arlut.csd.Util.XMLNameValidator

public class XMLNameValidator
extends java.lang.Object

This is a dirt-simple XML Name validator for Ganymede, used to verify that proposed field names are acceptable for Ganymede's use. From the XML 1.1 (and XML 1.0 Version 5) standards: NameStartChar ::= ":" | [A-Z] | "_" | [a-z] | [#xC0-#xD6] | [#xD8-#xF6] | [#xF8-#x2FF] | [#x370-#x37D] | [#x37F-#x1FFF] | [#x200C-#x200D] | [#x2070-#x218F] | [#x2C00-#x2FEF] | [#x3001-#xD7FF] | [#xF900-#xFDCF] | [#xFDF0-#xFFFD] | [#x10000-#xEFFFF] NameChar ::= NameStartChar | "-" | "." | [0-9] | #xB7 | [#x0300-#x036F] | [#x203F-#x2040]

Method Detail

isValidNameStartChar

public static boolean isValidNameStartChar(int codePoint)

Returns true if codePoint is a valid character to start a name (element name or attribute name) in XML 1.1 or XML 1.0 (revision 5).

isValidNameChar

public static boolean isValidNameChar(int codePoint)

Returns true if codePoint is a valid character for a character after the first in a name (element name or attribute name) in XML 1.1 or XML 1.0 (revision 5).

isValidXMLName

public static boolean isValidXMLName(java.lang.String text)

Returns true if text is a valid name for element name or attribute name in XML 1.1 or XML 1.0 (revision 5)

isValidGanymedeName

public static boolean isValidGanymedeName(java.lang.String text)

Returns true if text can be used as a Ganymede object type or field name. Ganymede names differ from XML names in that underscores are not allowed (because they are used as the representation of spaces), and spaces are, after the first character in the name. We're also not going to permit colons to avoid confusion about XML namespaces.
