VirtualRelvar

public VirtualRelvar()

Creates an empty VirtualRelvar

VirtualRelvar

@AttributeDef(attributeName="SP_EXPRESSION",requiresEscaping=true,typeName="STRING") @AttributeDef(attributeName="RELVARNAME",requiresEscaping=false,typeName="NAME")
public VirtualRelvar(java.lang.String relvarName,
                                                                                                                                                                                           java.lang.String expressionText)

Creates the VirtualRelvar

Parameters:

relvarName - The name for the virtual relvar

expressionText - The expressionText

Method Detail

getExpressionText

@GetterMethod(attributeDefs=@AttributeDef(attributeName="SP_EXPRESSION",requiresEscaping=true,typeName="STRING"),
              relvarNames="VIRTUALRELVAR")
public final java.lang.String getExpressionText()

Gets The expressionText

Returns:

The expressionText.

getPreUpdateState

public final UpdatableDBObject getPreUpdateState()

Description copied from interface: UpdatableDBObject

Gets The state of the object as it was built by the J/R bridging engine immediately after the object was created from a database tuple (and which should have been set by/using the setPreUpdateState() method.

Returns:

The state of the object as it was built by the J/R bridging engine immediately after the object was created from a database tuple (and which should have been set by/using the setPreUpdateState() method.

getRelvarName

@GetterMethod(attributeDefs=@AttributeDef(attributeName="RELVARNAME",requiresEscaping=false,typeName="NAME"),
              relvarNames="VIRTUALRELVAR")
public final java.lang.String getRelvarName()

Gets The name for the virtual relvar

Returns:

The name for the virtual relvar.

setExpressionText

public final void setExpressionText(java.lang.String expression)

Sets The expression

Parameters:

expression - The expression to set.

setExpressionText

@AttributeDef(attributeName="SP_EXPRESSION",
              requiresEscaping=true,
              typeName="STRING")
public final void setExpressionText(ValueBuffer expressionText)

Sets The expression

Parameters:

expressionText - The expressionText to set.

setPreUpdateState

public final void setPreUpdateState()

Description copied from interface: UpdatableDBObject

This method is called by the J/R bridging engine after an object has been setup from some tuple retrieved from the database. The method must cause the object to save a copy (/clone) of all the fields that are pertinent to the database. This copy will be retrieved by the J/R bridging engine using the getPreUpdateState() method call, and will subsequently be used by the J/R bridging engine to determine which fields have changed value, and thus to determine which attributes need to be updated in the database.

setRelvarName

public final void setRelvarName(java.lang.String relvarName)

Sets The name for the virtual relvar

Parameters:

relvarName - The relvarName to set.

setRelvarName

@AttributeDef(attributeName="SP_EXPRESSION",
              requiresEscaping=true,
              typeName="STRING")
public final void setRelvarName(ValueBuffer relvarName)

Sets The name for the virtual relvar

Parameters:

relvarName - The relvarName to set.
