Class AttributeEditorProperties

java.lang.Object
  com.tensegrity.gui.component.AttributeEditorProperties

All Implemented Interfaces:

java.util.EventListener, java.beans.PropertyChangeListener

public class AttributeEditorProperties

extends java.lang.Object

implements java.beans.PropertyChangeListener

The AttributeEditorProperties class maintains the properties of an AttributeTable, such as hidden Attributes and Enumerations. Use the methods of this class to determine whether Attributes should be hidden, mark certain attributes to be hidden, retrieve all predefined enumerations or store newly created ones. Basically this class encapsulates a simple properties file.

This class is usually created by the AttributeEditor itself and can then be retrieved by calling the AttributeEditor.getEditorProperties() method.

This class is used to set up the behavior of an AttributeEditor. It controls the sorting, visibility and mutability of attributes. It also contains a map of generic settings that can be freely defined by an AttributeEditor implementation. All settings are stored in a properties file if persistence is not deactivated (e.g. by calling the constructor with null as the filename value).

An AttributeEditor using this class may support the following configuration settings listed in the constants. Implementations of the AttributeEditor interface should list the supported properties in the JavaDoc.

• PROPERTYNAME_SHOWCATEGORIES
• PROPERTYNAME_USEEXACTMATCHING
• PROPERTYNAME_AUTOEXPANDCATEGORIES
• PROPERTYNAME_RENAMINGALLOWED
• PROPERTYNAME_ENABLE_WRITEPROTECTION
• PROPERTYNAME_MERGEELEMENTTYPES
• PROPERTYNAME_DYNAMICROWHEIGHT

The visibility of an Attribute can be queried and set by calling the following methods.

• boolean isVisible(String)
• void setVisible(String, boolean)

The mutability of an Attribute can be queried and set by calling the following methods.

Note: You should not make an Attribute mutable in the editor if it has been returned immutable from the AttributableOnSet.

• boolean isMutable(String)
• void setMutable(String, boolean)

The following methods control the persistence of the properties and other configurations stored in an AttributeEditorProperties instance:

• void readProperties()
• void writeProperties()
• void enablePropertyPersistence()
• void disablePropertyPersistence()
• boolean isPropertyPersistenceEnabled()

It is possible to specify new attribute display names with the following methods:

• String getName(String)
• void renameAttribute(String, String)

The following methods can be used to retrieve or set the properties that define the AttributeEditor behavior. Which properties are supported depends on the AttributeEditor that is used. A basic list of properties is shown in the usage documentation.

• Object getPropery(String)
• void setProperty(String, Object)
• void assertProperty(String, Object)
• boolean getBoolean(String, boolean)

To manage the sort order in the AttributeEditor you should use these methods:

• int getSortMode()
• void setSortMode(int)
• Comparator getSortComparator()

addFilter

public void addFilter(java.lang.String filter)

Adds a filter to the list that is used to determine the visibility of attributes. The filter can contain the wildcards '*' and '?' and works like a filename pattern. The whole pathname of an attribute is matched against it. It at least one filter is added, only matching attributes are shown. You can remove the entries by using removeFilter(String) or clearFilters().

Parameters:

filter - The filter string to add

See Also:

removeFilter(String), clearFilters(), checkAgainstFilters(String)

Parameters:

filter - the filter to remove

See Also:

addFilter(String), clearFilters(), checkAgainstFilters(String)

Returns:

true, if the visibility is determined using a list of filters.

checkAgainstFilters

public boolean checkAgainstFilters(java.lang.String attributePath)

Checks if an attribute should be visible in the editor according to the list of filters. The method will return true if the list is empty or the given pathname matches any of the patterns in the list. To make it possible to add filters for attributes in specific sets or in all sets another wildcard '**' has been added which means a 'random number of path elements'. e.g. "**:a*" -> matches all attributes starting with a lowercase 'a' in all categories "**:Geometry:**" -> matches all attributes below the category 'Geometry' "RectangleNode:**:Custom:**" -> matches all attributes below 'Custom' in the set with the root 'RectangleNode' "RectangleNode:**" -> matches all attributes under the root 'RectangleNode' "RectangleNode:*" -> matches all attributes DIRECTLY under the root 'RectangleNode'

Returns:

true if the list is empty or the given pathname matches any of the patterns in the list

Returns:

boolean flag that indicates whether settings are stored into a file or not

Find more information in the class documentation

enablePropertyPersistence

public void enablePropertyPersistence()

Enables property persistence. This means that the settings of the AttributeEditorProperties are automatically stored inside a file.

Find more information in the class documentation
