Constructors

RenderedLine(LexemParser, IParsePoint, ConfigStack)

Initializes a new instance of the RenderedLine class.

Declaration
public RenderedLine(LexemParser parser, IParsePoint pointLineStart, ConfigStack stack)
Parameters
Type Name Description
LexemParser parser

Parent parser.
IParsePoint pointLineStart

ParsePoint of the line start.
ConfigStack stack

Stack at the beginning of the line.

Properties

Changed

Gets a value indicating whether the line was changed after the last save.

Declaration
public bool Changed { get; }
Property Value
Type
System.Boolean

Height

Gets or sets height of the line.

Declaration
public float Height { get; set; }
Property Value
Type
System.Single

IsMeasured

Gets a value indicating whether the line was already measured.

Declaration
public bool IsMeasured { get; }
Property Value
Type
System.Boolean

LineLength

Gets the length of the line.

Declaration
public int LineLength { get; }
Property Value
Type
System.Int32

Parsed

Gets or sets a value indicating, whether line is parsed. If line is parsed, than LineEndStack property contains Stack for the end of the line and LineLexems collection contains all lexems, that belong to current line. If line was changed, than Parsed will be set to false.

Declaration
public override bool Parsed { get; set; }
Property Value
Type
System.Boolean
Overrides

SubLineHeight

Gets or sets the array of heights of the sublines. SubLines indexes start from 0.

Declaration
public float[] SubLineHeight { get; set; }
Property Value
Type
System.Single[]

SubLinesCount

Gets the count of sublines.

Declaration
public int SubLinesCount { get; }
Property Value
Type
System.Int32

Width

Gets the width of the line.

Declaration
public float Width { get; }
Property Value
Type
System.Single

Y

Gets or sets render position of line.

Declaration
public float Y { get; set; }
Property Value
Type
System.Single

Methods

Dispose()

Disposes all object.

Declaration
public override void Dispose()
Overrides

DropMeasureInfo()

Drops all information about measuring.

Declaration
public void DropMeasureInfo()

FindLexemByX(Single, Single)

Searches the lexem, that contains given x offset.

Declaration
public ILexem FindLexemByX(float x, float yOffset)
Parameters

System.Single y

Y offset of subline.
Returns
Type Description
IRenderedLexem

Last lexem in the subline with offset Y.
