Syntax

public class UncachedLexemLine : ILexemLine, IDisposable, IComparable

Constructors

UncachedLexemLine(LexemParser, IParsePoint, ConfigStack)

Initializes a new instance of the UncachedLexemLine class.

Declaration

public UncachedLexemLine(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.

Fields

m_parser

Parser, the line belongs to.

Declaration

protected LexemParser m_parser

Field Value

Type
LexemParser

Properties

IsValid

Gets a value indicating whether the line is valid or not. If line was already disposed, it is no longer valid.

Declaration

public bool IsValid { get; }

Property Value

Type
System.Boolean

LineEndPoint

Gets the parse point at the end of the line.

Declaration

public virtual IParsePoint LineEndPoint { get; }

Property Value

Type
IParsePoint

LineEndStack

Gets the stack at the end of the line. If line was not parsed, it will be reparsed.

Declaration

public ConfigStack LineEndStack { get; }

Property Value

Type
ConfigStack

LineIndex

Gets or sets the index of the line.

Declaration

public int LineIndex { get; set; }

Property Value

Type
System.Int32

Remarks

It can be different from the one, stored in m_point because it also includes data from collapsing.

LineLength

Gets the length of the line.

Declaration

public int LineLength { get; }

Property Value

Type
System.Int32

LineLexems

Gets the collection of all lexems, that belong to current line. If line was not parsed, it will be reparsed.

Declaration

public IList LineLexems { get; }

Property Value

Type
System.Collections.IList

LineStartPoint

Gets the parse point at the beginning of the line.

Declaration

public IParsePoint LineStartPoint { get; }

Property Value

Type
IParsePoint

LineStartStack

Gets the stack at the beginning of the line.

Declaration

public ConfigStack LineStartStack { get; }

Property Value

Type
ConfigStack

Parsed

Gets a value indicating whether the line is parsed or not. 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 virtual bool Parsed { get; set; }

Property Value

Type
System.Boolean

Parser

Gets the parser, that the line belongs to.

Declaration

public ILexemParser Parser { get; }

Property Value

Type
ILexemParser

Methods

CompareTo(Object)

Compares two ILexemLine objects, or ILexemLine object and integer line number.

Declaration

public int CompareTo(object obj)

Parameters

Type	Name	Description
System.Object	obj	ILexemLine object or integer line number.

Returns

Type	Description
System.Int32	Standart comparision result.

DeleteSelf()

Raises LineDeleted event and disposes line.

Declaration

public void DeleteSelf()

Dispose()

Disposes all used resources.

Declaration

public virtual void Dispose()

FindLexemByColumn(Int32)

Searches the lexem, that contains given column index.

Declaration

public virtual ILexem FindLexemByColumn(int column)

Parameters

Type	Name	Description
System.Int32	column	Needed column.

Returns

Type	Description
ILexem	Found lexem, or null if needed column is in virtual space.

GetLineEndStack()

Gets stack at the end of line. Line will be reparsed.

Declaration

protected virtual ConfigStack GetLineEndStack()

Returns

Type	Description
ConfigStack	Stack at the end of line. It can be treated as start stack for the next line.

GetLineLexems(out Int64)

Collection of all lexems, that belongs to the line. Line will be reparsed.

Declaration

protected virtual IList GetLineLexems(out long lPositionBeforeNewLine)

Parameters

Type	Name	Description
System.Int64	lPositionBeforeNewLine

Returns

Type	Description
System.Collections.IList	List of the lexems.

GetStackByColumn(Int32)

Parameters

Type	Name	Description
System.Int32	column	Needed column.

Returns

Type	Description
ConfigStack	Copy of the stack.

PointPositionChanged(Object, ParsePointParameterChangedEventArgs)

Handler of the ParsePointOffsetChanged event of the stream.

Declaration

protected virtual void PointPositionChanged(object sender, ParsePointParameterChangedEventArgs e)

Parameters

Type	Name	Description
System.Object	sender	Changed ParsePoint.
ParsePointParameterChangedEventArgs	e	Change.

RaiseLineIndexChangedEvent()

Raises LineIndexChanged event.

Declaration

protected void RaiseLineIndexChangedEvent()

Events

LineDeleted

Occurs when line is deleted. If position of the LineStartPoint is changed, than line is considered to be invalid and must be deleted or LineStartPoint was deleted.

Declaration

public event EventHandler LineDeleted

Event Type

Type
System.EventHandler
