getType
public Class<?> getType(javax.el.ELContext context, Object base, Object property)
Description copied from class:BeanELResolver
If the base object is not null, returns the most general acceptable type that can be set on this bean property. If the base is not null, the propertyResolved property of the ELContext object must be set to true by this resolver, before returning. If this property is not true after this method is called, the caller should ignore the return value. The provided property will first be coerced to a String. If there is a BeanInfoProperty for this property and there were no errors retrieving it, the propertyType of the propertyDescriptor is returned. Otherwise, a PropertyNotFoundException is thrown.- Overrides:
getType
in classBeanELResolver
- Parameters:
context
- The context of this evaluation.base
- The bean to analyze.property
- The name of the property to analyze. Will be coerced to a String.- Returns:
- If the propertyResolved property of ELContext was set to true, then the most general acceptable type; otherwise undefined.
-
getValue
public Object getValue(javax.el.ELContext context, Object base, Object property)
Description copied from class:BeanELResolver
If the base object is not null, returns the current value of the given property on this bean. If the base is not null, the propertyResolved property of the ELContext object must be set to true by this resolver, before returning. If this property is not true after this method is called, the caller should ignore the return value. The provided property name will first be coerced to a String. If the property is a readable property of the base object, as per the JavaBeans specification, then return the result of the getter call. If the getter throws an exception, it is propagated to the caller. If the property is not found or is not readable, a PropertyNotFoundException is thrown.- Overrides:
getValue
in classBeanELResolver
- Parameters:
context
- The context of this evaluation.base
- The bean to analyze.property
- The name of the property to analyze. Will be coerced to a String.- Returns:
- If the propertyResolved property of ELContext was set to true, then the value of the given property. Otherwise, undefined.
-
isReadOnly
public boolean isReadOnly(javax.el.ELContext context, Object base, Object property)
Description copied from class:BeanELResolver
If the base object is not null, returns whether a call toBeanELResolver.setValue(ELContext, Object, Object, Object)
will always fail. If the base is not null, the propertyResolved property of the ELContext object must be set to true by this resolver, before returning. If this property is not true after this method is called, the caller can safely assume no value was set.- Overrides:
isReadOnly
in classBeanELResolver
- Parameters:
context
- The context of this evaluation.base
- The bean to analyze.property
- The name of the property to analyze. Will be coerced to a String.- Returns:
- If the propertyResolved property of ELContext was set to true, then true if calling the setValue method will always fail or false if it is possible that such a call may succeed; otherwise undefined.
-
setValue
public void setValue(javax.el.ELContext context, Object base, Object property, Object value)
Description copied from class:BeanELResolver
If the base object is not null, attempts to set the value of the given property on this bean. If the base is not null, the propertyResolved property of the ELContext object must be set to true by this resolver, before returning. If this property is not true after this method is called, the caller can safely assume no value was set. If this resolver was constructed in read-only mode, this method will always throw PropertyNotWritableException. The provided property name will first be coerced to a String. If property is a writable property of base (as per the JavaBeans Specification), the setter method is called (passing value). If the property exists but does not have a setter, then a PropertyNotFoundException is thrown. If the property does not exist, a PropertyNotFoundException is thrown.- Overrides:
setValue
in classBeanELResolver
- Parameters:
context
- The context of this evaluation.base
- The bean to analyze.property
- The name of the property to analyze. Will be coerced to a String.value
- The value to be associated with the specified key.
-
invoke
public Object invoke(javax.el.ELContext context, Object base, Object method, Class<?>[] paramTypes, Object[] params)
Description copied from class:BeanELResolver
If the base object is notnull
, invoke the method, with the given parameters on this bean. The return value from the method is returned.If the base is not
null
, thepropertyResolved
property of theELContext
object must be set totrue
by this resolver, before returning. If this property is nottrue
after this method is called, the caller should ignore the return value.The provided method object will first be coerced to a
String
. The methods in the bean is then examined and an attempt will be made to select one for invocation. If no suitable can be found, aMethodNotFoundException
is thrown. If the given paramTypes is notnull
, select the method with the given name and parameter types. Else select the method with the given name that has the same number of parameters. If there are more than one such method, the method selection process is undefined. Else select the method with the given name that takes a variable number of arguments. Note the resolution for overloaded methods will likely be clarified in a future version of the spec. The provided parameters are coerced to the corresponding parameter types of the method, and the method is then invoked.- Overrides:
invoke
in classBeanELResolver
- Parameters:
context
- The context of this evaluation.base
- The bean on which to invoke the methodmethod
- The simple name of the method to invoke. Will be coerced to aString
. If method is "<init>"or "<clinit>" a MethodNotFoundException is thrown.paramTypes
- An array of Class objects identifying the method's formal parameter types, in declared order. Use an empty array if the method has no parameters. Can benull
, in which case the method's formal parameter types are assumed to be unknown.params
- The parameters to pass to the method, ornull
if no parameters.- Returns:
- The result of the method invocation (
null
if the method has avoid
return type).
