| Method Summary | |
| public static boolean | checkVersion(Document doc, URL url)
Returnss whether the loaded document's version is correct. | | final public static void | dumpTree(Group group)
Print a readable tree of the specified group to System.out. | | final public static void | dumpTree(PrintStream s, Group group)
Print a readable tree of the specified group to the specified stream. | | final public static void | dumpTree(PrintWriter s, Group group)
Print a readable tree of the specified group to the specified writer. | | final public static Element | findElement(List elems, String name)
Returns the first element whose sub-element called "name" has the
same content as the name argument, or null if not found. | | public static void | format(Element e)
Formats the specified element for better readability by
adding white spaces. | | final public static Element | getFirstElement(Group group)
Returns the first child element, or null if no child element at all. | | final public static String | getRequiredAttributeValue(Element e, String attrnm)
Returns the required attribute value. | | final public static Element | getRequiredElement(Element e, String elemnm)
Returns the required element. | | final public static String | getRequiredElementValue(Element e, String elemnm)
Returns the required element value. | | final public static Map | parseParams(Element elm, String type, String name, String value)
Parses a tree of parameter elements into a map.
The tree of parameter elements is as follows.
<type>
<name>any</name>
<vaue>any</vaue>
</type>
the map after parsed (never null).
| | final public static void | setContents(Collection elems, Object val)
Set the contents of elements. | | final public static Object | toContents(Object obj)
Converts elements to their contents if the giving object is
an element or an array or a collection of elements. | | final public static String | toString(Document doc)
Transforms a document to a string. |
| checkVersion | | public static boolean checkVersion(Document doc, URL url) throws Exception(Code) | | Returnss whether the loaded document's version is correct.
It assumes the version info is specified in the document in
the following format:
<version>
<version-class>org.zkoss.zul.Version</version-class>
<version-uid>3.0.0</version-uid>
</version>
Note: it returns true if the version info is not found.
Parameters:
doc - the document to check
Parameters:
url - the URL used to show the readable message if theversion doesn't match
since:
3.0.0 |
| dumpTree | | final public static void dumpTree(Group group)(Code) | | Print a readable tree of the specified group to System.out.
It is for debug purpose and the generated format is not XML.
To generate XML, uses
Transformer or
IDOMs.toString .

| findElement | | final public static Element findElement(List elems, String name)(Code) | | Returns the first element whose sub-element called "name" has the
same content as the name argument, or null if not found.
Parameters:
elems - a list of elements to look for the specified name |
| format | | public static void format(Element e)(Code) | | Formats the specified element for better readability by
adding white spaces.
|
| getFirstElement | | final public static Element getFirstElement(Group group)(Code) | | Returns the first child element, or null if no child element at all.
|
| parseParams | | final public static Map parseParams(Element elm, String type, String name, String value)(Code) | | Parses a tree of parameter elements into a map.
The tree of parameter elements is as follows.
<type>
<name>any</name>
<vaue>any</vaue>
</type>
the map after parsed (never null). An empty map is returnedif no parameter is defined. The map is in the same order of the element tree.
|
| setContents | | final public static void setContents(Collection elems, Object val)(Code) | | Set the contents of elements.
The val argument could be an array and a collection, and each
item will be assigned to each of the list one-by-one.
Unlike
IDOMs.toContents , it handles only a collection of elements
-- all items must be elements.
Parameters:
elems - the collection of elements
Parameters:
val - the value which could be an object, an array or a collection |
| toContents | | final public static Object toContents(Object obj)(Code) | | Converts elements to their contents if the giving object is
