- * TTemplateManager class
- *
- * TTemplateManager manages the loading and parsing of control templates.
- *
- * There are two ways of loading a template, either by the associated template
- * control class name, or the template file name.
- * The former is via calling {@link getTemplateByClassName}, which tries to
- * locate the corresponding template file under the directory containing
- * the class file. The name of the template file is the class name with
- * the extension '.tpl'. To load a template from a template file path,
- * call {@link getTemplateByFileName}.
- *
- * By default, TTemplateManager is registered with {@link TPageService} as the
- * template manager module that can be accessed via {@link TPageService::getTemplateManager()}.

-/**
- * TTemplate implements PRADO template parsing logic.
- * A TTemplate object represents a parsed PRADO control template.
- * It can instantiate the template as child controls of a specified control.
- * The template format is like HTML, with the following special tags introduced,
- * - component tags: a component tag represents the configuration of a component.
- * The tag name is in the format of com:ComponentType, where ComponentType is the component
- * class name. Component tags must be well-formed. Attributes of the component tag
- * are treated as either property initial values, event handler attachment, or regular
- * tag attributes.
- * - property tags: property tags are used to set large block of attribute values.
- * The property tag name is in the format of <prop:AttributeName> where AttributeName
- * can be a property name, an event name or a regular tag attribute name.
- * - group subproperty tags: subproperties of a common property can be configured using
- * <prop:MainProperty SubProperty1="Value1" SubProperty2="Value2" .../>
- * - directive: directive specifies the property values for the template owner.
- * It is in the format of <%@ property name-value pairs %>;
- * - expressions: They are in the format of <%= PHP expression %> and <%% PHP statements %>
- * - comments: There are two kinds of comments, regular HTML comments and special template comments.
- * The former is in the format of <!-- comments -->, which will be treated as text strings.
- * The latter is in the format of <!-- comments --!>, which will be stripped out.
- *
- * Tags other than the above are not required to be well-formed.
- *
- * A TTemplate object represents a parsed PRADO template. To instantiate the template
- * for a particular control, call {@link instantiateIn($control)}, which
- * will create and intialize all components specified in the template and
- * set their parent as $control.
