the value of the provided property

isReadOnly

public boolean isReadOnly(ELContext context,
 Object base,
 Object property)

Description copied from class: ELResolver

Determine if the given property on the given object is read-only using the given context.

Specified by:

isReadOnly in class ELResolver

Parameters:

context - The EL context for this evaluation

base - The base object on which the property is to be found

property - The property to be checked for read only status

getCommonPropertyType

public Class<?> getCommonPropertyType(ELContext context,
 Object arg)

Description copied from class: ELResolver

Obtain the most common type that is acceptable for the given base object.

Specified by:

getCommonPropertyType in class ELResolver

Parameters:

context - The context in which the examination takes place

arg - The object to examine

Returns:

{code null} if the most common type cannot be determined, otherwise the most common type

getType

public Class<?> getType(ELContext context,
 Object arg1,
 Object arg2)

Description copied from class: ELResolver

Obtain the most generally acceptable type that may be used to set the given property on the given object using the given context.

Specified by:

getType in class ELResolver

Parameters:

context - The EL context for this evaluation

arg1 - The base object on which the property is to be found

arg2 - The property whose type is to be returned
