Constructor Detail

BaseSelectorContainer

public BaseSelectorContainer()

Default constructor.

Method Detail

hasSelectors

public boolean hasSelectors()

Indicates whether there are any selectors here.

Specified by:

hasSelectors in interface SelectorContainer

Returns:

true if there are selectors

selectorCount

public int selectorCount()

Gives the count of the number of selectors in this container

Specified by:

selectorCount in interface SelectorContainer

Returns:

the number of selectors

getSelectors

public FileSelector[] getSelectors(Project p)

Returns the set of selectors as an array.

Specified by:

getSelectors in interface SelectorContainer

Parameters:

p - the current project

Returns:

an array of selectors

selectorElements

public java.util.Enumeration selectorElements()

Returns an enumerator for accessing the set of selectors.

Specified by:

selectorElements in interface SelectorContainer

Returns:

an enumerator for the selectors

toString

public java.lang.String toString()

Convert the Selectors within this container to a string. This will just be a helper class for the subclasses that put their own name around the contents listed here.

Overrides:

toString in class DataType

Returns:

comma separated list of Selectors contained in this one

appendSelector

public void appendSelector(FileSelector selector)

Add a new selector into this container.

Specified by:

appendSelector in interface SelectorContainer

Parameters:

selector - the new selector to add

validate

public void validate()

This implementation validates the container by calling verifySettings() and then validates each contained selector provided that the selector implements the validate interface.

Ordinarily, this will validate all the elements of a selector container even if the isSelected() method of some elements is never called. This has two effects:

• Validation will often occur twice.
• Since it is not required that selectors derive from BaseSelector, there could be selectors in the container whose error conditions are not detected if their isSelected() call is never made.

Overrides:

validate in class BaseSelector

isSelected

public abstract boolean isSelected(java.io.File basedir,
                                   java.lang.String filename,
                                   java.io.File file)

Method that each selector will implement to create their selection behaviour. This is what makes SelectorContainer abstract.

Specified by:

isSelected in interface FileSelector

Specified by:

isSelected in class BaseSelector

Parameters:

basedir - the base directory the scan is being done from

filename - the name of the file to check

file - a java.io.File object for the filename that the selector can use

Returns:

whether the file should be selected or not
