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.

      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.
