Method Details

getCodePoint

public int getCodePoint()

Returns the code point that occurs in the associated CharacterInput at this CharacterInput.CodePointPosition.

Returns:

The unicode code point at this CharacterInput.CodePointPosition.

getLineNumber

public int getLineNumber()

Computes the line number that corresponds to this CharacterInput.CodePointPosition as it is perceived by the user. That is to say, this is not necessarily the character offset in this CharacterInput.CodePointPosition but the unicode code point offset.

Returns:

The line number of this CharacterInput.CodePointPosition.

getColumnNumber

public int getColumnNumber()

Computes the column number that corresponds to this CharacterInput.CodePointPosition as it is perceived by the user. That is to say, this is not necessarily the character offset in this CharacterInput.CodePointPosition but the unicode code point offset relative to the corresponding line offset.

Returns:

The column number of this CharacterInput.CodePointPosition.

describe

public String describe()

Description copied from class: Input.Position

Describes the element to which this Input<T>.Position refers to.

Specified by:

describe in class Input<Character>.Position

Returns:

A String representation of the element to which this Input<T>.Position refers to.

toString

public String toString()

Specified by:

toString in class Input<Character>.Position
