Constructor Details

ASN1BitString

public ASN1BitString(@NotNull
 boolean... bits)

Creates a new ASN.1 bit string element with the default BER type and the provided set of bits.

Parameters:

bits - The bits to include in the bit string. Each boolean value of true represents a bit of one, and each boolean value of false represents a bit of zero. It must not be null but may be empty.

ASN1BitString

public ASN1BitString(byte type,
 @NotNull
 boolean... bits)

Creates a new ASN.1 bit string element with the specified BER type and the provided set of bits.

Parameters:

type - The BER type to use for this element.

bits - The bits to include in the bit string. Each boolean value of true represents a bit of one, and each boolean value of false represents a bit of zero. It must not be null but may be empty.

ASN1BitString

public ASN1BitString(@NotNull
 String stringRepresentation)
              throws ASN1Exception

Creates a new ASN.1 bit string with the default BER type and a value created from the provided string representation.

Parameters:

stringRepresentation - A string representation of the bit string to create. It must not be null, but may be empty. It must be comprised only of the characters '1' and '0'.

Throws:

ASN1Exception - If the provided string does not represent a valid bit string value.

ASN1BitString

public ASN1BitString(byte type,
 @NotNull
 String stringRepresentation)
              throws ASN1Exception

Creates a new ASN.1 bit string with the default BER type and a value created from the provided string representation.

Parameters:

type - The BER type to use for this element.

stringRepresentation - A string representation of the bit string to create. It must not be null, but may be empty. It must be comprised only of the characters '1' and '0'.

Throws:

ASN1Exception - If the provided string does not represent a valid bit string value.

Method Details

getBits

@NotNull
public boolean[] getBits()

Retrieves an array of boolean values that correspond to the bits in this bit string. Each boolean value of true represents a bit of one, and each boolean value of false represents a bit of zero.

Returns:

An array of boolean values that correspond to the bits in this bit string.

getBytes

@NotNull
public byte[] getBytes()
                throws ASN1Exception

Retrieves the bytes represented by the bits that comprise this bit string, if the number of bits is a multiple of eight.

Returns:

The bytes represented by the bits that comprise this bit string.

Throws:

ASN1Exception - If the number of bits in this bit string is not a multiple of eight.

getBitsForBytes

@NotNull
public static boolean[] getBitsForBytes(@NotNull
 byte... bytes)
