mxCellState

Represents the current state of a cell in a given mxGraphView.

Summary

mxCellState	Represents the current state of a cell in a given mxGraphView.
Variables
view	Reference to the enclosing mxGraphView.
cell	Reference to the mxCell that is represented by this state.
style	Contains an array of key, value pairs that represent the style of the cell.
invalid	Specifies if the state is invalid.
origin	mxPoint that holds the origin for all child cells.
absolutePoints	Holds an array of mxPoints that represent the absolute points of an edge.
absoluteOffset	mxPoint that holds the absolute offset.
terminalDistance	Caches the distance between the end points for an edge.
length	Caches the length of an edge.
segments	Array of numbers that represent the cached length of each segment of the edge.
labelBounds	Holds the rectangle which contains the label.
boundingBox	Holds the largest rectangle which contains all rendering for this cell.
Functions
mxCellState	Constructs a new object that represents the current state of the given cell in the specified view.
getPerimeterBounds	Returns the mxRectangle that should be used as the perimeter of the cell.
copy	Returns a copy of this state where all members are deeply cloned except the view and cell references, which are copied with no cloning to the new instance.

Variables

view

var $view

Reference to the enclosing mxGraphView.

cell

var $cell

Reference to the mxCell that is represented by this state.

style

var $style

Contains an array of key, value pairs that represent the style of the cell.

invalid

var $invalid

Specifies if the state is invalid. Default is true.

origin

var $origin

mxPoint that holds the origin for all child cells. Default is a new empty mxPoint.

absolutePoints

var $absolutePoints

Holds an array of mxPoints that represent the absolute points of an edge.

absoluteOffset

var $absoluteOffset

mxPoint that holds the absolute offset. For edges, this is the absolute coordinates of the label position. For vertices, this is the offset of the label relative to the top, left corner of the vertex.

terminalDistance

var $terminalDistance

Caches the distance between the end points for an edge.

length

var $length

Caches the length of an edge.

segments

var $segments

Array of numbers that represent the cached length of each segment of the edge.

labelBounds

var $labelBounds

Holds the rectangle which contains the label.

boundingBox

var $boundingBox

Holds the largest rectangle which contains all rendering for this cell.

Functions

mxCellState

function mxCellState( $view = null,
$cell = null,
$style = null )

Constructs a new object that represents the current state of the given cell in the specified view.

Parameters

view	mxGraphView that contains the state.
cell	mxCell that this state represents.
style	Array of key, value pairs that constitute the style.

getPerimeterBounds

function getPerimeterBounds( $border = 0 )

Returns the mxRectangle that should be used as the perimeter of the cell.

copy

function copy()

Returns a copy of this state where all members are deeply cloned except the view and cell references, which are copied with no cloning to the new instance.
