java.lang.Object

org.zkoss.zk.ui.AbstractComponent

org.zkoss.zml.XmlNativeComponent

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.

Since:

3.0.0

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
