Method Detail

getBit

public boolean getBit(int index)

Parameters:

index - : the nth number bit to get from the bit string

Returns:

boolean bit, true if the bit is switched to 1, false otherwise

setBit

public void setBit(int index)

Parameters:

index - : set the nth number bit from the bit string

unsetBit

public void unsetBit(int index)

Parameters:

index - : unset the nth number bit from the bit string

getInt

public int getInt(int startInclusive,
                  int size)
           throws VendorConsentException

interprets n number of bits as a big endiant int

Parameters:

startInclusive - : the nth to begin interpreting from

size - : the number of bits to interpret

Returns:

integer value

Throws:

VendorConsentException - when the bits cannot fit in an int sized field

setInt

public void setInt(int startInclusive,
                   int size,
                   int to)
            throws VendorConsentException

Writes an integer value into a bit array of given size

Parameters:

startInclusive - : the nth to begin writing to

size - : the number of bits available to write

to - : the integer to write out

Throws:

VendorConsentException - when the bits cannot fit into the provided size

getInstantFromEpochDeciseconds

public Instant getInstantFromEpochDeciseconds(int startInclusive,
                                              int size)
                                       throws VendorConsentException

returns an Instant derived from interpreting the given interval on the bit string as long representing the number of demiseconds from the unix epoch

Parameters:

startInclusive - : the bit from which to begin interpreting

size - : the number of bits to interpret

Returns:

instant value

Throws:

VendorConsentException - when the number of bits requested cannot fit in a long

setInstantToEpochDeciseconds

public void setInstantToEpochDeciseconds(int startInclusive,
                                         int size,
                                         Instant instant)
                                  throws VendorConsentException

Throws:

VendorConsentException

getSixBitString

public String getSixBitString(int startInclusive,
                              int size)
                       throws VendorConsentException

This method interprets the given interval in the bit string as a series of six bit characters, where 0=A and 26=Z

Parameters:

startInclusive - : the nth bit in the bitstring from which to start the interpretation

size - : the number of bits to include in the string

Returns:

the string given by the above interpretation

Throws:

VendorConsentException - when the requested interval is not a multiple of six

setSixBitString

public void setSixBitString(int startInclusive,
                            int size,
                            String to)
                     throws VendorConsentException

This method interprets characters, as 0=A and 26=Z and writes to the given interval in the bit string as a series of six bits

Parameters:

startInclusive - : the nth bit in the bitstring from which to start writing

size - : the size of the bitstring

to - : the string given by the above interpretation

Throws:

VendorConsentException - when the requested interval is not a multiple of six
