Method Summary

Modifier and Type	Method and Description
static byte[]	parseString(java.lang.String value) This overloaded version of the parseString method sets the numbits holder value to null.
static byte[]	parseString(java.lang.String value, IntHolder numbits) This static method parses the given ASN.1 value text (either a binary or hex data string) and returns the value in a binary byte array.
static boolean	stringEqualsBytes(java.lang.String value, byte[] data) This static method parses the given ASN.1 value text (either a binary or hex data string) and compares it with the given byte array.
static boolean	stringEqualsBytes(java.lang.String value, byte[] data, int nbits) This static method parses the given ASN.1 value text (either a binary or hex data string) and compares it with the given byte array.

Method Detail

stringEqualsBytes

public static boolean stringEqualsBytes(java.lang.String value,
                                        byte[] data)

This static method parses the given ASN.1 value text (either a binary or hex data string) and compares it with the given byte array. Examples of valid value formats are as follows: Binary string: '11010010111001'B Hex string: '0fa56920014abc'H Char string: 'abcdefg'

Parameters:

value - The ASN.1 value specification text

data - Array of bytes to compare string with.

stringEqualsBytes

public static boolean stringEqualsBytes(java.lang.String value,
                                        byte[] data,
                                        int nbits)
                                 throws Asn1ValueParseException

This static method parses the given ASN.1 value text (either a binary or hex data string) and compares it with the given byte array. This version of the method allows you to specify a number of bits to compare, which is useful when dealing with bit strings, as opposed to octet strings. Examples of valid value formats are as follows: Binary string: '11010010111001'B Hex string: '0fa56920014abc'H Char string: 'abcdefg'

Parameters:

value - The ASN.1 value specification text

data - Array of bytes to compare string with.

nbits - Number of bits in data to compare.

Throws:

Asn1ValueParseException

parseString

public static byte[] parseString(java.lang.String value,
                                 IntHolder numbits)
                          throws Asn1ValueParseException

This static method parses the given ASN.1 value text (either a binary or hex data string) and returns the value in a binary byte array. The number of bits is also returned. Examples of valid value formats are as follows: Binary string: '11010010111001'B Hex string: '0fa56920014abc'H Char string: 'abcdefg'

Parameters:

value - The ASN.1 value specification text

numbits - Holder to receive number of bits in string

Throws:

Asn1ValueParseException

parseString

public static byte[] parseString(java.lang.String value)
                          throws Asn1ValueParseException

This overloaded version of the parseString method sets the numbits holder value to null.

Parameters:

value - The ASN.1 value specification text

Throws:

Asn1ValueParseException
