Constructor Summary
`ProxyManagerImpl()`

Method Summary
`protected boolean`	`allowsDuplicates(Class type)` Return whether the given collection type allows duplicates.
`Object`	`copyArray(Object orig)` Return a new array of the same component type as the given array and containing the same elements.
`Calendar`	`copyCalendar(Calendar orig)` Return a copy of the given calendar with the same information.
`Collection`	`copyCollection(Collection orig)` Return a new collection of the same type as the given one with a copy of all contained elements.
`Object`	`copyCustom(Object orig)` Return a copy of the given object with the same information, or null if this manager cannot copy the object.
`Date`	`copyDate(Date orig)` Return a copy of the given date with the same information.
`Map`	`copyMap(Map orig)` Return a new map of the same type as the given one with a copy of all contained key/value pairs.
`protected Constructor`	`findCopyConstructor(Class cls)` Find an appropriate copy constructor for the given type, or return null if none.
`protected Method`	`findGetter(Class type, Method setter)` Return the getter corresponding to the given setter, or null.
`protected serp.bytecode.BCClass`	`generateProxyBeanBytecode(Class type, boolean runtime)` Generate the bytecode for a bean proxy for the given type.
`protected serp.bytecode.BCClass`	`generateProxyCalendarBytecode(Class type, boolean runtime)` Generate the bytecode for a calendar proxy for the given type.
`protected serp.bytecode.BCClass`	`generateProxyCollectionBytecode(Class type, boolean runtime)` Generate the bytecode for a collection proxy for the given type.
`protected serp.bytecode.BCClass`	`generateProxyDateBytecode(Class type, boolean runtime)` Generate the bytecode for a date proxy for the given type.
`protected serp.bytecode.BCClass`	`generateProxyMapBytecode(Class type, boolean runtime)` Generate the bytecode for a map proxy for the given type.
`boolean`	`getAssertAllowedType()` Whether to perform runtime checks to ensure that all elements added to collection and map proxies are the proper element/key/value type as defined by the metadata.
`boolean`	`getTrackChanges()` Whether proxies produced by this factory will use `ChangeTracker`s to try to cut down on data store operations at the cost of some extra bookkeeping overhead.
`Collection`	`getUnproxyable()` Return a mutable view of class names we know cannot be proxied correctly by this manager.
`protected boolean`	`isOrdered(Class type)` Return whether the given collection type maintains an artificial ordering.
`protected boolean`	`isSetter(Method meth)` Return whether the given method is a setter.
`protected boolean`	`isUnproxyable(Class type)` Return whether the given type is known to be unproxyable.
`protected Class`	`loadBuildTimeProxy(Class type, ClassLoader loader)` Load the proxy class generated at build time for the given type, returning null if none exists.
`static void`	`main(String[] args)` Usage: java org.apache.openjpa.util.proxy.ProxyManagerImpl [option]* <class name>+ Where the following options are recognized: -utils/-u <number>: Generate proxies for the standard java.util collection, map, date, and calendar classes of the given Java version.
`Proxy`	`newCalendarProxy(Class type, TimeZone zone)` Return a new calendar proxy.
`Proxy`	`newCollectionProxy(Class type, Class elementType, Comparator compare)` Return a proxy for the given collection type.
`Proxy`	`newCustomProxy(Object orig)` Return a proxy for the given object, or null if this manager cannot proxy the object.
`Proxy`	`newDateProxy(Class type)` Return a new date proxy.
`Proxy`	`newMapProxy(Class type, Class keyType, Class elementType, Comparator compare)` Return a proxy for the given map type.
`void`	`setAssertAllowedType(boolean assertType)` Whether to perform runtime checks to ensure that all elements added to collection and map proxies are the proper element/key/value type as defined by the metadata.
`void`	`setTrackChanges(boolean track)` Whether proxies produced by this factory will use `ChangeTracker`s to try to cut down on data store operations at the cost of some extra bookkeeping overhead.
`void`	`setUnproxyable(String clsNames)` Provided for auto-configuration.
`protected Class`	`toProxyableCollectionType(Class type)` Return the concrete type for proxying.
`protected Class`	`toProxyableMapType(Class type)` Return the concrete type for proxying.

Method Detail

getTrackChanges

public boolean getTrackChanges()

Whether proxies produced by this factory will use ChangeTrackers to try to cut down on data store operations at the cost of some extra bookkeeping overhead. Defaults to true.

setTrackChanges

public void setTrackChanges(boolean track)

Whether proxies produced by this factory will use ChangeTrackers to try to cut down on data store operations at the cost of some extra bookkeeping overhead. Defaults to true.

getAssertAllowedType

public boolean getAssertAllowedType()

Whether to perform runtime checks to ensure that all elements added to collection and map proxies are the proper element/key/value type as defined by the metadata. Defaults to false.

setAssertAllowedType

public void setAssertAllowedType(boolean assertType)

Whether to perform runtime checks to ensure that all elements added to collection and map proxies are the proper element/key/value type as defined by the metadata. Defaults to false.

getUnproxyable

public Collection getUnproxyable()

Return a mutable view of class names we know cannot be proxied correctly by this manager.

setUnproxyable

public void setUnproxyable(String clsNames)

Provided for auto-configuration. Add the given semicolon-separated class names to the set of class names we know cannot be proxied correctly by this manager.
