browser detection code
cross ported from dojo 1.2
dojos browser detection code is very sophisticated
hence we port it over it allows a very fine grained detection of
browsers including the version number
this however only can work out if the user
does not alter the user agent, which they normally dont!
the exception is the ie detection which relies on specific quirks in ie

|---|---|
| <static> |
myfaces._impl.core._Runtime.addOnLoad(func, func)
onload wrapper for chaining the onload cleanly
|
| <static> |
myfaces._impl.core._Runtime.applyToGlobalNamespace(nms, obj)
applies an object to a namespace
basically does what bla.my.name.space = obj does
note we cannot use var myNameSpace = fetchNamespace("my.name.space")
myNameSpace = obj because the result of fetch is already the object
which the namespace points to, hence this function
|
| <static> |
myfaces._impl.core._Runtime.assertType(probe, theType)
general type assertion routine
|
| <static> |
myfaces._impl.core._Runtime.exists(root, subNms)
check if an element exists in the root
also allows to check for subelements
usage
_T.exists(rootElem,"my.name.space")
|
| <static> |
myfaces._impl.core._Runtime.fetchNamespace(nms)
fetches the object the namespace points to
|
| <static> |
myfaces._impl.core._Runtime.getGlobalConfig(configName, defaultValue)
fetches a global config entry
|
| <static> |
myfaces._impl.core._Runtime.getLanguage(lOverride)
returns the internationalisation setting
for the given browser so that
we can i18n our messages
|
| <static> |
myfaces._impl.core._Runtime.getLocalOrGlobalConfig(configName, localOptions, defaultValue)
gets the local or global options with local ones having higher priority
if no local or global one was found then the default value is given back
|
| <static> |
myfaces._impl.core._Runtime.getXHRLvl()
determines the xhr level which either can be
1 for classical level1
1.5 for mozillas send as binary implementation
2 for xhr level 2
|
| <static> |
myfaces._impl.core._Runtime.getXHRObject()
encapsulated xhr object which tracks down various implementations
of the xhr object in a browser independent fashion
(ie pre 7 used to have non standard implementations because
the xhr object standard came after IE had implemented it first
newer ie versions adhere to the standard and all other new browsers do anyway)
|
| <static> |
myfaces._impl.core._Runtime.globalEval(code)
global eval on scripts
|
| <static> |
myfaces._impl.core._Runtime.isString(it)
Backported from dojo
a failsafe string determination method

iterates over all registered singletons in the namespace
|
| <static> |
myfaces._impl.core._Runtime.iterateSingletons(operator)
iterates over all registered singletons in the namespace

myfaces._impl.core._Runtime.loadScriptByBrowser(src, type, defer, charSet, async)
load script functionality which utilizes the browser internal
script loading capabilities

| <static> |
myfaces._impl.core._Runtime.loadScriptEval(src, type, defer, charSet, async)
loads a script and executes it under a global scope
|
| <static> |
myfaces._impl.core._Runtime.reserveNamespace(nms, obj)
reserves a namespace in the specific scope
usage:
if(_T.reserve("org.apache.myfaces.MyUtils")) {
org.apache.myfaces.MyUtils = function() {
}
}
reserves a namespace and if the namespace is new the function itself is reserved

Method Detail
<static>
myfaces._impl.core._Runtime.addOnLoad(func, func)
onload wrapper for chaining the onload cleanly
- Parameters:
- func
- the function which should be added to the load chain (note we cannot rely on return values here, hence jsf.util.chain will fail)
- func
<static>
myfaces._impl.core._Runtime.applyToGlobalNamespace(nms, obj)
applies an object to a namespace
basically does what bla.my.name.space = obj does
note we cannot use var myNameSpace = fetchNamespace("my.name.space")
myNameSpace = obj because the result of fetch is already the object
which the namespace points to, hence this function
- Parameters:
- {String} nms
- the namespace to be assigned to
- {Object} obj
- the object to be assigned
<static>
myfaces._impl.core._Runtime.assertType(probe, theType)
general type assertion routine
- Parameters:
- probe
- the probe to be checked for the correct type
- theType
- the type to be checked for
<static>
myfaces._impl.core._Runtime.exists(root, subNms)
check if an element exists in the root
also allows to check for subelements
usage
_T.exists(rootElem,"my.name.space")
- Parameters:
- {Object} root
- the root element
- {String} subNms
- the namespace
<static>
myfaces._impl.core._Runtime.fetchNamespace(nms)
fetches the object the namespace points to
- Parameters:
- {String} nms

- the object the namespace points to or null if nothing is found
<static>
myfaces._impl.core._Runtime.getGlobalConfig(configName, defaultValue)
fetches a global config entry
- Parameters:
- {String} configName
- the name of the configuration entry

- either the config entry or if none is given the default value
<static>
myfaces._impl.core._Runtime.getLanguage(lOverride)
returns the internationalisation setting
for the given browser so that
we can i18n our messages
- Parameters:

- language: the lowercase language iso code
- variant: the uppercase variant iso code
<static>
myfaces._impl.core._Runtime.getLocalOrGlobalConfig(configName, localOptions, defaultValue)
gets the local or global options with local ones having higher priority

- Parameters:
- {String} configName
- the name of the configuration entry
- {String} localOptions
- the local options root for the configuration myfaces as default marker is added implicitely
- {Object} defaultValue
- Returns:

myfaces._impl.core._Runtime.loadScriptByBrowser(src, type, defer, charSet, async)
load script functionality which utilizes the browser internal
script loading capabilities

<static>
myfaces._impl.core._Runtime.loadScriptEval(src, type, defer, charSet, async)
loads a script and executes it under a global scope

<static>
{boolean}
myfaces._impl.core._Runtime.reserveNamespace(nms, obj)
reserves a namespace in the specific scope
usage:
if(_T.reserve("org.apache.myfaces.MyUtils")) {
org.apache.myfaces.MyUtils = function() {
}
}
reserves a namespace and if the namespace is new the function itself is reserved
or:
_T.reserve("org.apache.myfaces.MyUtils", function() { .. });
reserves a namespace and if not already registered directly applies the function the namespace
note for now the reserved namespaces reside as global maps justl like jsf.js but
we also use a speedup index which is kept internally to reduce the number of evals or loops to walk through those
namespaces (eval is a heavy operation and loops even only for namespace resolution introduce (O)2 runtime
complexity while a simple map lookup is (O)log n with additional speedup from the engine.
- Parameters:
- {String} nms
- obj
- Returns:
- {boolean} true if it was not provided false otherwise for further action
<static>
myfaces._impl.core._Runtime.singletonExtendClass(newCls, extendsCls, protoFuncs, nmsFuncs)
Extends a class and puts a singleton instance at the reserved namespace instead
of its original class
- Parameters:
- {function|String} newCls
- either a unnamed function which can be assigned later or a namespace
- {function} extendsCls
- the function class to be extended
- {Object} protoFuncs
- (Map) an optional map of prototype functions which in case of overwriting a base function get an inherited method
- nmsFuncs
