Constructor Detail

HardLocationImpl

public HardLocationImpl(cern.colt.bitvector.BitVector address,
                        int wordLength)

Constructs a new hard location with specified address and length.

Parameters:

address - BitVector

wordLength - length of the words

HardLocationImpl

public HardLocationImpl(cern.colt.bitvector.BitVector address)

Constructs a new hard location with specified address

Parameters:

address - BitVector address of this HardLocation

Method Detail

getAddress

public cern.colt.bitvector.BitVector getAddress()

Description copied from interface: HardLocation

Gets address

Specified by:

getAddress in interface HardLocation

Returns:

the address of this HardLocation

setAddress

public void setAddress(cern.colt.bitvector.BitVector address)

Description copied from interface: HardLocation

Sets the address of this HardLocation in the vector space

Specified by:

setAddress in interface HardLocation

Parameters:

address - the BitVector address to set

getCounters

public byte[] getCounters()

Description copied from interface: HardLocation

Returns the counters of this HardLocation Each HardLocation has wordSize counters. Each counter is byte size. Counters are incremented or decremented when the memory is written.

Specified by:

getCounters in interface HardLocation

Returns:

the counters of this HardLocation

getWriteCount

public int getWriteCount()

Description copied from interface: HardLocation

Gets write count

Specified by:

getWriteCount in interface HardLocation

Returns:

the number of times that this HardLocation was written to.

write

public void write(cern.colt.bitvector.BitVector word)

Description copied from interface: HardLocation

Writes specified BitVector to this HardLocation. For each bit in word, the corresponding counter is incremented if the bit is 1 or decremented if the bit is 0.

Specified by:

write in interface HardLocation

Parameters:

word - word to be written

setCounters

public void setCounters(byte[] newCounters)

Description copied from interface: HardLocation

Sets the counters of this HardLocation Each HardLocation has wordSize counters. Each counter is byte size. Counters are incremented or decremented when the memory is written.

Specified by:

setCounters in interface HardLocation

Parameters:

newCounters - new counters

read

public int[] read(int[] buff)

Description copied from interface: HardLocation

Reads this HardLocation. The binary vector read from this hard location is added to the int[] buffer.

Specified by:

read in interface HardLocation

Parameters:

buff - an int[] buffer where the result of the read is added

Returns:

the updated int[] buffer

hammingDistance

public int hammingDistance(cern.colt.bitvector.BitVector vector)

Description copied from interface: HardLocation

Returns the Hamming distance between a BitVector and the address of this HardLocation

Specified by:

hammingDistance in interface HardLocation

Parameters:

vector - BitVector to be compared with this HardLocation

Returns:

the Hamming distance.
