  Create a MethodExpression, using this attribute's value as the expression String.

  Parameters:

  ctx - FaceletContext to use

  type - expected return type

  paramTypes - parameter type

  Returns:

  a MethodExpression instance

• getNamespace

  public abstract String getNamespace()

  The resolved Namespace for this attribute

  Returns:

  resolved Namespace

• getObject

  public abstract Object getObject(FaceletContext ctx)

  Delegates to getObject with Object.class as a param

  Parameters:

  ctx - FaceletContext to use

  Returns:

  Object representation of this attribute's value

  See Also:

  getObject(FaceletContext, Class)

• getQName

  public abstract String getQName()

  The qualified name for this attribute

  Returns:

  the qualified name for this attribute

• getValue

  public abstract String getValue()

  Return the literal value of this attribute

  Returns:

  literal value

• getValue

  public abstract String getValue(FaceletContext ctx)

  If literal, then return our value, otherwise delegate to getObject, passing String.class.

  Parameters:

  ctx - FaceletContext to use

  Returns:

  String value of this attribute

  See Also:

  getObject(FaceletContext, Class)

• getObject

  public abstract Object getObject(FaceletContext ctx,
                                   Class type)

  If literal, simply coerce our String literal value using an ExpressionFactory, otherwise create a ValueExpression and evaluate it.

  Parameters:

  ctx - FaceletContext to use

  type - expected return type

  Returns:

  Object value of this attribute

  See Also:

  ExpressionFactory.coerceToType(java.lang.Object, java.lang.Class), ExpressionFactory.createValueExpression(javax.el.ELContext, java.lang.String, java.lang.Class), ValueExpression

• getValueExpression

  public abstract ValueExpression getValueExpression(FaceletContext ctx,
                                                     Class type)

  Create a ValueExpression, using this attribute's literal value and the passed expected type.

  Parameters:

  ctx - FaceletContext to use

  type - expected return type

  Returns:

  ValueExpression instance

  See Also:

  ExpressionFactory.createValueExpression(javax.el.ELContext, java.lang.String, java.lang.Class), ValueExpression

• isLiteral

  public abstract boolean isLiteral()

  If this TagAttribute is literal (not #{..} or ${..})

  Returns:

  true if this attribute is literal

• getTag

  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.

  Returns:

  the Tag for which this class represents the attributes.

  Since:

  2.2

• setTag

  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 FaceletHandlers for this element are instantiated. For compatibility with previous implementations, a no-op implementation is provided.

  Since:

  2.2
