Context representative of a single request from a Facelet. This instance is passed to nearly every method call in this API.

Since:
2.0
 
 public abstract class FaceletContext extends ELContext {
     
     // The key in the FacesContext attribute map
     // for the FaceletContext instance.
     public static final String FACELET_CONTEXT_KEY = 
             "com.sun.faces.facelets.FACELET_CONTEXT";

    

The current FacesContext bound to this "request". Must not be null.

Since:
2.0
 
     public abstract FacesContext getFacesContext();

    

Generate a unique ID for the passed String

Parameters:
base the string from which to generate the ID.
Since:
2.0
    public abstract String generateUniqueId(String base);

    

The ExpressionFactory to use within the Facelet this context is executing upon. Must not be null.

Since:
2.0
    public abstract ExpressionFactory getExpressionFactory();

    

Set the VariableMapper to use in EL evaluation/creation.

Parameters:
varMapper the new VariableMapper
Since:
2.0
    public abstract void setVariableMapper(VariableMapper varMapper);

    

Set the FunctionMapper to use in EL evaluation/creation.

Parameters:
fnMapper the new FunctionMapper
Since:
2.0
    public abstract void setFunctionMapper(FunctionMapper fnMapper);

    

Support method which is backed by the current VariableMapper.

Parameters:
name the name of the attribute
value the value of the attribute
Since:
2.0
    public abstract void setAttribute(String nameObject value);

    

Return an attribute set by a previous call to setAttribute(java.lang.String,java.lang.Object). Support method which is backed by the current VariableMapper

Parameters:
name the name of the attribute to return.
Since:
2.0
    public abstract Object getAttribute(String name);

    

Include another Facelet defined at some path, relative to the executing context, not the current Facelet (same as include directive in JSP)

Parameters:
parent the UIComponent that will be the parent of any components in the included facelet.
relativePath the path of the resource containing the facelet markup, relative to the current markup
Throws:
java.io.IOException if unable to load relativePath
FaceletException if unable to parse the markup loaded from relativePath
FacesException if unable to create child UIComponent instances
ELException if any of the expressions in the markup loaded from relativePath fail
Since:
2.0
    public abstract void includeFacelet(UIComponent parentString relativePath)
    throws IOException;

    

Include another Facelet defined at some path, absolute to this ClassLoader/OS

Parameters:
parent the UIComponent that will be the parent of any components in the included facelet.
absolutePath the absolute path to the resource containing the facelet markup
Throws:
java.io.IOException if unable to load relativePath
FaceletException if unable to parse the markup loaded from relativePath
FacesException if unable to create child UIComponent instances
ELException if any of the expressions in the markup loaded from relativePath fail
    public abstract void includeFacelet(UIComponent parentURL absolutePath)
    throws IOException;
