Method Detail

getTypeCode

public static int getTypeCode(Class<?> type)

Return the field metadata type code for the given class. First class objects are not recognized in this method.

classForName

public static Class<?> classForName(String name,
                                    ClassMetaData context)

Check the given name against the same set of standard packages used when parsing metadata.

classForName

public static Class<?> classForName(String name,
                                    ClassMetaData context,
                                    ClassLoader loader)

Check the given name against the same set of standard packages used when parsing metadata.

classForName

public static Class<?> classForName(String name,
                                    ValueMetaData context)

Check the given name against the same set of standard packages used when parsing metadata.

classForName

public static Class<?> classForName(String name,
                                    ValueMetaData context,
                                    ClassLoader loader)

Check the given name against the same set of standard packages used when parsing metadata.

convert

public static Object convert(Object val,
                             int typeCode)

Convert the given object to the given type if possible. If the type is a numeric primitive, this method only guarantees that the return value is a Number. If no known conversion or the value is null, returns the original value.

maybePC

public static boolean maybePC(FieldMetaData field)

Return true if the (possibly unresolved) field or its elements might be persistence capable objects.

maybePC

public static boolean maybePC(ValueMetaData val)

Return true if the (possibly unresolved) value might be a first class object.

maybePC

static boolean maybePC(int typeCode,
                       Class<?> type)

Return true if the given unresolved typecode/type pair may represent a persistent object.

toList

public static List toList(Object val,
                          Class<?> elem,
                          boolean mutable)

Helper method to return the given array value as a collection.

toArray

public static Object toArray(Collection<?> coll,
                             Class<?> elem)

Helper method to return the given collection as an array.
