Method Detail

parse

public java.lang.Object parse(java.lang.Object value)
                       throws java.lang.IllegalArgumentException

Description copied from interface: AttributeType

Allows this AttributeType to convert an argument to its prefered storage type. If no parsing is possible, returns the original value. If a parse is attempted, yet fails (i.e. a poor decimal format) throw the Exception. This is mostly for use internally in Features, but implementors should simply follow the rules to be safe.

Specified by:

parse in interface AttributeType

Overrides:

parse in class DefaultAttributeType

Parameters:

value - the object to attempt parsing of.

Returns:

value converted to the preferred storage of this AttributeType. If no parsing was possible then the same object is returned.

Throws:

java.lang.IllegalArgumentException - if parsing is attempted and is unsuccessful.

duplicate

public java.lang.Object duplicate(java.lang.Object o)

Duplicate as a String

Specified by:

duplicate in interface AttributeType

Overrides:

duplicate in class DefaultAttributeType

Parameters:

o - DOCUMENT ME!

Returns:

a String obtained by calling toString or null.

getRestriction

public Filter getRestriction()

Description copied from interface: PrimativeAttributeType

This provides access to the immutable restriction for this attribute type. This restriction should be applied when real data hits instances of this class. This mapps to the idea of a Facet in xml schema, or restrictions in a database. Examples may include Length <= 20 (VARCHAR 20) The Default value is Filter.ALL

Specified by:

getRestriction in interface PrimativeAttributeType

Overrides:

getRestriction in class DefaultAttributeType
