Interface ConvertInstruction

All Superinterfaces:: ClassFileElement, CodeElement, Instruction

public sealed interface ConvertInstruction extends Instruction

Models a primitive conversion instruction in the code array of a Code attribute, such as i2l. Corresponding opcodes have a kind of Opcode.Kind.CONVERT. Delivered as a CodeElement when traversing the elements of a CodeModel.

A primitive conversion instruction is composite:

ConvertInstruction(
    TypeKind fromType,
    TypeKind toType
)

where these conversions are valid:

Between int, long, float, and double, where fromType != toType;
From int to byte, char, and short.

Method Details

fromType

TypeKind fromType()

Returns the source type to convert from.

Returns:: the source type to convert from

toType

TypeKind toType()

Returns the destination type to convert to.

Returns:: the destination type to convert to

of

static ConvertInstruction of(TypeKind fromType, TypeKind toType)

Returns a conversion instruction. Valid conversions are:

Between int, long, float, and double, where fromType != toType;
From int to byte, char, and short.

Parameters:: fromType - the type to convert from; toType - the type to convert to
Returns:: a conversion instruction
Throws:: IllegalArgumentException - if this is not a valid conversion

of

static ConvertInstruction of(Opcode op)

Returns a conversion instruction.

Parameters:: op - the opcode for the specific type of conversion instruction, which must be of kind Opcode.Kind.CONVERT
Returns:: a conversion instruction
Throws:: IllegalArgumentException - if the opcode kind is not Opcode.Kind.CONVERT.
