public class BitString extends AbstractData
BitString class represents the BIT STRING type. BIT STRING values can store
binary data whose size is not a multiple of 8 bits.| Constructor and Description |
|---|
BitString()
The default constructor.
|
BitString(byte[] value)
Constructs the
BitString object from a byte array that contains bit values
(little endian). |
BitString(byte[] value,
int size)
Constructs the
BitString object from a byte array that contains bit values
(little endian). |
| Modifier and Type | Method and Description |
|---|---|
byte[] |
byteArrayValue()
Returns bit values of the
BitString in little endian format. |
void |
clearBit(int i)
Sets the value of the bit at the specified position to '0'.
|
java.lang.Object |
clone()
Creates a deep copy of
this object. |
boolean |
equals(java.lang.Object that)
Compares this object to another
BitString to see if they are equal. |
boolean |
getBit(int i)
Gets the value of the bit at the specified position.
|
int |
getSize()
Returns the
BitString size in bits. |
int |
hashCode()
Computes the hash code of this BitString.
|
void |
setBit(int i)
Sets the value of the bit at the specified position to '1'.
|
void |
setBit(int i,
boolean value)
Sets the value of the bit at the specified position.
|
void |
setValue(byte[] value,
int size)
Sets the bit values of the
BitString. |
public BitString()
BitString to the default value
(an empty bit string).public BitString(byte[] value)
BitString object from a byte array that contains bit values
(little endian). The size of the bit string is set to value.length * 8.value - specifies bit values in little endian format.public BitString(byte[] value,
int size)
BitString object from a byte array that contains bit values
(little endian). If the specified size exceeds the capacity of
the value, the value is padded with the appropriate number of zero bits.value - specifies bit values in little endian format.size - specifies bit string size in bits.public final byte[] byteArrayValue()
BitString in little endian format.BitString.public final void setValue(byte[] value,
int size)
BitString. If the specified
size exceeds the capacity of the value, the value is padded with
the appropriate number of zero bits.value - specifies bit values in little endian format.size - specifies the bit string size in bits.public final int getSize()
