Call the original method that was previously overridden with override

\n\n
Ext.define('My.Cat', {\n    constructor: function() {\n        alert(\"I'm a cat!\");\n    }\n});\n\nMy.Cat.override({\n    constructor: function() {\n        alert(\"I'm going to be a cat!\");\n\n        this.callOverridden();\n\n        alert(\"Meeeeoooowwww\");\n    }\n});\n\nvar kitty = new My.Cat(); // alerts \"I'm going to be a cat!\"\n                          // alerts \"I'm a cat!\"\n                          // alerts \"Meeeeoooowwww\"\n
\n
\n

This method has been deprecated

\n

as of 4.1. Use callParent instead.

\n\n
\n

Parameters

  • args : Array/Arguments

    The arguments, either an array or the arguments object\nfrom the current method, for example: this.callOverridden(arguments)

    \n

Returns

  • Object

    Returns the result of calling the overridden method

    \n
Ext.Base
view source
( Array/Arguments args ) : Objectprotected
Call the \"parent\" method of the current method. ...

Call the \"parent\" method of the current method. That is the method previously\noverridden by derivation or by an override (see Ext.define).

\n\n
 Ext.define('My.Base', {\n     constructor: function (x) {\n         this.x = x;\n     },\n\n     statics: {\n         method: function (x) {\n             return x;\n         }\n     }\n });\n\n Ext.define('My.Derived', {\n     extend: 'My.Base',\n\n     constructor: function () {\n         this.callParent([21]);\n     }\n });\n\n var obj = new My.Derived();\n\n alert(obj.x);  // alerts 21\n
\n\n

This can be used with an override as follows:

\n\n
 Ext.define('My.DerivedOverride', {\n     override: 'My.Derived',\n\n     constructor: function (x) {\n         this.callParent([x*2]); // calls original My.Derived constructor\n     }\n });\n\n var obj = new My.Derived();\n\n alert(obj.x);  // now alerts 42\n
\n\n

This also works with static methods.

\n\n
 Ext.define('My.Derived2', {\n     extend: 'My.Base',\n\n     statics: {\n         method: function (x) {\n             return this.callParent([x*2]); // calls My.Base.method\n         }\n     }\n });\n\n alert(My.Base.method(10);     // alerts 10\n alert(My.Derived2.method(10); // alerts 20\n
\n\n

Lastly, it also works with overridden static methods.

\n\n
 Ext.define('My.Derived2Override', {\n     override: 'My.Derived2',\n\n     statics: {\n         method: function (x) {\n             return this.callParent([x*2]); // calls My.Derived2.method\n         }\n     }\n });\n\n alert(My.Derived2.method(10); // now alerts 40\n
\n

Parameters

  • args : Array/Arguments

    The arguments, either an array or the arguments object\nfrom the current method, for example: this.callParent(arguments)

    \n

Returns

  • Object

    Returns the result of calling the parent method

( Number prevX, Number prevY, Number curX, Number curY, Number nextX, Number nextY, Number value ) : Objectprivate
Calculates bezier curve control anchor points for a particular point in a path, with a\nsmoothing curve applied. ...

Calculates bezier curve control anchor points for a particular point in a path, with a\nsmoothing curve applied. The smoothness of the curve is controlled by the 'value' parameter.\nNote that this algorithm assumes that the line being smoothed is normalized going from left\nto right; it makes special adjustments assuming this orientation.

\n

Parameters

  • prevX : Number

    X coordinate of the previous point in the path

    \n
  • prevY : Number

    Y coordinate of the previous point in the path

    \n
  • curX : Number

    X coordinate of the current point in the path

    \n
  • curY : Number

    Y coordinate of the current point in the path

    \n
  • nextX : Number

    X coordinate of the next point in the path

    \n
  • nextY : Number

    Y coordinate of the next point in the path

    \n
  • value : Number

    A value to control the smoothness of the curve; this is used to

    \n\n
                divide the distance between points, so a value of 2 corresponds to\n            half the distance between points (a very smooth line) while higher values\n            result in less smooth curves. Defaults to 4.\n
    \n

Returns

  • Object

    Object containing x1, y1, x2, y2 bezier control anchor points; x1 and y1

    \n\n
                 are the control point for the curve toward the previous path point, and\n             x2 and y2 are the control point for the curve toward the next path point.\n

snapEndsByDate is a utility method to deduce an appropriate tick configuration for the data set of given\nfeature. ...

snapEndsByDate is a utility method to deduce an appropriate tick configuration for the data set of given\nfeature. Refer to snapEnds.

\n

Parameters

  • from : Date

    The minimum value in the data

    \n
  • to : Date

    The maximum value in the data

    \n
  • stepsMax : Number

    The maximum number of ticks

    \n
  • lockEnds : Boolean

    If true, the 'from' and 'to' parameters will be used as fixed end values

    \n\n
       and will not be adjusted\n
    \n

Returns

  • Object

    The calculated step and ends info; properties are:

    \n\n
    - from: The result start value, which may be lower than the original start value\n- to: The result end value, which may be higher than the original end value\n- step: The value size of each step\n- steps: The number of steps. NOTE: the steps may not divide the from/to range perfectly evenly;\n         there may be a smaller distance between the last step and the end value than between prior\n         steps, particularly when the `endsLocked` param is true. Therefore it is best to not use\n         the `steps` result when finding the axis tick points, instead use the `step`, `to`, and\n         `from` to find the correct point for each tick.\n
