Method Detail

getAttValue

public String getAttValue()

setAttValue

public void setAttValue(String attValue)

getAttName

public String getAttName()

setAttName

public void setAttName(String attName)

getPossibleAttributeNames

public static Set getPossibleAttributeNames()

getPossibleAttributeValueSet

public static Set getPossibleAttributeValueSet(String attributeName)

Returns the set of possible values for the named attribute. These values are DTD-allowed values for the XML-attribute

value

for the indicated element.

getPossibleAttributeValueList

public static List getPossibleAttributeValueList(String attributeName)

readMDAttributesIN

public static Iterator readMDAttributesIN(OJElement elt)

Returns an iterator on all attributes of the given item, possibly taking

metadata

and

extradata

before. The resulting iterator returns MDAttribute objects.

Parameters:

elt -

Returns:

an iterator of String[] {attribute-name, attribute-value}

computeValueListCenteredAt

public static List computeValueListCenteredAt(String attName,
                                              String value)

Computes an ordered list of the possible values for this attribute-name centered at the value. That is whose first item is the value, followed by the one first below then the one above, then the one second below...

Parameters:

attName -

value -

Returns:

getMDAttributes

public static List getMDAttributes(OJElement elt)

Returns:

List of MDAttributes contained in elt

toString

public String toString()

Overrides:

toString in class Object
