Constructors

Type Description
ArgumentParameterCollection

InnerPrimaryKey

The primary key needed to decide which specific row to alter with the current sql-command.

Declaration
protected abstract FieldInfo InnerPrimaryKey { get; }
Property Value
Type Description
FieldInfo

The actual value the primary key must have.

Declaration
protected abstract Parameter InnerPrimaryKeyValue { get; }

IsSentryIgnored

Get value indicating whether sentry is ignored on the current object for the current thread.

Declaration
public virtual bool IsSentryIgnored { get; }
Property Value
Type Description
Boolean

Methods

BeginIgnoreSentryCheck()

Starts the process of ignoring sentry on the object implementing the interface on the current thread.

Declaration
public virtual IgnoreSentryCheck BeginIgnoreSentryCheck()
Returns
Type Description
IgnoreSentryCheck

Disposable object that calls EndIgnoreSentryCheck() on Dispose.

CloneToBasicUpdatingQuery()

This partial implementation of Clone handles queries that are of SqlType Insert, Update or Delete. Depending on the type, you'll get back an Insert, Update or Delete object.

Declaration
public PrivateSave CloneToBasicUpdatingQuery()
Returns
Type Description
PrivateSave

Insert, Update or Delete object
Remarks

This implementation is based on the fact that HDB classes inherit the PrivateSave interface, without implementing it by actually BEING an Insert, Update or Delete. Simultaneously, we would like to treat them as the basic Insert, Update or Delete type (in cases where that is relevant).

This method will therefore create a new Insert, Update or Delete query, populate it with relevant data from itself, and return it as an object.

Exceptions
Type Condition
SoIllegalOperationException

You will get an exception if you pass in something that is not one of the three basic updating query types.

EndIgnoreSentryCheck()

Ends the process of ignoring sentry on the object implementing the interface on the current thread.

Declaration
public virtual void EndIgnoreSentryCheck()
