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:
whether any selectors are in this container

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 in this container

getSelectors


public FileSelector[] getSelectors(Project p)
Returns the set of selectors as an array.

Specified by:
getSelectors in interface SelectorContainer
Returns:
an array of selectors in this container

selectorElements


public java.util.Enumeration selectorElements()
Returns an enumerator for accessing the set of selectors.

Specified by:
selectorElements in interface SelectorContainer
Returns:
an enumerator that goes through each of 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 java.lang.Object
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
Returns:
the selector that was added

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

addSelector


public void addSelector(SelectSelector selector)
add a "Select" selector entry on the selector list

Specified by:
addSelector in interface SelectorContainer

addAnd


public void addAnd(AndSelector selector)

addAnd in interface SelectorContainer

addOr


public void addOr(OrSelector selector)

Specified by:
addOr in interface SelectorContainer

addNot


public void addNot(NotSelector selector)

Specified by:
addNot in interface SelectorContainer

addNone


public void addNone(NoneSelector selector)
add a "None" selector entry on the selector list

Specified by:
addNone in interface SelectorContainer

addMajority
