Class decimal.PrecisionResetter

java.lang.Object

com.goldencode.p2j.util.decimal.PrecisionResetter

All Implemented Interfaces:

Finalizable

Enclosing class:

decimal

private class decimal.PrecisionResetter
extends java.lang.Object
implements Finalizable

Helper to reset the associated instance's precision to a prior value based on a notification that a particular scope has exited. This scope notification support is provided by TransactionManager.registerFinalizable(com.goldencode.p2j.util.Finalizable, boolean) and the Finalizable interface.

Field Detail

oldPrecision

int oldPrecision

The precision to which the containing instance will be reset.

Constructor Detail

PrecisionResetter

PrecisionResetter(int oldPrecision)

Construct an instance which can reset the containing instance's precision when a notification is received. See decimal.setTemporaryPrecision(int).

Parameters:

oldPrecision - The precision to which the containing instance must be reset.

Method Detail

finished

public void finished()

Processes the end of scope notification and resets the associated instance's precision. This notification is provided by the TransactionManager.

Specified by:

finished in interface Finalizable

deleted

public void deleted()

Provides a notification that the external program scope in which the object is registered is is being deleted and the object's reference will be lost after this method is called.

This is a no-op in this case.

Specified by:

deleted in interface Finalizable

iterate

public void iterate()

Processes the iterate notification provided by the TransactionManager. This implementation does nothing.

Specified by:

iterate in interface Finalizable

retry

public void retry()

Processes the retry notification provided by the TransactionManager. This implementation does nothing.

Specified by:

retry in interface Finalizable
