationException

Description copied from interface: PsiReference

Changes the reference so that it starts to point to the specified element. This is called, for example, by the "Create Class from New" quickfix, to bind the (invalid) reference on which the quickfix was called to the newly created class.

Specified by:

bindToElement in interface PsiReference

Overrides:

bindToElement in class PsiReferenceBase<XmlElement>

Parameters:

element - the element which should become the target of the reference.

Returns:

the new underlying element of the reference.

Throws:

IncorrectOperationException - if the rebind cannot be handled for some reason.

getVariants

public java.lang.Object [] getVariants()

Description copied from interface: PsiReference

Returns the array of String, PsiElement and/or LookupElement instances representing all identifiers that are visible at the location of the reference. The contents of the returned array is used to build the lookup list for basic code completion. (The list of visible identifiers may not be filtered by the completion prefix string - the filtering is performed later by the IDE.)

This method is default since 2018.3.

Specified by:

getVariants in interface PsiReference

Returns:

the array of available identifiers.

canResolveTo

public boolean canResolveTo(java.lang.Class<? extends PsiElement> elementClass)

Specified by:

canResolveTo in interface ResolvingHint
