Method Detail

parameterReferenced

public void parameterReferenced(boolean forWriting)

Description copied from interface: RefParameter

Marks the parameter as referenced for reading or writing.

Specified by:

parameterReferenced in interface RefParameter

Parameters:

forWriting - true if the parameter is marked as referenced for writing, false otherwise.

isUsedForReading

public boolean isUsedForReading()

Description copied from interface: RefParameter

Checks if the parameter is used for reading.

Specified by:

isUsedForReading in interface RefParameter

Returns:

true if the parameter has read accesses, false otherwise.

getUsageCount

public int getUsageCount()

Specified by:

getUsageCount in interface RefParameter

isUsedForWriting

public boolean isUsedForWriting()

Description copied from interface: RefParameter

Checks if the parameter is used for writing.

Specified by:

isUsedForWriting in interface RefParameter

Returns:

true if the parameter has write accesses, false otherwise.

accept

public void accept(RefVisitor visitor)

Description copied from interface: RefEntity

Accepts the specified visitor and passes self to one of its visit methods.

Specified by:

accept in interface RefEntity

Overrides:

accept in class RefEntityImpl

Parameters:

visitor - the visitor to accept.

getIndex

public int getIndex()

Description copied from interface: RefParameter

Returns the index of the parameter in the parameter list of its owner method.

Specified by:

getIndex in interface RefParameter

Returns:

the index of the parameter.

buildReferences

public void buildReferences()

Overrides:

buildReferences in class RefElementImpl

getActualConstValue

public java.lang.Object getActualConstValue()

Description copied from interface: RefParameter

If all invocations of the method pass the same value to the parameter, returns that value (the name of a static final field or the text of a literal expression). Otherwise, returns RefParameter.VALUE_IS_NOT_CONST.

Specified by:

getActualConstValue in interface RefParameter

Returns:

the parameter value or null if it's different or impossible to determine.

initialize

protected void initialize()

Specified by:

initialize in class RefElementImpl

getExternalName

public java.lang.String getExternalName()

Description copied from interface: RefEntity

Returns a user-readable name for the element corresponding to the node.

Specified by:

getExternalName in interface RefEntity

Overrides:

getExternalName in class RefElementImpl

Returns:

the user-readable name.

getUastElement

public UParameter getUastElement()

Specified by:

getUastElement in interface RefJavaElement

Specified by:

getUastElement in interface RefParameter

getAccessibleExpressionValue

public static java.lang.Object getAccessibleExpressionValue(UExpression expression,
                                                            java.util.function.Supplier<? extends PsiElement> accessPlace)
