public sealed Interface ArrayLoadInstruction

Known Direct Implementers: jdk.internal.classfile.impl.AbstractInstruction.UnboundArrayLoadInstruction
Imports: java.lang.classfile.CodeBuilder, .CodeElement, .CodeModel, .Instruction, .Opcode, .TypeKind, jdk.internal.classfile.impl.AbstractInstruction, .Util

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.

Since: 24

public static ArrayLoadInstruction of(Opcode op)

Returns an array load instruction.

Parameters

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

Returns:ArrayLoadInstruction

an array load instruction

Exceptions

IllegalArgumentException:: if the opcode kind is not Opcode.Kind#ARRAY_LOAD

typeKind back to summary

typeKind	back to summary
public 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:TypeKind the component type of the array

public 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:TypeKind: the component type of the array
