Constructor Detail

SymbolSelectorListModel

public SymbolSelectorListModel(java.io.File dir,
                               SelectorFilter filter,
                               java.lang.String fileExtension)

Creates a new instance of the model for the list in the Symbol Selector window where the symbols are stored in the dir (root directory) param.

The filter is a user defined filter used to know which elements in the folder are accepted or rejected for this list and it is used to avoid mixing marker symbols for polygons for example.

fileExtension param defines the extension of the file to be parsed. This is like that to enable inheritance of this class to other file selector such as StyleSelector.

Parameters:

dir - , the root dir where symbols are located.

filter - , the filter used to show or hide some elements.

fileExtension - , file extension used for the files to be parsed.

Method Detail

dispose

public void dispose()

Description copied from interface: Disposable

Disposes the current object, to allow it to close and dispose any used resources.

NOTE:After calling this method, the object may not be usable anymore.

Specified by:

dispose in interface Disposable

remove

public java.lang.Object remove(int i)
                        throws java.lang.ArrayIndexOutOfBoundsException

Description copied from interface: ListModel

Removes the element at the specified position in this Vector. shifts any subsequent elements to the left (subtracts one from their indices). Returns the element that was removed from the Vector.

Parameters:

i - Índice del elemento que se quiere eliminar

Returns:

Objeto eliminado

Throws:

java.lang.ArrayIndexOutOfBoundsException - Si el índice está fuera del array

insertAt

public void insertAt(int i,
                     java.lang.Object o)

Description copied from interface: ListModel

Inserts the specified element at the specified position in this Vector. Shifts the element currently at that position (if any) and any subsequent elements to the right (adds one to their indices).

Parameters:

i - index at which the specified element is to be inserted.

o - element to be inserted.

accepts

protected boolean accepts(ISymbol symbol)

add

public void add(java.lang.Object o)

Description copied from interface: ListModel

Appends the specified element to the end of this Vector

Parameters:

o - element to be appended to this Vector

getObjects

public java.util.Vector<ISymbol> getObjects()

Description copied from interface: ListModel

Obtains the objects that are in the model

Returns:

Vector with the objetos

getSize

public int getSize()

Specified by:

getSize in interface javax.swing.ListModel

getElementAt

public java.lang.Object getElementAt(int index)

Specified by:

getElementAt in interface javax.swing.ListModel
