Default FaceletContext implementation. A single FaceletContext is used for all Facelets involved in an invocation of Facelet#apply(FacesContext, UIComponent). This means that included Facelets are treated the same as the JSP include directive.

public boolean apply(FaceletContext ctx, UIComponent parent, String name) throws IOException

Implements com.sun.faces.facelets.TemplateClient.apply.

Doc from com.sun.faces.facelets.TemplateClient.apply.

This contract is much like the normal FaceletHandler.apply method, but it takes in an optional String name which tells this instance what fragment/definition it's looking for. If you are a match, apply your logic to the passed UIComponent and return true, otherwise do nothing and return false.

Parameters
ctx:FaceletContext

the FaceletContext of your instance, not the templates'

parent:UIComponent

current UIComponent instance to be applied

name:String

the String name or null if the whole body should be included

Returns:boolean

true if this client matched/applied the definition for the passed name

Annotations
@Override
equalsback to summary
public boolean equals(Object o)

Overrides java.lang.Object.equals.

Doc from java.lang.Object.equals.

Indicates whether some other object is "equal to" this one.

The equals method implements an equivalence relation on non-null object references:

  • It is reflexive: for any non-null reference value x, x.equals(x) should return true.
  • It is symmetric: for any non-null reference values x and y, x.equals(y) should return true if and only if y.equals(x) returns true.
  • It is transitive: for any non-null reference values x, y, and z, if x.equals(y) returns true and y.equals(z) returns true, then x.equals(z) should return true.
  • It is consistent: for any non-null reference values x and y, multiple invocations of x.equals(y) consistently return true or consistently return false, provided no information used in equals comparisons on the objects is modified.
  • For any non-null reference value x, x.equals(null) should return false.

An equivalence relation partitions the elements it operates on into equivalence classes; all the members of an equivalence class are equal to each other. Members of an equivalence class are substitutable for each other, at least for some purposes.

Parameters
o:Object

the reference object with which to compare.

Returns:boolean

true if this object is the same as the obj argument; false otherwise.
