renderBooleanPassthruAttributes

public static void renderBooleanPassthruAttributes(javax.faces.context.FacesContext context,
                                                   javax.faces.component.UIComponent component)
                                            throws java.io.IOException

Throws:

java.io.IOException

renderPassthruAttributes

public static void renderPassthruAttributes(javax.faces.context.FacesContext context,
                                            javax.faces.component.UIComponent component)
                                     throws java.io.IOException

Throws:

java.io.IOException

renderEventHandlerPassthruAttributes

public static void renderEventHandlerPassthruAttributes(javax.faces.context.FacesContext context,
                                                        javax.faces.component.UIComponent component)
                                                 throws java.io.IOException

Throws:

java.io.IOException

getStringAttribute

public static java.lang.String getStringAttribute(javax.faces.component.UIComponent component,
                                                  java.lang.String attribute)

This operation is a convenience helper that checks the type safety for the attributes of type String.This operation throws an appropriate exception, or returns the down-casted string for a given attribute.

Parameters:

component - the component to query for the attribute.

attribute - the attribute to query for.

Returns:

The string value for the attribute, or null if attribute not present.

Throws:

java.lang.IllegalArgumentException - when the requested attribute turns out to be of a different type than java.lang.String.

getBooleanAttribute

public static java.lang.Boolean getBooleanAttribute(javax.faces.component.UIComponent component,
                                                    java.lang.String attribute)

This operation is a convenience helper that checks the type safety for the attributes of type Boolean.This operation throws an appropriate exception, or returns a primitive boolean for a given attribute.

Parameters:

component - the component to query for the attribute.

attribute - the attribute to query for.

Returns:

The string value for the attribute.

Throws:

java.lang.IllegalArgumentException - when the requested attribute turns out to be of a different type than java.lang.Boolean.

getNumericAttribute

public static java.lang.Long getNumericAttribute(javax.faces.component.UIComponent component,
                                                 java.lang.String attribute)

This operation retrieves a numeric attribute. It checks and converts the attribute into a Long, which provides for convenient access to the attribute. It also throws an IllegalArgumentException when the attribute is not of the requested type.

Parameters:

component - the component to check.

attribute - the attribute to look up.

Returns:

a long with the value or null if the attribute is not specified for the component.

getStringListAttribute

public static java.lang.String[] getStringListAttribute(javax.faces.component.UIComponent component,
                                                        java.lang.String attribute)

Retrieves a string list attribute from a specified component. This operation is useful to find and retrieve an attribute which is described in to have a comma separated list of elements. The individual elements are returned (in order) as a array of strings of easy interpretation. If the attribute is not available a null value is returned.

Parameters:

component - the component on which to look.

attribute - the attribute to look for.

Returns:

a String[] with the individual values or null if the attribute is not set on the component.

getEnclosingForm

public static javax.faces.component.UIForm getEnclosingForm(javax.faces.component.UIComponent component)

Looks for the closest UIForm ancestor component.

Parameters:

component -

Returns:

a UIForm or null if there is no enclosing UIForm available
