Class JdkImpl
java.lang.Object
com.ctc.wstx.compat.JdkImpl
- Direct Known Subclasses:
- Jdk12Impl
public abstract class JdkImpl
- extends java.lang.Object
This is the interface used to access JDK-dependant functionality; generally
things that later JDKs have in their APIs, but that can be simulated
with earlier JDKs to some degree.

protected JdkImpl()
leakingThreadLocal
public abstract boolean leakingThreadLocal()
- This method is used to check whether GC-friendly caching can be
implemented using
ThreadLocal
. Some JDKs (notably,
JDK 1.3.x) have possibility for memory leaks, and when running on
them, such caching should not be used.
- Returns:
- True if using ThreadLocal is safe, and should not (in itself)
be able to cause memory leaks; false if it is possible

setInitCause
public abstract boolean setInitCause(java.lang.Throwable newT,
java.lang.Throwable rootT)
- Method that sets init cause of the specified Throwable to be
another specified Throwable. Note: not all JDKs support such
functionality.
- Returns:
- True if call succeeds, false if not.
