Typically, you'll only ever need to call on
render(), or one of the methods for setting/adding
filter, helper, and script paths. However, if you wish to extend
Zend_View yourself, or need access to some of its
internals, a number of accessors exist:
getVars()will return all assigned variables.
clearVars()will clear all assigned variables; useful when you wish to re-use a view object, but want to control what variables are available.
getScriptPath($script)will retrieve the resolved path to a given view script.
getScriptPaths()will retrieve all registered script paths.
getHelperPath($helper)will retrieve the resolved path to the named helper class.
getHelperPaths()will retrieve all registered helper paths.
getFilterPath($filter)will retrieve the resolved path to the named filter class.
getFilterPaths()will retrieve all registered filter paths.
