Constructor Detail

FilterItemListToSimpleList

public FilterItemListToSimpleList(java.util.List listOfFilterItems,
                                  FilterItemListInterface filterItemList,
                                  boolean enforceAsAllSameType,
                                  FilterObjectFactoryInterface filterObjectFactory)

Constructs a new simple list from the given parameters.

Parameters:

listOfFilterItems - the list of native model filter items to process

filterItemList - the list of items in the filter model

enforceAsAllSameType - flag for restricting logical conditions

filterObjectFactory - the object factory used during conversions between the filter model and native model

Method Detail

getFilterLogicList

public FilterLogicListInterface getFilterLogicList()

Returns the filter logic list. This list contains all the test nodes in the filter and is represented as a single, simple list.

Returns:

the filter logic list

commitChanges

public boolean commitChanges()

Commits any changes in the filter model to the underlying native model.

Specified by:

commitChanges in interface SimpleLogicListInterface

Specified by:

commitChanges in class AbstractFilterItemSimpleListBase

Returns:

true if the native model was successfully updated, false otherwise

getRootFilterObject

public java.lang.Object getRootFilterObject()

Returns the native filter object.

Specified by:

getRootFilterObject in interface SimpleLogicListInterface

Specified by:

getRootFilterObject in class AbstractFilterItemSimpleListBase

Returns:

the native filter object

setTestNodeAt

protected java.lang.Object setTestNodeAt(int index,
                                         FilterLogicTestNodeInterface testNode)

Assigns the given test node at the specified location in the list.

Overrides:

setTestNodeAt in class AbstractFilterItemSimpleListBase

Parameters:

index - the index in the list to assign the test node

testNode - the test node to assign to the list

Returns:

the test node previously occupying the specified index in the list

removeTestNodeAt

protected java.lang.Object removeTestNodeAt(int index)

Removes and returns the test node at the specified index in the list.

Overrides:

removeTestNodeAt in class AbstractFilterItemSimpleListBase

Parameters:

index - the index in the list of the target test node

Returns:

the test node that was removed from the list

addTestNodeAt

protected void addTestNodeAt(int index,
                             FilterLogicTestNodeInterface testNode)

Adds the given test node at the specified location in the list.

Overrides:

addTestNodeAt in class AbstractFilterItemSimpleListBase

Parameters:

index - the index in the list to add the test node

testNode - the test node to assign to the list

getTestNodeAt
