Method Detail

coerceToType

public Object coerceToType(Object obj,
                           Class<?> type)

Coerces an object to a specific type according to the Jakarta Expression Language type conversion rules. The custom type conversions in the ELResolvers are not considered. Jakarta Expression Language version 2.2 backward compatibility conversion rules apply if ExpressionFactoryImpl was created with property "jakarta.el.bc2.2" set to true.
