Method Detail

getCommonPropertyType

public Class getCommonPropertyType(javax.el.ELContext context,
                                   Object base)

Return the most general type this resolver accepts for the property argument.

Specified by:
getCommonPropertyType in class javax.el.ELResolver

getFeatureDescriptors

public Iterator getFeatureDescriptors(javax.el.ELContext context,
                                      Object base)

Return an Iterator over the attributes that this resolver knows how to deal with.

Specified by:
getFeatureDescriptors in class javax.el.ELResolver
Parameters:
context - ELContext for evaluating this value
base - Base object against which this evaluation occurs

getType

public Class getType(javax.el.ELContext context,
                     Object base,
                     Object property)

Return the Java type of the specified property.

Specified by:
getType in class javax.el.ELResolver
Parameters:
context - ELContext for evaluating this value
base - Base object against which this evaluation occurs (must be null because we are evaluating a top level variable)
property - Property name to be accessed

getValue

public Object getValue(javax.el.ELContext context,
                       Object base,
                       Object property)

Evaluate with the legacy variable resolver chain and return the value.

Specified by:
getValue in class javax.el.ELResolver
Parameters:
context - ELContext for evaluating this value
base - Base object against which this evaluation occurs (must be null because we are evaluating a top level variable)
property - Property name to be accessed

isReadOnly

public boolean isReadOnly(javax.el.ELContext context,
                          Object base,
                          Object property)

Return true if the specified property is read only.

Specified by:
isReadOnly in class javax.el.ELResolver
Parameters:
context - ELContext for evaluating this value
base - Base object against which this evaluation occurs (must be null because we are evaluating a top level variable)
property - Property name to be accessed

setValue

public void setValue(javax.el.ELContext context,
                     Object base,
                     Object property,
                     Object value)

Set the value of a scoped object for the specified name.

Specified by:
setValue in class javax.el.ELResolver
Parameters:
context - ELContext for evaluating this value
base - Base object against which this evaluation occurs (must be null because we are evaluating a top level variable)
property - Property name to be accessed
value - New value to be set

descriptor

protected FeatureDescriptor descriptor(String name,
                                       String displayName,
                                       String description,
