ELResolver.public abstract class PropertyResolver extends Object
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.

public abstract Object getValue(Object base, Object property) throws EvaluationException, 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 returnednull if base
  or property is null, or if the property
  doesn't exist and the base object is a Map instanceEvaluationException - 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 readablepublic abstract Object getValue(Object base, int index) throws EvaluationException, 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 returnnull if base
  is null, or if the index is out of bounds for the base
  objectEvaluationException - 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 nullpublic abstract void setValue(Object base, Object property, Object value) 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 setEvaluationException - 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 nullpublic abstract void setValue(Object base, int index, Object value) 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 setEvaluationException - if an exception is thrown while setting
  the property value (the thrown exception must be included as the

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 object is known to be immutable; otherwise falseEvaluationException - if an exception is thrown while testing

  cause property of this exception)PropertyNotFoundException - if the specified bean base
  object property does not exist or if base or

Checks if the specified index is read-only.

  falseEvaluationException - 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 index is out of
  bounds or if base is nullpublic abstract Class getType(Object base, Object property) throws EvaluationException, 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.
