Constructor Detail

Asn1DiscreteCharSet

public Asn1DiscreteCharSet(java.lang.String charSet)

This constructor sets the permitted alphabet chracter set

Parameters:

charSet - Permitted alphabet character set

Asn1DiscreteCharSet

public Asn1DiscreteCharSet(int[] charSet)

This constructor sets the permitted alphabet chracter set

Parameters:

charSet - Permitted alphabet character set

Method Detail

getCharAtIndex

public int getCharAtIndex(int index)
                   throws Asn1ConsVioException

This method will fetch the character from the permitted alphabet at the given index.

Specified by:

getCharAtIndex in class Asn1CharSet

Parameters:

index - Index of character within the character set

Returns:

Character at given index

Throws:

Asn1ConsVioException - Index not within define range

getCharIndex

public int getCharIndex(int charValue)
                 throws Asn1ConsVioException

This method will determine the index of the given character within the permitted alphabet character set.

Specified by:

getCharIndex in class Asn1CharSet

Parameters:

charValue - Character value to search for

Returns:

Index of character

Throws:

Asn1ConsVioException - Character not found in set

getMaxValue

public int getMaxValue()

This method will determine the maximum value of the given character within the permitted alphabet character set. As the charset is canonical order, max value is of the last character.

Specified by:

getMaxValue in class Asn1CharSet

Returns:

Upper Bound Character or Character with max int value

validate

public boolean validate(java.lang.String s)

This method will validate a character string by comparing its contents to the character set. If a character string contains characters that are not in the character set, this method will return false. Otherwise it returns true.

Specified by:

validate in class Asn1CharSet

Parameters:

s - The string to be validated.

Returns:

False if the string contains invalid characters; true otherwise.

helpValidate

protected boolean helpValidate(char c)

This function helps validate a character string by checking a character to see if it is in the character set. It returns false if a character is not contained in the set and true otherwise.
