Summary

mxStylesheetCodec	Codec for mxStylesheets.
Functions

getStringValue	Returns the string for encoding the given value.
decode	Reads a sequence of the following child nodes and attributes:
Variables
allowEval	Static global switch that specifies if the use of eval is allowed for evaluating text content.

Functions

encode

codec.encode = function( enc,
obj )

Encodes a stylesheet. See decode for a description of the format.

getStringValue

codec.getStringValue = function( key,
value )

Returns the string for encoding the given value.

decode

codec.decode = function( dec,
node,
into )

Reads a sequence of the following child nodes and attributes:

Child Nodes

add	Adds a new style.

Attributes

as	Name of the style.
extend	Name of the style to inherit from.

Each node contains another sequence of add and remove nodes with the following attributes:

as	Name of the style (see mxConstants).
value	Value for the style.

Instead of the value-attribute, one can put Javascript expressions into the node as follows if mxStylesheetCodec.allowEval is true: <add as=”perimeter”>mxPerimeter.RectanglePerimeter</add>

A remove node will remove the entry with the name given in the as-attribute from the style.

Example

<mxStylesheet as="stylesheet">
  <add as="text">
    <add as="fontSize" value="12"/>
  </add>
  <add as="defaultVertex" extend="text">
    <add as="shape" value="rectangle"/>
  </add>
</mxStylesheet>

Variables

allowEval

mxStylesheetCodec.allowEval

Static global switch that specifies if the use of eval is allowed for evaluating text content. Default is true. Set this to false if stylesheets may contain user input (see the section on security in the manual).
