Method Detail

getItems

java.util.List getItems()

Return a list of criteria items. Each item within a row should have a unique name. An item can contain multiple operators and values.

Returns:

The list of criteria items that make up this row.

createSimpleItem

SimpleItem createSimpleItem(java.lang.String name)

Create a simple criteria item that does not consist of a nested row. It can be added to a simple criteria row later.

Parameters:

name - The name of the criteria item to be created.

Returns:

The newly created simple criteria item.

createNestedRowItem

NestedRowItem createNestedRowItem(java.lang.String name,
                                  SimpleRow nestedRow)

Create a nested row criteria item. It can be added to a simple criteria row later.

Parameters:

nestedRow - The criteria row to be nested in the nested item.

Returns:

The newly created nested row criteria item.

addItem

void addItem(Item item)

For design time tool to add a new criteria item to this row.

Parameters:

item - The criteria item to be added to this row.

removeItem

boolean removeItem(java.lang.String itemName)

Remove an item from the row.

Parameters:

itemName - Name of the item to be removed.

Returns:

True if the item is removed sucessfully. False if no item can be found with the given name, or the item cannot be removed, for example, if this row belongs to a predefined criteria provided by the datacontrol.

supportsSubSelectItem

boolean supportsSubSelectItem()

Whether subselect view criteria item is supported. A subselect criteria item contains a nested criteria as its value.

Returns:

true if subselect criteria item is supported.

supportsNestedRowItem

boolean supportsNestedRowItem()

Whether nested row criteria item is supported. A nested row criteria item contains a nested criteria row in the same accessor.

Returns:

true if nested row criteria item is supported. false otherwise.

supportsExpressionAsItemName

boolean supportsExpressionAsItemName()

Whether an expression can be specified as the name of a criteria item. Usually the name would be the name of an attribute.
