getTagAttributeDescriptors

public TagAttributeDescriptor[] getTagAttributeDescriptors()

Description copied from interface: TagConverter

Returns the list of TagAttributeDescriptors which are used by this converter. Each TagAttributeDescriptor describes an attribute which can be used by this TagConverter. Attributes can be optional and they can also be automatic. An automatic attribute implies the use of this converter if that attribute appears in the tag (e.g. date=".." implies the use of the DateTagConverter).

Specified by:

getTagAttributeDescriptors in interface TagConverter

getName

public java.lang.String getName()

Description copied from interface: TagConverter

Returns the unique name for the TagConverter. This name can be used by the TagConverterManager to get a handle to this converter. When you specify the use of a TagConverter using the converter attribute in a tag, you use this name to refer to the TagConverter. TagConverter names are case insensitive (as is the convention in HTML).
