Method Detail

length

public int length()

Description copied from interface: ECIInput

Returns the length of this input. The length is the number of bytes in or ECIs in the sequence.

Specified by:

length in interface ECIInput

Returns:

the number of chars in this sequence

charAt

public char charAt(int index)

Description copied from interface: ECIInput

Returns the byte value at the specified index. An index ranges from zero to length() - 1. The first byte value of the sequence is at index zero, the next at index one, and so on, as for array indexing.

Specified by:

charAt in interface ECIInput

Parameters:

index - the index of the byte value to be returned

Returns:

the specified byte value as character or the FNC1 character

isECI

public boolean isECI(int index)

Description copied from interface: ECIInput

Determines if a value is an ECI

Specified by:

isECI in interface ECIInput

Parameters:

index - the index of the value

Returns:

true if the value at position index is an ECI

getECIValue

public int getECIValue(int index)

Description copied from interface: ECIInput

Returns the int ECI value at the specified index. An index ranges from zero to length() - 1. The first byte value of the sequence is at index zero, the next at index one, and so on, as for array indexing.

Specified by:

getECIValue in interface ECIInput

Parameters:

index - the index of the int value to be returned

Returns:

the specified int ECI value. The ECI specified the encoding of all bytes with a higher index until the next ECI or until the end of the input if no other ECI follows.

haveNCharacters

public boolean haveNCharacters(int index,
                               int n)

Specified by:

haveNCharacters in interface ECIInput

subSequence

public java.lang.CharSequence subSequence(int start,
                                          int end)

Description copied from interface: ECIInput

Returns a CharSequence that is a subsequence of this sequence. The subsequence starts with the char value at the specified index and ends with the char value at index end - 1. The length (in chars) of the returned sequence is end - start, so if start == end then an empty sequence is returned.

Specified by:

subSequence in interface ECIInput

Parameters:

start - the start index, inclusive

end - the end index, exclusive

Returns:

the specified subsequence

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
