Method Detail

getClassFromType

public static java.lang.Class<?> getClassFromType(PropertyCollection<?,?> typeToMatch)

Find the java class associated with a property type. For instance, for the deduced.boolean type is associated with the java.lang.Boolean class.

Parameters:

typeToMatch - the type to match. This class should extend the deduced.PropertyType type.

Returns:

the associated java class. If the type can't be matched, the value returned will be null. If the type is a property collection type, then a generic deduced.PropertyCollection class will be returned.

associatedTypeAndClass

private static void associatedTypeAndClass(PropertyCollection<?,?> type,
                                           java.lang.Class<?> javaClass)

associatedTypeAndClass

Parameters:

type - the deduced type

javaClass - the associated java class

initialize

public static void initialize()

initialize the class to map association

getNativeClassFromType

public static java.lang.Class<?> getNativeClassFromType(PropertyCollection<?,?> typeToMatch)

fetch the java native class for a specified type. For instance, the INTEGER_TYPE will return java.lang.Integer.TYPE instead of returning java.lang.Integer.class

Parameters:

typeToMatch - the type to match

Returns:

the java native type.

isTypeNative

public static boolean isTypeNative(PropertyCollection<?,?> typeToMatch)

test to see if a type is native or not. Native types are types such as int, char, double, boolean, string.

Parameters:

typeToMatch - the type to test if it is native

Returns:

true if the type is native.

getTypeFromClass

public static PropertyCollection<?,?> getTypeFromClass(java.lang.Class<?> classToMatch)

find a property type from a Java Class. For instance, the java.lang.Boolean will return the deduced.boolean type. If the class being passed is a property collection, then a generic deduced.PropertyCollection is returned.

Parameters:

classToMatch - the java class to match

Returns:

the deduced property type being used. Returns null if the class being passed as a parameter can't be matched.

isTypeNumeric

public static boolean isTypeNumeric(PropertyCollection<?,?> type)

test if a type is numeric

Parameters:

type - the type to test

Returns:

false if the type is null or not numeric.
