All Implemented Interfaces:
ToHuman
public final class SwitchInsn extends Insn
Instruction which contains switch cases.

  • Constructor Details

    • SwitchInsn

      public SwitchInsn(Rop opcode, SourcePosition position, RegisterSpec result, RegisterSpecList sources, IntList cases)
      Constructs an instance.
      Parameters:
      opcode - non-null; the opcode
      position - non-null; source position
      result - null-ok; spec for the result, if any
      sources - non-null; specs for all the sources
      cases - non-null; list of switch cases

  • Method Details

    • getInlineString

      public String getInlineString()
      Gets an "inline" string portion for toHuman(), if available. This is the portion that appears after the Rop opcode
      Overrides:
      getInlineString in class Insn
      Returns:
      null-ok; if non-null, the inline text for toHuman()

    • getCatches

      public TypeList getCatches()
      Gets the list of possibly-caught exceptions. This returns StdTypeList.EMPTY if this instruction has no handlers, which can be either if this instruction can't possibly throw or if it merely doesn't handle any of its possible exceptions. To determine whether this instruction can throw, use Insn.canThrow().
      Specified by:
      getCatches in class Insn
      Returns:
      non-null; the catches list

    • accept

      public void accept(Insn.Visitor visitor)
      Calls the appropriate method on the given visitor, depending on the class of this instance. Subclasses must override this.
      Specified by:
      accept in class Insn
      Parameters:
      visitor - non-null; the visitor to call on

    • withAddedCatch

      public Insn withAddedCatch(Type type)
      Returns an instance that is just like this one, except that it has a catch list with the given item appended to the end. This method throws an exception if this instance can't possibly throw. To determine whether this instruction can throw, use Insn.canThrow().
      Specified by:
      withAddedCatch in class Insn
      Parameters:
      type - non-null; type to append to the catch list
      Returns:
      non-null; an appropriately-constructed instance

    • withRegisterOffset

      public Insn withRegisterOffset(int delta)
      Returns an instance that is just like this one, except that all register references have been offset by the given delta.
      Specified by:
      withRegisterOffset in class Insn
      Parameters:
      delta - the amount to offset register references by
      Returns:
      non-null; an appropriately-constructed instance

    • contentEquals

      public boolean contentEquals(Insn b)
      Compares Insn contents, since Insn.equals() is defined to be an identity compare. Insn's are contentEquals() if they have the same opcode, registers, source position, and other metadata.

      SwitchInsn always compares false. The current use for this method never encounters SwitchInsns

      Overrides:
      contentEquals in class Insn
      Returns:
      true in the case described above

    • withNewRegisters

      public Insn withNewRegisters(RegisterSpec result, RegisterSpecList sources)
      Returns an instance that is just like this one, except with new result and source registers.
      Specified by:
      withNewRegisters in class Insn
      Parameters:
      result - null-ok; new result register
      sources - non-null; new sources registers
      Returns:
      non-null; an appropriately-constructed instance

    • getCases

      public IntList getCases()
      Gets the list of switch cases.
      Returns:
      non-null; the case list
