java.lang.Objectjavax.faces.el.PropertyResolver
ELResolver.
public abstract class PropertyResolver
PropertyResolver represents a pluggable mechanism
 for accessing a "property" of an underlying Java object instance.
 Different PropertyResolver implementations can support
 property resolution on instances of different Java classes (such as
 introspection-based access to properties of a JavaBeans component, or
 get() and put() calls on a
 java.util.Map instance).
All implementations must respect the rules for JavaBeans component,
 java.util.Map, java.util.List and array
 instances defined for each method but are allowed to add custom
 semantics for other types.

                                          PropertyNotFoundException
Return the value of the specified property from the specified base object.
For a bean base object, the property is coerced to a
 String and used as the property name.
 For all other base object types (e.g., a Map), the property is used
 without any coercing.
base - The base object whose property value is to be returnedproperty - The property to be returned
null if base
  or property is null, or if the property
  doesn't exist and the base object is a Map instance
EvaluationException - if an exception is thrown while getting
  the property value (the thrown exception must be included as the
  cause property of this exception)
PropertyNotFoundException - if the specified property
  for a bean base object does not exist or is not readable
public abstract java.lang.Object getValue(java.lang.Object base,
                                          int index)

                                          PropertyNotFoundException
Return the value at the specified index of the specified base object.
base - The base object whose property value is to be returnedindex - The index of the value to return
null if base
  is null, or if the index is out of bounds for the base
  object
EvaluationException - if an exception is thrown while getting
  the property value (the thrown exception must be included as the
  cause property of this exception)
PropertyNotFoundException - if the index is out of
  bounds or if base is null

                       throws EvaluationException,
                              PropertyNotFoundException
Set the specified value of the specified property on the specified base object.
For a bean base object, the property is coerced to a
 String and used as the property name.
 For all other base object types (e.g., a Map), the property is used
 without any coercing.
base - The base object whose property value is to be setproperty - The property to be setvalue - The value of the property to be set
EvaluationException - if an exception is thrown while setting
  the property value (the thrown exception must be included as the
  cause property of this exception)
PropertyNotFoundException - if the specified bean base
  object property does not exist or is not writeable, or if
  base or name is null

                       throws EvaluationException,
                              PropertyNotFoundException
Set the value at the specified index of the specified base object.
base - The base object whose property value is to be setindex - The index of the value to setvalue - The value to be set
EvaluationException - if an exception is thrown while setting
  the property value (the thrown exception must be included as the

  bounds or if base is null

                                   PropertyNotFoundException
Checks if the specified property is read-only.
For a bean base object, the property is coerced to a
 String and used as the property name.
 For all other base object types (e.g., a Map), the property is used
 without any coercing.
base - The base object whose property is to be analyzedproperty - The property to be analyzed
true if the specified property of the specified
  base object is known to be immutable; otherwise false
EvaluationException - if an exception is thrown while testing
  the property (the thrown exception must be included as the
  cause property of this exception)
PropertyNotFoundException - if the specified bean base
  object property does not exist or if base or 
  property is null
public abstract boolean isReadOnly(java.lang.Object base,

                                   PropertyNotFoundException
Checks if the specified index is read-only.

true if the value at the specified index of
  the specified base object is known to be immutable; otherwise,
  false

                                        PropertyNotFoundException
Return the java.lang.Class representing the type
 of the specified property.  An instance of any Object of that
 type my be set as the value of that property, as long as the
 property is not read-only.  The actual value of the property, if
 non-null, is guaranteed to be an instance of this type, or an
 instance of a subclass of this type.  This method is also useful
 for discovering the type of Objects that may be set as the value
 of the property.
For a bean base object, the property is coerced to a
 String and used as the property name.  For all other
 base object types (e.g., a Map), the property is used without any
 coercing.

java.lang.Class representing the type of
  the specified property of the specified base object, if it can be
  determined; otherwise null
EvaluationException - if an exception is thrown while testing
  the property (the thrown exception must be included as the
  cause property of this exception)
PropertyNotFoundException - if the specified bean base
  object property does not exist or if base or
  property is null

Return the java.lang.Class representing the type of
 the specified index.
