Modifier and Type | Method and Description |
---|---|
abstract boolean |
getBoolean(FaceletContext ctx)
If literal,return
|
abstract int |
getInt(FaceletContext ctx)
If literal, call
Integer.parseInt(String) ,
otherwise call
getObject(FaceletContext, Class) . |
abstract java.lang.String |
getLocalName()
Local name of this attribute
|
abstract Location |
getLocation()
The location of this attribute in the FaceletContext
|
abstract MethodExpression |
getMethodExpression(FaceletContext ctx,
java.lang.Class type,
java.lang.Class[] paramTypes)
Create a MethodExpression, using this attribute's value as the expression
String.
|
abstract java.lang.String |
getNamespace()
The resolved Namespace for this attribute
|
abstract java.lang.Object |
getObject(FaceletContext ctx)
Delegates to getObject with Object.class as a param
|
abstract java.lang.Object |
getObject(FaceletContext ctx,
java.lang.Class type)
If literal, simply coerce our String literal value using an
ExpressionFactory, otherwise create a ValueExpression and evaluate it.
|
abstract java.lang.String |
getQName()
The qualified name for this attribute
|
Tag |
getTag()
A reference to the Tag for which this class represents the attributes. |
abstract java.lang.String |
getValue()
Return the literal value of this attribute
|
abstract java.lang.String |
getValue(FaceletContext ctx)
If literal, then return our value, otherwise delegate to getObject,
passing String.class.
|
abstract ValueExpression |
getValueExpression(FaceletContext ctx,
java.lang.Class type)
Create a ValueExpression, using this attribute's literal value and the
passed expected type.
|
abstract boolean |
isLiteral()
If this TagAttribute is literal (not #{..} or ${..})
|
void |
setTag(Tag tag)
Set a reference to the Tag for which this class represents the attributes. |
public abstract boolean getBoolean(FaceletContext ctx)

public Tag getTag()
A reference to the Tag for which this class
represents the attributes. For compatibility with previous
implementations, an implementation is provided that returns
null
.
Tag
for which this class represents the attributes.public void setTag(Tag tag)
Set a reference to the Tag for which this
class represents the attributes. The VDL runtime must ensure that this
method is called before any FaceletHandler
s for this element are instantiated. For compatibility
with previous implementations, a no-op implementation is provided.
tag
- the tag we represent.
