  • Method Details

    • coerceToType

      public <T> T coerceToType(Object obj, Class<T> type)
      Description copied from class: jakarta.el.ExpressionFactory
      Coerce the supplied object to the requested type.
      Specified by:
      coerceToType in class ExpressionFactory
      Type Parameters:
      T - The type to which the object should be coerced
      Parameters:
      obj - The object to be coerced
      type - The type to which the object should be coerced
      Returns:
      An instance of the requested type.

    • createMethodExpression

      public MethodExpression createMethodExpression(ELContext context, String expression, Class<?> expectedReturnType, Class<?>[] expectedParamTypes)
      Description copied from class: jakarta.el.ExpressionFactory
      Create a new method expression instance.
      Specified by:
      createMethodExpression in class ExpressionFactory
      Parameters:
      context - The EL context for this evaluation
      expression - The String representation of the method expression
      expectedReturnType - The expected type of the result of invoking the method
      expectedParamTypes - The expected types of the input parameters
      Returns:
      A new method expression formed from the input parameters.

    • createValueExpression

      public ValueExpression createValueExpression(ELContext context, String expression, Class<?> expectedType)
      Description copied from class: jakarta.el.ExpressionFactory
      Create a new value expression.
      Specified by:
      createValueExpression in class ExpressionFactory
      Parameters:
      context - The EL context for this evaluation
      expression - The String representation of the value expression
      expectedType - The expected type of the result of evaluating the expression
      Returns:
      A new value expression formed from the input parameters

    • createValueExpression

      public ValueExpression createValueExpression(Object instance, Class<?> expectedType)
      Description copied from class: jakarta.el.ExpressionFactory
      Creates a ValueExpression that, when evaluated, returns the given instance of the specified type. This is a convenience method for creating a constant value expression without requiring an ELContext.
      Specified by:
      createValueExpression in class ExpressionFactory
      Parameters:
      instance - the constant value to wrap
      expectedType - the expected type of the value
      Returns:
      a ValueExpression that returns the given instance when evaluated

    • getStreamELResolver

      public ELResolver getStreamELResolver()
      Description copied from class: jakarta.el.ExpressionFactory
      Returns an ELResolver capable of resolving properties on InputStream objects, enabling EL expressions to operate on stream types. This allows expressions to read data from input streams using standard property navigation syntax.
      Overrides:
      getStreamELResolver in class ExpressionFactory
      Returns:
      the StreamELResolver, or null if not supported by this implementation
