 EDU.purdue.cs.bloat.editor.Switch
| Switch | | public class Switch (Code) | | Switch is used to hold the lookup values and branch targets of a tableswitch
or lookup switch instruction.
The tableswitch low-to-high range of values is represented by storing each
lookup value in the range. This allows the tableswitch to be replaced with a
lookupswitch if branches are deleted.

| Constructor Summary | |
| public | Switch(Label defaultTarget, Label[] targets, int[] values)
Constructor.
Parameters:
defaultTarget - The default target of the switch.
Parameters:
targets - The non-default branch targets of the switch.
Parameters:
values - The lookup values of the switch. |
| Method Summary | |
| public Label | defaultTarget()
Get the default target of the switch. | | public boolean | hasContiguousValues()
Check if the all the values in the range of lookup values are contiguous.
If they are, a table switch can be used. | | public int | highValue()
Get the high value in the range the lookup values. | | public int | lowValue()
Get the low value in the range the lookup values. | | public void | setDefaultTarget(Label target)
Set the default target of the switch. | | public Label[] | targets()
Get the non-default branch targets of the switch. | | public String | toString()
Convert the operand to a string. | | public int[] | values()
Get the lookup values of the switch, sorted low to high. |
| Switch | | public Switch(Label defaultTarget, Label[] targets, int[] values)(Code) | | Constructor.
Parameters:
defaultTarget - The default target of the switch.
Parameters:
targets - The non-default branch targets of the switch.
Parameters:
values - The lookup values of the switch. This array must be the samesize as the targets array. |
| defaultTarget | | public Label defaultTarget()(Code) | | Get the default target of the switch.
The default target of the switch. |
| hasContiguousValues | | public boolean hasContiguousValues()(Code) | | Check if the all the values in the range of lookup values are contiguous.
If they are, a table switch can be used. If not a lookupswitch can be
used.
true if contiguous, false if not. |
| highValue | | public int highValue()(Code) | | Get the high value in the range the lookup values.
The high value. |
| lowValue | | public int lowValue()(Code) | | Get the low value in the range the lookup values.
The low value. |
| setDefaultTarget | | public void setDefaultTarget(Label target)(Code) | | Set the default target of the switch.
Parameters:
target - The default target of the switch. |
| targets | | public Label[] targets()(Code) | | Get the non-default branch targets of the switch. The targets are sorted
by the corresponding lookup value.
The non-default branch targets of the switch. |
| toString | | public String toString()(Code) | | Convert the operand to a string.
A string representation of the operand. |
| values | | public int[] values()(Code) | | Get the lookup values of the switch, sorted low to high.
The lookup values of the switch. |
