Deprecated.

This has been replaced by ELResolver.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.

Method Detail

getValue

public abstract Object getValue(Object base,
                                Object property)
                         throws EvaluationException,
                                PropertyNotFoundException

Deprecated.

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.

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

Throws:

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

getValue

public abstract Object getValue(Object base,
                                int index)
                         throws EvaluationException,
                                PropertyNotFoundException

Deprecated.

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

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

Throws:

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

setValue

public abstract void setValue(Object base,
                              Object property,
                              Object value)
                       throws EvaluationException,
                              PropertyNotFoundException

Deprecated.

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.

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

Throws:

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

setValue

public abstract void setValue(Object base,
                              int index,
                              Object value)
                       throws EvaluationException,
                              PropertyNotFoundException

Deprecated.

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

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

Throws:

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 index is out of bounds or if base is null

isReadOnly

public abstract boolean isReadOnly(Object base,
                                   Object property)
                            throws EvaluationException,
                                   PropertyNotFoundException

Deprecated.

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.

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

Throws:

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

isReadOnly

public abstract boolean isReadOnly(Object base,
                                   int index)
                            throws EvaluationException,
                                   PropertyNotFoundException

Deprecated.

Checks if the specified index is read-only.

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

Throws:

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 index is out of bounds or if base is null

getType

public abstract Class getType(Object base,
                              Object property)
                       throws EvaluationException,
                              PropertyNotFoundException

Deprecated.

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.

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

Throws:

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

getType

public abstract Class getType(Object base,
                              int index)
                       throws EvaluationException,
                              PropertyNotFoundException

Deprecated.

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

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:

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 index is out of bounds or if base is null
