Interface ArrayLoadInstruction

All Superinterfaces:

ClassFileElement, CodeElement, Instruction

public sealed interface ArrayLoadInstruction
extends Instruction

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

An array load instruction is composite:

ArrayLoadInstruction(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 load instruction baload also operates on boolean arrays, so this never returns boolean.

Returns:

the component type of the array

of

static ArrayLoadInstruction of(Opcode op)

Returns an array load instruction.

Parameters:

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

Returns:

an array load instruction

Throws:

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