Constructor Summary

Constructors

Modifier	Constructor and Description
	Jdk12Impl() Constructor used for creating 'real' instance; creates the shared data structs needed.
protected	Jdk12Impl(boolean dummy) Constructor derived classes call to avoid creation of helper Objects 'real' instance needs

Methods

Modifier and Type	Method and Description
java.util.List	getEmptyList()
java.util.Map	getEmptyMap()
java.util.Set	getEmptySet()
java.util.HashMap	getInsertOrderedMap() Alas, 1.2 doesn't have LinkedHashMap; only available from 1.4+, so let's just create a standard HashMap.
java.util.HashMap	getInsertOrderedMap(int initialSize) Alas, 1.2 doesn't have LinkedHashMap; only available from 1.4+, so let's just create a standard HashMap.
java.util.HashMap	getLRULimitMap(int maxSize) 1.2 doesn't have LinkedHashMap, so as usual, let's just create a HashMap
boolean	leakingThreadLocal() For 1.2, ThreadLocal actually does work correctly, although slowly (slow due to extra locking).
boolean	setInitCause(java.lang.Throwable newT, java.lang.Throwable rootT) Too bad it's only 1.4+ that can set the root cause...

Constructor derived classes call to avoid creation of helper Objects 'real' instance needs

Method Detail

leakingThreadLocal

public boolean leakingThreadLocal()

For 1.2, ThreadLocal actually does work correctly, although slowly (slow due to extra locking).

Specified by:

leakingThreadLocal in class JdkImpl

Returns:

True if using ThreadLocal is safe, and should not (in itself) be able to cause memory leaks; false if it is possible

getEmptyList

public java.util.List getEmptyList()

Specified by:

getEmptyList in class JdkImpl

getEmptyMap

public java.util.Map getEmptyMap()

Specified by:

getEmptyMap in class JdkImpl

getEmptySet

public java.util.Set getEmptySet()

Specified by:

getEmptySet in class JdkImpl

getInsertOrderedMap

public java.util.HashMap getInsertOrderedMap()

Alas, 1.2 doesn't have LinkedHashMap; only available from 1.4+, so let's just create a standard HashMap.

Specified by:

getInsertOrderedMap in class JdkImpl

getInsertOrderedMap

public java.util.HashMap getInsertOrderedMap(int initialSize)

Alas, 1.2 doesn't have LinkedHashMap; only available from 1.4+, so let's just create a standard HashMap.

Specified by:

getInsertOrderedMap in class JdkImpl

getLRULimitMap

public java.util.HashMap getLRULimitMap(int maxSize)

1.2 doesn't have LinkedHashMap, so as usual, let's just create a HashMap

Specified by:

getLRULimitMap in class JdkImpl

setInitCause

public boolean setInitCause(java.lang.Throwable newT,
                   java.lang.Throwable rootT)

Too bad it's only 1.4+ that can set the root cause...

Specified by:

setInitCause in class JdkImpl

Returns:

True if call succeeds, false if not.
