KaCompoundArrayAccessCall

KaCompoundArrayAccessCall represents a compound array-like access convention involving calls to both get() and set(), e.g. a[1] += "foo".

fun test(m: MutableMap<String, String>) {
    m["a"] += "b"
}

The above desugars into m.get("a").plus("b") followed by m.set("a", ...). The compound call captures all three operator calls plus the index arguments.

Hierarchy

Inherits KaMultiCall. (It also inherits the legacy KaCall for historical reasons.)

Members

val getterCall: KaFunctionCall<KaNamedFunctionSymbol>: The get function call invoked when reading values corresponding to the given indexArguments.
val setterCall: KaFunctionCall<KaNamedFunctionSymbol>: The set function call invoked when writing the computed value corresponding to the given indexArguments.
val indexArguments: List<KtExpression>: The arguments representing the indices in the index access operator.

m1["a"] += "b"   // a single index argument: "a"
m2[1, 5] += 12   // two index arguments: 1 and 5

val compoundOperation: KaCompoundOperation: The compound operation kind. See KaCompoundOperation. compoundOperation.operationCall gives the resolved operator function call (e.g. String.plus for +=); the operation call is also available directly on the inherited KaCompoundAccessCall.operationCall.
val getPartiallyAppliedSymbol: KaPartiallyAppliedFunctionSymbol<KaNamedFunctionSymbol> — deprecated: Legacy wrapper around the get function. Replaced by getterCall.
val setPartiallyAppliedSymbol: KaPartiallyAppliedFunctionSymbol<KaNamedFunctionSymbol> — deprecated: Legacy wrapper around the set function. Replaced by setterCall.
