public LookupSwitchBuilder()

Builds a lookup switch statement with no specified default location. When the lookup switch is added to the code attribute a BranchEnd will be returned that can be used to set the location.

public LookupSwitchBuilder(final CodeLocation defaultLocation)

Builds a lookup switch statement, specifying the default location

Parameters
defaultLocation:CodeLocation

The default location

Method Detail

addback to summary
public AtomicReference<BranchEnd> add(int value)

Adds a value to the table that is at a location yet to be written. After this lookup switch has been written then the BranchEnd can be retrieved from the returned reference.

Parameters
value:int

The value to add to the lookup table

Returns:AtomicReference<BranchEnd>

A reference to the BranchEnd that will be created.

public LookupSwitchBuilder add(int value, final CodeLocation location)

Parameters
value:int

The value to add to the lookup table

Method Detail

compareToback to summary
public int compareTo(final LookupSwitchBuilder.ValuePair o)

Implements java.lang.Comparable.compareTo.

Doc from java.lang.Comparable.compareTo.

Compares this object with the specified object for order. Returns a negative integer, zero, or a positive integer as this object is less than, equal to, or greater than the specified object.

The implementor must ensure signum(x.compareTo(y)) == -signum(y.compareTo(x)) for all x and y. (This implies that x.compareTo(y) must throw an exception if and only if y.compareTo(x) throws an exception.)

The implementor must also ensure that the relation is transitive: (x.compareTo(y) > 0 && y.compareTo(z) > 0) implies x.compareTo(z) > 0.

Finally, the implementor must ensure that x.compareTo(y)==0 implies that signum(x.compareTo(z)) == signum(y.compareTo(z)), for all z.

Parameters
o:LookupSwitchBuilder.ValuePair

the object to be compared.

Returns:int

a negative integer, zero, or a positive integer as this object is less than, equal to, or greater than the specified object.
