Method Detail

getAssignableValue

public static java.lang.Object getAssignableValue(java.lang.Class clzRequiredType,
                                                  com.tangosol.config.expression.Parameter parameter,
                                                  com.tangosol.config.expression.ParameterResolver resolver,
                                                  java.lang.ClassLoader loader)
                                           throws java.lang.ClassNotFoundException,
                                                  java.lang.ClassCastException

Obtains an assignment compatible value of the required type given an actual Parameter.

This allows us to accept parameters and produce an Object value that may be assigned using Java reflection.

Parameters:

clzRequiredType - the required type of value

parameter - the actual Parameter from which to determine the value

resolver - the ParameterResolver to resolve Parameters used in Parameters

loader - the ClassLoader to use for loading necessary classes (required)

Returns:

an object that is assignable to the required type

Throws:

ClassNotFoundException, - ClassCastException when it's not possible to determine an assignable value

java.lang.ClassNotFoundException

java.lang.ClassCastException

isAssignablePrimitive

public static boolean isAssignablePrimitive(java.lang.Class clzPrimitive,
                                            java.lang.Class clzWrapper)

Determines if a primitive type is assignable to a wrapper type.

Parameters:

clzPrimitive - the primitive class type

clzWrapper - the wrapper class type

Returns:

true if primitive and wrapper are assignment compatible

realizes

public static boolean realizes(ParameterizedBuilder bldr,
                               java.lang.Class clzClass,
                               com.tangosol.config.expression.ParameterResolver resolver,
                               java.lang.ClassLoader loader)

Determines if a ParameterizedBuilder will build a specified Class of object.

Parameters:

bldr - the ParameterizedBuilder

clzClass - the Class of object expected

resolver - a ParameterResolver to resolve parameters

loader - the ClassLoader to use if classes need to be loaded

Returns:

true if the ParameterizedBuilder will build the specified Class of object, false otherwise
