ThrowingInsn

public final class ThrowingInsn extends Insn
Instruction which possibly throws. The successors list in the basic block an instance of this class is inside corresponds in-order to the list of exceptions handled by this instruction, with the no-exception case appended as the final target.

Fields Summary
private final com.android.dx.rop.type.TypeList
catches
non-null; list of exceptions caught
Constructors Summary
public ThrowingInsn(Rop opcode, SourcePosition position, RegisterSpecList sources, com.android.dx.rop.type.TypeList catches)
Constructs an instance.

param
opcode non-null; the opcode
param
position non-null; source position
param
sources non-null; specs for all the sources
param
catches non-null; list of exceptions caught

        super(opcode, position, null, sources);

        if (opcode.getBranchingness() != Rop.BRANCH_THROW) {
            throw new IllegalArgumentException("bogus branchingness");
        }

        if (catches == null) {
            throw new NullPointerException("catches == null");
        }

        this.catches = catches;

public java.lang.StringgetInlineString()
{@inheritDoc}

        return toCatchString(catches);
public static java.lang.StringtoCatchString(com.android.dx.rop.type.TypeList catches)
Gets the string form of a register spec list to be used as a catches list.

param

return
non-null; the string form
