Class JDBCCMP1xFieldBridge

java.lang.Object

org.jboss.as.cmp.jdbc.bridge.JDBCAbstractCMPFieldBridge

org.jboss.as.cmp.jdbc.bridge.JDBCCMP1xFieldBridge

All Implemented Interfaces:

CMPFieldBridge, FieldBridge, JDBCCMPFieldBridge, JDBCFieldBridge

public class JDBCCMP1xFieldBridge
extends JDBCAbstractCMPFieldBridge

JDBCCMP1xFieldBridge is a concrete implementation of JDBCCMPFieldBridge for CMP version 1.x. Getting and setting of instance fields set the corresponding field in bean instance. Dirty checking is performed by storing the current value in the entity persistence context when ever setClean is called, and comparing current value to the original value.

Life-cycle: Tied to the EntityBridge.

Multiplicity: One for each entity bean cmp field.

Method Detail

getInstanceValue

public Object getInstanceValue(CmpEntityBeanContext ctx)

Description copied from interface: JDBCFieldBridge

Gets the internal value of this field without user level checks.

Parameters:

ctx - the context for which this field's value should be fetched

Returns:

the value of this field

setInstanceValue

public void setInstanceValue(CmpEntityBeanContext ctx,
                    Object value)

Description copied from interface: JDBCFieldBridge

Sets the internal value of this field without user level checks.

Parameters:

ctx - the context for which this field's value should be set

value - the new value of this field

getLockedValue

public Object getLockedValue(CmpEntityBeanContext ctx)

Parameters:

ctx - instance's context

Returns:

field value that was locked.

lockInstanceValue

public void lockInstanceValue(CmpEntityBeanContext ctx)

Description copied from interface: JDBCCMPFieldBridge

Optimistically locks field value.

isLoaded

public boolean isLoaded(CmpEntityBeanContext ctx)

Description copied from interface: JDBCFieldBridge

Has the data been loaded?

isDirty

public boolean isDirty(CmpEntityBeanContext ctx)

Has the value of this field changes since the last time clean was called.

setClean

public void setClean(CmpEntityBeanContext ctx)

Mark this field as clean. Saves the current state in context, so it can be compared when isDirty is called.

isReadTimedOut

public boolean isReadTimedOut(CmpEntityBeanContext ctx)

Description copied from interface: JDBCFieldBridge

Has current data read timed out?

resetPersistenceContext

public void resetPersistenceContext(CmpEntityBeanContext ctx)

Description copied from interface: JDBCFieldBridge

Resets any persistence data maintained in the context.

Specified by:

resetPersistenceContext in interface JDBCFieldBridge

Specified by:

resetPersistenceContext in class JDBCAbstractCMPFieldBridge

setDirtyAfterGet

protected void setDirtyAfterGet(CmpEntityBeanContext ctx)

Specified by:

setDirtyAfterGet in class JDBCAbstractCMPFieldBridge
