      • getVariableName

        public static String getVariableName(Object value)
        Determine the conventional variable name for the supplied Object based on its concrete type. The convention used is to return the uncapitalized short name of the Class, according to JavaBeans property naming rules: So, com.myapp.Product becomes product; com.myapp.MyProduct becomes myProduct; com.myapp.UKProduct becomes UKProduct.

        For arrays, we use the pluralized version of the array component type. For Collections we attempt to 'peek ahead' in the Collection to determine the component type and return the pluralized version of that component type.

        Parameters:
        value - the value to generate a variable name for
        Returns:
        the generated variable name
      • getVariableNameForParameter

        public static String getVariableNameForParameter(MethodParameter parameter)
        Determine the conventional variable name for the supplied parameter, taking the generic collection type (if any) into account.
        Parameters:
        parameter - the method or constructor parameter to generate a variable name for
        Returns:
        the generated variable name
      • getVariableNameForReturnType

        public static String getVariableNameForReturnType(Method method)
        Determine the conventional variable name for the return type of the supplied method, taking the generic collection type (if any) into account.
        Parameters:
        method - the method to generate a variable name for
        Returns:
        the generated variable name
      • getVariableNameForReturnType

        public static String getVariableNameForReturnType(Method method,
                                          Object value)
        Determine the conventional variable name for the return type of the supplied method, taking the generic collection type (if any) into account, falling back to the given return value if the method declaration is not specific enough (i.e. in case of the return type being declared as Object or as untyped collection).
        Parameters:
        method - the method to generate a variable name for
        value - the return value (may be null if not available)
        Returns:
        the generated variable name
      • getVariableNameForReturnType

        public static String getVariableNameForReturnType(Method method,
                                          Class resolvedType,
                                          Object value)
        Determine the conventional variable name for the return type of the supplied method, taking the generic collection type (if any) into account, falling back to the given return value if the method declaration is not specific enough (i.e. in case of the return type being declared as Object or as untyped collection).
        Parameters:
        method - the method to generate a variable name for
        resolvedType - the resolved return type of the method
        value - the return value (may be null if not available)
        Returns:
        the generated variable name
      • attributeNameToPropertyName

        public static String attributeNameToPropertyName(String attributeName)
        Convert Strings in attribute name format (lowercase, hyphens separating words) into property name format (camel-cased). For example, transaction-manager is converted into transactionManager.
      • getQualifiedAttributeName

        public static String getQualifiedAttributeName(Class enclosingClass,
                                       String attributeName)
        Return an attribute name qualified by the supplied enclosing Class. For example, the attribute name ' foo' qualified by Class ' com.myapp.SomeClass' would be ' com.myapp.SomeClass.foo'
