KaDelegatedPropertyCall

Represents a resolved delegated property, which desugars into up to three operator calls: getValue(), setValue(), and provideDelegate().

Example

val name: String by lazy { "John" }

A delegated val property desugars to:

val name$delegate = lazy { "John" }
val name: String get() = name$delegate.getValue(thisRef, property)

For a var property, a setValue call is also generated. If the delegate expression defines a provideDelegate operator, it is called first.

calls

abstract val calls: List<KaSimpleCall<*, *>>

The non-empty list of KaSimpleCalls that were discovered during resolution of KtResolvableCall

calls

The list of KaCalls associated with the KaCallInfo. The list contains a single KaCall in case of a successful call, but may contain multiple candidates in case of an error call.

The flattened list of resolved calls.

The flattened list of KaSimpleCalls.

constructor

this call as a call to a constructor, or null if it is not a constructor call.

Example

annotation class Anno

class Foo

@Anno
fun usage() {
   Foo()
}

Both the Foo() call and the @Anno annotation entry are constructor calls, so constructor returns the call itself.

function

this call as a KaFunctionCall, or null if it is not a call to a function.

Example

class Foo {
   fun function() {}
   var int: Int = 1
}

fun Foo.usage() {
   function()
   int
}

For function(), function is the call to function. For int, which is a KaVariableAccessCall, function is null.

See also

provideDelegateCall

The provideDelegate() operator call. null if not applicable.

simple

this call as a KaSimpleCall, or null if it is a KaMultiCall.

Example

var int: Int = 1

fun usage() {
   int = 2
   int++
}

For int = 2, simple is the write access to int. For int++, which is a KaMultiCall, simple is null.

symbols

The flattened list of KaSymbols for the resolved calls.

A list of KaSymbol.

token

abstract val token: KaLifetimeToken

The KaLifetimeToken which determines the lifetime of the lifetime owner.

valueGetterCall

The getValue() operator call on the delegate object.

valueSetterCall

The setValue() operator call on the delegate object. null for val properties.

variable

this call as a KaVariableAccessCall, or null if it is not an access to a variable.

Example

class Foo {
   fun function() {}
   var int: Int = 1
}

fun Foo.usage() {
   int
   function()
}

For int, variable is the read access to int. For function(), which is a KaFunctionCall, variable is null.

Functions

assertIsValidAndAccessible

isValid

Whether the lifetime owner is still valid, i.e. we are still in the scope of the lifetime owner's regular lifetime.

withValidityAssertion

inline fun <R> KaLifetimeOwner.withValidityAssertion(action: () -> R): R

Executes action only if the KaLifetimeOwner is still valid and accessible. Otherwise, throws a validity exception based on the concrete violation.
