All Superinterfaces:

ClassFileElement, CodeElement, Instruction

public sealed interface ArrayStoreInstruction
extends Instruction

Models an array store instruction in the code array of a Code attribute. Corresponding opcodes have a kind of Opcode.Kind.ARRAY_STORE. Delivered as a CodeElement when traversing the elements of a CodeModel.

An array store instruction is composite:

ArrayStoreInstruction(TypeKind typeKind)

where typeKind is not void, and boolean is converted to byte.

Method Details

typeKind

TypeKind typeKind()

Returns the component type of the array. The byte type store instruction bastore also operates on boolean arrays, so this never returns boolean.

Returns:

the component type of the array

of

static ArrayStoreInstruction of(Opcode op)

Returns an array store instruction.

Parameters:

op - the opcode for the specific type of array store instruction, which must be of kind Opcode.Kind.ARRAY_STORE

Returns:

an array store instruction

Throws:

IllegalArgumentException - if the opcode kind is not Opcode.Kind.ARRAY_STORE
