Constant Field Values

MV_PROPERTY_WARN_THRESHOLD

public static final int MV_PROPERTY_WARN_THRESHOLD

See Also:

Constant Field Values

SAVE_SESSION

public static final boolean SAVE_SESSION

The value of this flag determines the behaviour of save(). If false, save will throw a UnsupportedRepositoryOperationException if the sub tree rooted at this item does not contain all transient changes. If true, save will delegate to Session.save().

perform

@CheckForNull
protected final <U> U perform(@Nonnull
                                           SessionOperation<U> op)

Perform the passed SessionOperation.

Type Parameters:

U - return type of the operation

Parameters:

op - operation to perform

Returns:

the result of op.perform()

Throws:

javax.jcr.RepositoryException - as thrown by op.perform().

safePerform

@CheckForNull

Perform the passed SessionOperation assuming it does not throw an RepositoryException. If it does, wrap it into and throw it as a RuntimeException.

Type Parameters:

U - return type of the operation

Parameters:

op - operation to perform

Returns:

the result of op.perform()

               throws javax.jcr.RepositoryException

Specified by:

getName in interface javax.jcr.Item

Throws:

javax.jcr.RepositoryException

See Also:

Item.getName()

public String getPath()
               throws javax.jcr.RepositoryException

Specified by:

getPath in interface javax.jcr.Item

Specified by:

save in interface javax.jcr.Item

javax.jcr.RepositoryException

Item.save()
