Method Detail

supportsCustomEditor

public boolean supportsCustomEditor()

Specified by:

supportsCustomEditor in interface PropertyEditor

Overrides:

supportsCustomEditor in class PropertyEditorSupport

getCustomEditor

public Component getCustomEditor()

Specified by:

getCustomEditor in interface PropertyEditor

Overrides:

getCustomEditor in class PropertyEditorSupport

getXMLValueTag

protected String getXMLValueTag()

Provides name of XML tag to use for XML persistence of the property value

attachEnv

public void attachEnv(PropertyEnv env)

Specified by:

attachEnv in interface ExPropertyEditor

getJavaInitializationString

public String getJavaInitializationString()

This method is intended for use when generating Java code to set the value of the property. It should return a fragment of Java code that can be used to initialize a variable with the current property value.

Example results are "2", "new Color(127,127,34)", "Color.orange", etc.

Specified by:

getJavaInitializationString in interface PropertyEditor

Overrides:

getJavaInitializationString in class PropertyEditorSupport

Returns:

A fragment of Java code representing an initializer for the current value.

getAsText

public String getAsText()

Specified by:

getAsText in interface PropertyEditor

Overrides:

getAsText in class PropertyEditorSupport

Returns:

The property value as a human editable string.

Returns null if the value can't be expressed as an editable string.

If a non-null value is returned, then the PropertyEditor should be prepared to parse that string back in setAsText().

setAsText

public void setAsText(String text)
               throws IllegalArgumentException

Set the property value by parsing a given String. May raise java.lang.IllegalArgumentException if either the String is badly formatted or if this kind of property can't be expressed as text.

Specified by:

setAsText in interface PropertyEditor

Overrides:

setAsText in class PropertyEditorSupport

Parameters:

text - The string to be parsed.

Throws:

IllegalArgumentException

readFromXML

public void readFromXML(Node element)
                 throws IOException

Called to load property value from specified XML subtree. If succesfully loaded, the value should be available via the getValue method. An IOException should be thrown when the value cannot be restored from the specified XML element

Specified by:

readFromXML in interface XMLPropertyEditor

Parameters:

element - the XML DOM element representing a subtree of XML from which the value should be loaded

Throws:

IOException - thrown when the value cannot be restored from the specified XML element

storeToXML

public Node storeToXML(Document doc)

Called to store current property value into XML subtree. The property value should be set using the setValue method prior to calling this method.

Specified by:

storeToXML in interface XMLPropertyEditor

Parameters:

doc - The XML document to store the XML in - should be used for creating nodes only

Returns:

the XML DOM element representing a subtree of XML from which the value should be loaded
