Syntax

public class Location : ICloneable

Remarks

The parent in the top level location (index 0) is the root container (often IParagraph or ISegment). The BottomLevel is the location in the lowest level.

Constructors

Location()

Default constructor

Declaration

public Location()

Location(IAbstractMarkupDataContainer, IAbstractMarkupData)

Creates a location that corresponds to the position of the item with regards to the specified root container.

Declaration

public Location(IAbstractMarkupDataContainer rootContainer, IAbstractMarkupData itemAtLocation)

Parameters

Type	Name	Description
IAbstractMarkupDataContainer	rootContainer	Must not be null
IAbstractMarkupData	itemAtLocation	Must be an item somewhere inside the root container, i.e. the root container must be an ancestor to the item.

Location(IAbstractMarkupDataContainer, Boolean)

Initialize the location to the first or last position in the specified root container.

Declaration

public Location(IAbstractMarkupDataContainer rootContainer, bool firstLocation)

Parameters

Type	Name	Description
IAbstractMarkupDataContainer	rootContainer
System.Boolean	firstLocation	Indicates whether the location should be initialized to the first or the last available location of the root container. Pass true to initialize it to the first location, and false to initialize it to the last location.

Location(LevelLocation)

Initializes the location with one level only. This generates a location that is equivalent to the passed-in LevelLocation.

Declaration

public Location(LevelLocation location)

Parameters

Type	Name	Description
LevelLocation	location	must not be null

Location(Location)

Creates a deep clone

Declaration

public Location(Location other)

Parameters

Type	Name	Description
Location	other

Properties

BottomLevel

Quick access to the most specific level

Declaration

public LevelLocation BottomLevel { get; }

Property Value

Type	Description
LevelLocation

Depth

Returns the number of levels in the location.

Declaration

public int Depth { get; }

Property Value

Type	Description
System.Int32

IsAtEnd

True if the MoveNext() method returns false.

Declaration

public bool IsAtEnd { get; }

Property Value

Type	Description
System.Boolean

IsAtStart

True if the MovePrevious() method returns false.

Declaration

public bool IsAtStart { get; }

Property Value

Type	Description
System.Boolean

IsValid

True if all levels are valid locations and each level corresponds to the location defined in the parent layer.

Declaration

public bool IsValid { get; }

Property Value

Type	Description
System.Boolean

ItemAtLocation

Returns the item at the location specified by the bottom level.

If the location is not valid, or if there is not item at the location (i.e. if it is a location after the last element in a collection), this property returns null.

Declaration

public IAbstractMarkupData ItemAtLocation { get; }

Property Value

Type	Description
IAbstractMarkupData

Levels

Provides access to the actual collection of levels that this location represents.

Declaration

public List<LevelLocation> Levels { get; }

Property Value

Type	Description
System.Collections.Generic.List<LevelLocation>

Methods

Clone()

Creates a deep clone of this object.

Declaration

public object Clone()

Returns

Type	Description
System.Object

Equals(Object)

Returns true if this location refers to the same position as the other location.

Declaration

public override bool Equals(object obj)

Parameters

Type	Name	Description
System.Object	obj

Returns

Type	Description
System.Boolean

Overrides

System.Object.Equals(System.Object)

GetHashCode()

Returns the hash code of the levels in this location.

Declaration

public override int GetHashCode()

Returns

Type	Description
System.Int32

Overrides

System.Object.GetHashCode()

MoveFirstChild()

Changes the location to refer to the position just before the first child node of the item at the current location.

If no child node is available (i.e. the current location does not refer to a node that is an IAbstractMarkupDataContainer), the location is not changed, and this method returns false.

Note that if the item at the current location is a container, but it has no content, the location is still advanced to a location at the index 0 inside the collection, as it is possible to insert new content there.

Declaration

public bool MoveFirstChild()

Returns

Type	Description
System.Boolean	True if the location was changed successfully

MoveLastChild()

Changes the location to just behind the last child node of the item at the current location.

If no child node is available (i.e. the current location does not refer to a node that is an IAbstractMarkupDataContainer), the location is not changed, and this method returns false.

Note that if the item at the current location is a container, but it has no content, the location is still advanced to a location at the index 0 inside the collection, as it is possible to insert new content there.

Declaration

public bool MoveLastChild()

Returns

Type	Description
System.Boolean	True if the location was changed successfully

MoveNext()

Advances to the next possible location. This will move to the next available position according to the following priority list:

If no such location is available (i.e. the location is currently behind the last item in the top level), the location is not changed, and the method returns false.

If the location is invalid, the behavior is undefined and exceptions may be thrown.

Declaration

public bool MoveNext()

Returns

Type	Description
System.Boolean	True if location was successfully advanced to the next possible position.

MoveNextSibling()

Advance the location to the next sibling position in the current bottom layer.

If no next sibling position is available (i.e. the location is already behind the last item in the parent collection), the location is not changed, and this method returns false.

Declaration

public bool MoveNextSibling()

Returns

Type	Description
System.Boolean	True if the location was changed successfully

MoveParent()

Changes the location to refer to the position just before the parent of the current bottom level location.

If no parent location is available (i.e. the location is already in the top layer), the location is not changed, and this method returns false.

Declaration

public bool MoveParent()

Returns

Type	Description
System.Boolean	True if the location was changed successfully

MovePrevious()

Moves the location to the preceding available position according to the following priority list:

If no parent is available (i.e. location is before the first item in the top level), the location is not changed, and the method returns false.

Declaration

public bool MovePrevious()

Returns

Type	Description
System.Boolean	True if the location was successfully moved to a previous position.

MovePreviousSibling()

Moves the location to the preceding sibling position in the current bottom layer.

If no previous sibling location is available (i.e. the current location is already at the start of the parent collection), the location is not changed, and this method returns false.

Declaration

public bool MovePreviousSibling()

Returns

Type	Description
System.Boolean	True if the location was changed successfully

ToString()

Overridden to provide more useful information while debugging

Declaration

public override string ToString()

Returns

Type	Description
System.String

Overrides

System.Object.ToString()
