Method Detail

getQueryCacheMap

public java.util.Map getQueryCacheMap()

INTERNAL Get the Map to store the query cache in

Specified by:

getQueryCacheMap in interface JDKPlatform

conformLike

public int conformLike(java.lang.Object left,
                       java.lang.Object right)

INTERNAL: An implementation of in memory queries with Like which uses the JDK 1.4 regular expression framework.

Specified by:

conformLike in interface JDKPlatform

getTimeInMillis

public long getTimeInMillis(java.util.Calendar calendar)

INTERNAL: Get the milliseconds from a Calendar. In JDK 1.4, this can be accessed directly from the calendar.

Specified by:

getTimeInMillis in interface JDKPlatform

setTimeInMillis

public void setTimeInMillis(java.util.Calendar calendar,
                            long millis)

INTERNAL: Set the milliseconds for a Calendar. In JDK 1.4, this can be set directly in the calendar.

Specified by:

setTimeInMillis in interface JDKPlatform

setExceptionCause

public void setExceptionCause(java.lang.Throwable exception,
                              java.lang.Throwable cause)

INTERNAL: Use API first available in JDK 1.4 to set the cause of an exception.

Specified by:

setExceptionCause in interface JDKPlatform

shouldPrintInternalException

public boolean shouldPrintInternalException()

INTERNAL return a boolean which determines where TopLink should include the TopLink-stored Internal exception in it's stack trace. For JDK 1.4 VMs with exception chaining the Internal exception can be redundant and confusing.

Specified by:

shouldPrintInternalException in interface JDKPlatform

Returns:

boolean will return false since JDK 1.4 does supports exception chaining
