Method Detail

getType

public Class getType(Object base,
                     int index)
              throws jakarta.faces.el.EvaluationException,
                     jakarta.faces.el.PropertyNotFoundException

Description copied from class: jakarta.faces.el.PropertyResolver

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

Specified by:

getType in class jakarta.faces.el.PropertyResolver

Parameters:

base - The base object whose property is to be analyzed

index - The index of the value whose type is to be returned

Returns:

The java.lang.Class representing the type of value at the specified index of the specified base object, if it can be determined; otherwise null

Throws:

jakarta.faces.el.EvaluationException - if an exception is thrown while testing the property (the thrown exception must be included as the cause property of this exception)

jakarta.faces.el.PropertyNotFoundException - if the index is out of bounds or if base is null

getType

public Class getType(Object base,
                     Object property)

Description copied from class: jakarta.faces.el.PropertyResolver

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.

Specified by:

getType in class jakarta.faces.el.PropertyResolver

Parameters:

base - The base object whose property is to be analyzed

property - The property to be analyzed

Returns:

the java.lang.Class representing the type of the specified property of the specified base object, if it can be determined; otherwise null

getValue

public Object getValue(Object base,
                       int index)

Description copied from class: jakarta.faces.el.PropertyResolver

Return the value at the specified index of the specified base object.

Specified by:

getValue in class jakarta.faces.el.PropertyResolver

Parameters:

base - The base object whose property value is to be returned

index - The index of the value to return

Returns:

The property value, or null if base is null, or if the index is out of bounds for the base object

getValue

public Object getValue(Object base,
                       Object property)

Description copied from class: jakarta.faces.el.PropertyResolver

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.

Specified by:

getValue in class jakarta.faces.el.PropertyResolver

Parameters:

base - The base object whose property value is to be returned

property - The property to be returned

Returns:

The property value, or null if base or property is null, or if the property doesn't exist and the base object is a Map instance

isReadOnly

public boolean isReadOnly(Object base,
                          int index)

Description copied from class: jakarta.faces.el.PropertyResolver

Checks if the specified index is read-only.

Specified by:

isReadOnly in class jakarta.faces.el.PropertyResolver

Parameters:

base - The base object whose property is to be analyzed

index - The index of the value whose type is to be returned

Returns:

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

isReadOnly

public boolean isReadOnly(Object base,
                          Object property)

Description copied from class: jakarta.faces.el.PropertyResolver

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.

Specified by:

isReadOnly in class jakarta.faces.el.PropertyResolver

Parameters:

base - The base object whose property is to be analyzed

property - The property to be analyzed

Returns:

true if the specified property of the specified base object is known to be immutable; otherwise false

setValue

public void setValue(Object base,
                     int index,
                     Object value)

Description copied from class: jakarta.faces.el.PropertyResolver

Set the value at the specified index of the specified base object.

Specified by:

setValue in class jakarta.faces.el.PropertyResolver

Parameters:

base - The base object whose property value is to be set

index - The index of the value to set

value - The value to be set

setValue

public void setValue(Object base,
                     Object property,
                     Object value)

Description copied from class: jakarta.faces.el.PropertyResolver

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.

Specified by:

setValue in class jakarta.faces.el.PropertyResolver

Parameters:

base - The base object whose property value is to be set

property - The property to be set

value - The value of the property to be set

setDelegate

public void setDelegate(jakarta.faces.el.PropertyResolver delegate)

                                  Object property)
                           throws jakarta.faces.el.PropertyNotFoundException

Throws:

jakarta.faces.el.PropertyNotFoundException

assertInput

protected static void assertInput(Object base,
                                  int index)
                           throws jakarta.faces.el.PropertyNotFoundException
