Constructor Detail

AddressRangeImpl

public AddressRangeImpl(AddressRange range)

Construct a new AddressRangeImpl from the given range.

Parameters:

range - the address range to copy.

AddressRangeImpl

public AddressRangeImpl(Address start,
                        Address end)

Construct an AddressRange with the given start and end address. If the start address is before the end address, they are swapped to be in order.

Parameters:

start - start address in the range

end - end address in the range

Throws:

java.lang.IllegalArgumentException - thrown if the minimum and maximum addresses are not comparable.

AddressRangeImpl

public AddressRangeImpl(Address start,
                        long length)
                 throws AddressOverflowException

Construct an AddressRange with the given start address and length.

Parameters:

start - start address in the range

length - the length of the range.

Throws:

AddressOverflowException - if the length would wrap.
