All Implemented Interfaces:
java.io.Serializable, java.lang.Cloneable, Component, DynamicPropertied, DynamicTag, Native, NonFellow, Scope, ComponentCtrl

public class XmlNativeComponent
extends AbstractComponent
implements DynamicTag, Native

A comonent used to represent XML elements that are associated with the inline namespace (http://www.zkoss.org/2005/zk/inline).

It contains the content that shall be sent directly to client. It has three parts: prolog, children and epilog. The prolog (getPrologContent()) and epilog (getEpilogContent()) are both String.

When this component is renderred (redraw(java.io.Writer)), it generates the prolog first, the children and then the epilog.

3.0.0

Constructor Detail

XmlNativeComponent

public XmlNativeComponent()

XmlNativeComponent

public XmlNativeComponent(java.lang.String tag)
Method Detail

getTag

public java.lang.String getTag()
Returns the tag name, or null if plain text.


getDeclaredNamespaces

public java.util.List<Namespace> getDeclaredNamespaces()
Description copied from interface: Native
Returns a readonly list of the declared namespaces (Namespace), or empty if no declared namespace.

Specified by:
getDeclaredNamespaces in interface Native

addDeclaredNamespace

public void addDeclaredNamespace(Namespace ns)
Description copied from interface: Native
Adds a declared namespace. The added declared namespace will be generated to the output.

Specified by:
addDeclaredNamespace in interface Native
Parameters:
ns - the namespace (never null).

getPrologContent

public java.lang.String getPrologContent()
Description copied from interface: Native
Returns the prolog content. It is the content generated before the child components, if any.

Default: empty ("").

Specified by:
getPrologContent in interface Native

setPrologContent

public void setPrologContent(java.lang.String prolog)
Description copied from interface: Native
Sets the prolog content. It is the content generated before the child components, if any.

Specified by:
setPrologContent in interface Native

getEpilogContent

public java.lang.String getEpilogContent()
Description copied from interface: Native
Returns the epilog content. It is the content generated before the child components, if any.

Default: empty ("").

Specified by:
getEpilogContent in interface Native

setEpilogContent

public void setEpilogContent(java.lang.String epilog)
Description copied from interface: Native
Sets the epilog content. It is the content generated before the child components, if any.

Specified by:
setEpilogContent in interface Native

getHelper

public Native.Helper getHelper()
Description copied from interface: Native
Returns the helper to generate the output of the native components.

Specified by:
getHelper in interface Native

setId

public void setId(java.lang.String id)
Description copied from interface: Component
Sets the ID. The scope of uniqueness depends on whether this component is a root component. Refer to Component.getId() for more details.

Default: "" (an empty string; it means no ID at all).

Specified by:
setId in interface Component
Overrides:
setId in class AbstractComponent
Parameters:
id - the identifier. You could specify null or an empty string to remove ID.

Selectors

setVisible

public boolean setVisible(boolean visible)
Description copied from interface: Component
Sets whether this component is visible.

Specified by:
setVisible in interface Component
Overrides:
setVisible in class AbstractComponent
Returns:
the previous visibility

redraw

public void redraw(java.io.Writer out)
            throws java.io.IOException
Description copied from class: AbstractComponent
Redraws this component and all its descendants.

Default: It uses JsContentRenderer to render all information in JavaScript codes. For devices that don't support JavaScript, it must override this method.

To generate all information, it first invokes AbstractComponent.renderProperties(org.zkoss.zk.ui.sys.ContentRenderer) to render component's properties, and then AbstractComponent.redrawChildren(java.io.Writer) to redraw children (and descendants) (by calling their AbstractComponent.redraw(java.io.Writer)).

If a derived class wants to render more properties, it can override AbstractComponent.renderProperties(org.zkoss.zk.ui.sys.ContentRenderer).

If a derived class renders only a subset of its children (such as paging/cropping), it could override AbstractComponent.redrawChildren(java.io.Writer).

If a deriving class wants to do something before AbstractComponent.renderProperties(org.zkoss.zk.ui.sys.ContentRenderer), it has to override AbstractComponent.redraw(java.io.Writer).

If a deriving class doesn't want to render in JavaScript codes, it has to override AbstractComponent.redraw(java.io.Writer) with the proper implementation of ContentRenderer.

Specified by:
redraw in interface ComponentCtrl
Overrides:
redraw in class AbstractComponent
Throws:
java.io.IOException

setTag

public void setTag(java.lang.String tag)
            throws WrongValueException
Sets the tag name.

Specified by:
setTag in interface DynamicTag
Parameters:
tag - the tag name. If null or empty, plain text is assumed.
Throws:
WrongValueException

hasTag

public boolean hasTag(java.lang.String tag)
Description copied from interface: DynamicTag
Returns whether the specified tag is allowed.

Specified by:
hasTag in interface DynamicTag

hasDynamicProperty

public boolean hasDynamicProperty(java.lang.String name)
Description copied from interface: DynamicPropertied
Returns whether a dynamic property is defined.

Specified by:
hasDynamicProperty in interface DynamicPropertied

getDynamicProperty

public java.lang.Object getDynamicProperty(java.lang.String name)
Description copied from interface: DynamicPropertied
Returns the property value of the specified name.

Specified by:
getDynamicProperty in interface DynamicPropertied

setDynamicProperty

public void setDynamicProperty(java.lang.String name,
                               java.lang.Object value)
                        throws WrongValueException
Description copied from interface: DynamicPropertied
Sets a property with the specified name and value.

If a component supports only String-type values, it could use org.zkoss.lang.Objects.toString() to convert the value to a String instance.

Specified by:
setDynamicProperty in interface DynamicPropertied
Throws:
WrongValueException
