Ext.BaseExt.XTemplateParserExt.XTemplateCompilerFiles
NOTE This is a private utility class for internal use by the framework. Don't rely on its existence.
This class compiles the XTemplate syntax into a function object. The function is used\nlike so:
\n\n function (out, values, parent, xindex, xcount) {\n // out is the output array to store results\n // values, parent, xindex and xcount have their historical meaning\n }\n
\nDefaults to: /\\s*(elif|elseif|if|for|foreach|exec|switch|case|eval|between)\\s*\\=\\s*(?:(?:"([^"]*)")|(?:'([^']*)'))\\s*/g
Get the reference to the current class from which this object was instantiated. Unlike statics,\nthis.self
is scope-dependent and it's meant to be used for dynamic inheritance. See statics\nfor a detailed comparison
Ext.define('My.Cat', {\n statics: {\n speciesName: 'Cat' // My.Cat.speciesName = 'Cat'\n },\n\n constructor: function() {\n alert(this.self.speciesName); // dependent on 'this'\n },\n\n clone: function() {\n return new this.self();\n }\n});\n\n\nExt.define('My.SnowLeopard', {\n extend: 'My.Cat',\n statics: {\n speciesName: 'Snow Leopard' // My.SnowLeopard.speciesName = 'Snow Leopard'\n }\n});\n\nvar cat = new My.Cat(); // alerts 'Cat'\nvar snowLeopard = new My.SnowLeopard(); // alerts 'Snow Leopard'\n\nvar clone = snowLeopard.clone();\nalert(Ext.getClassName(clone)); // alerts 'My.SnowLeopard'\n
\nDefaults to: /^([\\w-\\.\\#\\$]+)(?:\\:([\\w\\.]*)(?:\\((.*?)?\\))?)?(\\s?[\\+\\-\\*\\/]\\s?[\\d\\.\\+\\-\\*\\/\\(\\)]+)?$/
Internal regexes
\nDefaults to: /(?:(\\{\\%)|(\\{\\[)|\\{([^{}]+)\\})|(?:<tpl([^>]*)\\>)|(?:<\\/tpl>)/g
Chrome really likes \"new Function\" to realize the code block (as in it is\n2x-3x faster to call it than using eval), but Firefox chokes on it badly.\nIE and Opera are also fine with the \"new Function\" technique.
\nSee http://jsperf.com/nige-array-append for quickest way to append to an array of unknown length\n(Due to arbitrary code execution inside a template, we cannot easily track the length in var)\nOn IE6 to 8, myArray[myArray.length]='foo' is better. On other browsers myArray.push('foo') is better.
\nCall the original method that was previously overridden with override
\n\nExt.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 This method has been deprecated
\nas of 4.1. Use callParent instead.
\n\nThe arguments, either an array or the arguments
object\nfrom the current method, for example: this.callOverridden(arguments)
Returns the result of calling the overridden method
\nCall 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\nThis 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\nThis 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\nLastly, 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\nTo override a method and replace it and also call the superclass method, use\ncallSuper. This is often done to patch a method to fix a bug.
\nThe arguments, either an array or the arguments
object\nfrom the current method, for example: this.callParent(arguments)
Returns the result of calling the parent method
\nThis method is used by an override to call the superclass method but bypass any\noverridden method. This is often done to \"patch\" a method that contains a bug\nbut for whatever reason cannot be fixed directly.
\n\nConsider:
\n\n Ext.define('Ext.some.Class', {\n method: function () {\n console.log('Good');\n }\n });\n\n Ext.define('Ext.some.DerivedClass', {\n method: function () {\n console.log('Bad');\n\n // ... logic but with a bug ...\n\n this.callParent();\n }\n });\n
\n\nTo patch the bug in DerivedClass.method
, the typical solution is to create an\noverride:
Ext.define('App.paches.DerivedClass', {\n override: 'Ext.some.DerivedClass',\n\n method: function () {\n console.log('Fixed');\n\n // ... logic but with bug fixed ...\n\n this.callSuper();\n }\n });\n
\n\nThe patch method cannot use callParent
to call the superclass method
since\nthat would call the overridden method containing the bug. In other words, the\nabove patch would only produce \"Fixed\" then \"Good\" in the console log, whereas,\nusing callParent
would produce \"Fixed\" then \"Bad\" then \"Good\".
The arguments, either an array or the arguments
object\nfrom the current method, for example: this.callSuper(arguments)
Returns the result of calling the superclass method

\nclassName
\nAdds members to class.
\nThis method has been deprecated since 4.1
\nUse addMembers instead.
\n\nOverride members of this class. Overridden methods can be invoked via\ncallParent.
\n\nExt.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.callParent(arguments);\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\nAs of 4.1, direct use of this method is deprecated. Use Ext.define\ninstead:
\n\nExt.define('My.CatOverride', {\n override: 'My.Cat',\n constructor: function() {\n alert(\"I'm going to be a cat!\");\n\n this.callParent(arguments);\n\n alert(\"Meeeeoooowwww\");\n }\n});\n
\n\nThe above accomplishes the same result but can be managed by the Ext.Loader\nwhich can properly order the override and its target class and the build process\ncan determine whether the override is needed based on the required state of the\ntarget class (My.Cat).
\nThis method has been deprecated since 4.1.0
\nUse Ext.define instead
\n\nThe properties to add to this class. This should be\nspecified as an object literal containing one or more properties.
