Properties

opcode

val opcode: StyleRuleInstruction.StyleRuleInstructionOpcode

The opcode of the associated instruction.

Functions

emitOn

open fun emitOn(nybbles: NybbleOutputStream, vararg operands: Int)

Encode the associated instruction onto the specified NybbleOutputStream. Subclasses should call the superimplementation to ensure that the opcode is correctly encoded. This protocol exists to permit the code generator to emit instructions without instantiating them.

toString

open override fun toString(): String
