Doc from jakarta.el.CompositeELResolver.getType.

For a given base and property, attempts to identify the most general type that is acceptable for an object to be passed as the value parameter in a future call to the setValue method. The result is obtained by querying all component resolvers.

If this resolver handles the given (base, property) pair, the propertyResolved property of the ELContext object must be set to true by the resolver, before returning. If this property is not true after this method is called, the caller should ignore the return value.

First, propertyResolved is set to false on the provided ELContext.

Next, for each component resolver in this composite:

The getType() method is called, passing in the provided context, base and property.
If the ELContext's propertyResolved flag is false then iteration continues.
Otherwise, iteration stops and no more component resolvers are considered. The value returned by getType() is returned by this method.

If none of the component resolvers were able to perform this operation, the value null is returned and the propertyResolved flag remains set to false.

Any exception thrown by component resolvers during the iteration is propagated to the caller of this method.

Parameters

context:ELContext: The context of this evaluation.
base:Object: The base object whose property value is to be analyzed, or null to analyze a top-level variable.
property:Object: The property or variable to return the acceptable type for.
