Required Methods§
Sourcefn length(&self) -> usize
fn length(&self) -> usize
Returns the length of this input. The length is the number of {@code byte}s in or ECIs in the sequence.
@return the number of {@code char}s in this sequence
Sourcefn charAt(&self, index: usize) -> Result<char>
fn charAt(&self, index: usize) -> Result<char>
Returns the {@code byte} value at the specified index. An index ranges from zero to {@code length() - 1}. The first {@code byte} value of the sequence is at index zero, the next at index one, and so on, as for array indexing.
@param index the index of the {@code byte} value to be returned
@return the specified {@code byte} value as character or the FNC1 character
@throws IndexOutOfBoundsException if the {@code index} argument is negative or not less than {@code length()} @throws IllegalArgumentException if the value at the {@code index} argument is an ECI (@see #isECI)
Sourcefn subSequence(&self, start: usize, end: usize) -> Result<Vec<char>>
fn subSequence(&self, start: usize, end: usize) -> Result<Vec<char>>
Returns a {@code CharSequence} that is a subsequence of this sequence. The subsequence starts with the {@code char} value at the specified index and ends with the {@code char} value at index {@code end - 1}. The length (in {@code char}s) of the returned sequence is {@code end - start}, so if {@code start == end} then an empty sequence is returned.
@param start the start index, inclusive @param end the end index, exclusive
@return the specified subsequence
@throws IndexOutOfBoundsException if {@code start} or {@code end} are negative, if {@code end} is greater than {@code length()}, or if {@code start} is greater than {@code end} @throws IllegalArgumentException if a value in the range {@code start}-{@code end} is an ECI (@see #isECI)
Sourcefn isECI(&self, index: u32) -> Result<bool>
fn isECI(&self, index: u32) -> Result<bool>
Determines if a value is an ECI
@param index the index of the value
@return true if the value at position {@code index} is an ECI
@throws IndexOutOfBoundsException if the {@code index} argument is negative or not less than {@code length()}
Sourcefn getECIValue(&self, index: usize) -> Result<Eci>
fn getECIValue(&self, index: usize) -> Result<Eci>
Returns the {@code int} ECI value at the specified index. An index ranges from zero to {@code length() - 1}. The first {@code byte} value of the sequence is at index zero, the next at index one, and so on, as for array indexing.
@param index the index of the {@code int} value to be returned
@return the specified {@code 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.
@throws IndexOutOfBoundsException if the {@code index} argument is negative or not less than {@code length()} @throws IllegalArgumentException if the value at the {@code index} argument is not an ECI (@see #isECI)
