Field Detail

TYPE

public static final DataType TYPE

Deprecated.

Convenience access member for DataType.getType(BitVectorCell.class).

DataType.getType(Class)

Constructor Detail

BitVectorCell

public BitVectorCell(String hex)

Deprecated.

Create new BitVectorCell with a predefined value, read from a string which holds a hexadecimal representation. Resulting bit vector assumes lowest-to-highest order in blocks of 32 bits.

Parameters:

hex - the hexadecimal representation of the bit vector's value

Throws:

NumberFormatException - if that fails

BitVectorCell

public BitVectorCell(BitSet bits,
                     int nrOfBits)

Deprecated.

Creates a new BitVectorCell based on a BitSet and a fixed length for the bits.

Parameters:

bits - the bit set to be put in the cell

nrOfBits - the number for the fixed length of the cell

Method Detail

getPreferredValueClass

public static final Class<? extends DataValue> getPreferredValueClass()

Deprecated.

Preferred value class of a BitVectorCell is BitVectorValue. This method is called per reflection.

Returns:

BitVectorValue.class

See Also:

DataCell

toHexString

public String toHexString()

Deprecated.

Provide inverse routing, converting a bit vector into the corresponding hexadecimal representation.

Specified by:

toHexString in interface BitVectorValue

Returns:

hex representation

oldWay

static BitSet oldWay(String hex)

Deprecated.

The old way of constructing the bitvector cell's bitvector. Create new BitVectorCell with a predefined value, read from a string which holds a hexadecimal representation. Resulting bit vector assumes highest-to-lowest order, that is, the bits for the 2^3 will be left-most in each group of 4 bits. Other than that the 4-bit groups will follow the order of hex characters.

Parameters:

hex - the hexadecimal representation of the bit vector's value

Returns:

the corresponding bit set

getNumBits

public int getNumBits()

Deprecated.

Specified by:

getNumBits in interface BitVectorValue

Returns:

number of bits actually used

getBitSet

public BitSet getBitSet()

Deprecated.

Specified by:

getBitSet in interface BitVectorValue

Returns:

the underlying bit set

See Also:

BitSet

toString

public String toString()

Deprecated.

Description copied from class: DataCell

Returns the String representation of this cell's value.

Specified by:

toString in class DataCell

Returns:

a bit string

getIntValue

public int getIntValue()

Deprecated.

Returns cardinality of this bit vector.

Returns:

cardinality of this bit vector

See Also:

IntValue.getIntValue()

equalsDataCell

public boolean equalsDataCell(DataCell o)

Deprecated.

Check if two BitVectorCells are equal.

Specified by:

equalsDataCell in class DataCell

Parameters:

o - the other object to check

Returns:

true if this instance and the given object are instances of the same class and their string representations are equal

See Also:

Object.equals(Object)

hashCode

public int hashCode()

Deprecated.

This method must be implemented in order to ensure that two equal DataCell objects return the same hash code.

Specified by:

hashCode in class DataCell

Returns:

the hash code of your specific DataCell

See Also:

Object.hashCode(), DataCell.equals(java.lang.Object)

save

public void save(Config config)

Deprecated.

Saves this cell to the config.

Parameters:

config - to write into it

See Also:

toString()

load

public static DataCell load(Config config)
                     throws InvalidSettingsException

Deprecated.

Loads a new cell using the properties from the given config.

Parameters:

config - the config to get String from and inits this cell

Returns:

a new bit vector cell

Throws:

InvalidSettingsException - if the value is not available
