Constructor Details

DatatypeAttribute

public DatatypeAttribute(QName qname,
 com.sun.msv.datatype.xsd.XSDatatype datatype)

DatatypeAttribute

public DatatypeAttribute(QName qname,
 com.sun.msv.datatype.xsd.XSDatatype datatype,
 String text)

Method Details

toString

public String toString()

Overrides:

toString in class AbstractAttribute

getXSDatatype

public com.sun.msv.datatype.xsd.XSDatatype getXSDatatype()

Returns the MSV XSDatatype for this node

Returns:

DOCUMENT ME!

getNamespacePrefix

public String getNamespacePrefix(String uri)

Specified by:

getNamespacePrefix in interface com.sun.msv.datatype.SerializationContext

getBaseUri

public String getBaseUri()

Specified by:

getBaseUri in interface org.relaxng.datatype.ValidationContext

isNotation

public boolean isNotation(String notationName)

Specified by:

isNotation in interface org.relaxng.datatype.ValidationContext

isUnparsedEntity

public boolean isUnparsedEntity(String entityName)

Specified by:

isUnparsedEntity in interface org.relaxng.datatype.ValidationContext

resolveNamespacePrefix

public String resolveNamespacePrefix(String prefix)

Specified by:

resolveNamespacePrefix in interface org.relaxng.datatype.ValidationContext

getQName

public QName getQName()

Description copied from interface: Attribute

Returns the QName of this attribute which represents the local name, the qualified name and the Namespace.

Specified by:

getQName in interface Attribute

Returns:

the QName associated with this attribute

getValue

public String getValue()

Description copied from interface: Attribute

Returns the value of the attribute. This method returns the same value as the Node.getText()method.

Specified by:

getValue in interface Attribute

Returns:

the value of the attribute

setValue

public void setValue(String value)

Description copied from interface: Attribute

Sets the value of this attribute or this method will throw an UnsupportedOperationException if it is read-only.

Specified by:

setValue in interface Attribute

Overrides:

setValue in class AbstractAttribute

Parameters:

value - is the new value of this attribute

getData

public Object getData()

Description copied from interface: Attribute

Accesses the data of this attribute which may implement data typing bindings such as XML Schema or Java Bean bindings or will return the same value as Node.getText().

Specified by:

getData in interface Attribute

Overrides:

getData in class AbstractAttribute

Returns:

the attribute data

setData

public void setData(Object data)

Description copied from interface: Attribute

Sets the data value of this attribute if this element supports data binding or calls Node.setText(String)if it doesn't.

Specified by:

setData in interface Attribute

Overrides:

setData in class AbstractAttribute

Parameters:

data - the attribute data

getParent

public Element getParent()

Description copied from interface: Node

getParent returns the parent Element if this node supports the parent relationship or null if it is the root element or does not support the parent relationship.

This method is an optional feature and may not be supported for all Node implementations.

Specified by:

getParent in interface Node

Overrides:

getParent in class AbstractNode

Returns:

the parent of this node or null if it is the root of the tree or the parent relationship is not supported.

setParent

public void setParent(Element parent)

Description copied from interface: Node

setParent sets the parent relationship of this node if the parent relationship is supported or does nothing if the parent relationship is not supported.

This method should only be called from inside an Element implementation method and is not intended for general use.

Specified by:

setParent in interface Node

Overrides:

setParent in class AbstractNode

Parameters:

parent - is the new parent of this node.

supportsParent

public boolean supportsParent()

Description copied from interface: Node

supportsParent returns true if this node supports the parent relationship.

Some XML tree implementations are singly linked and only support downward navigation through children relationships. The default case is that both parent and children relationships are supported though for memory and performance reasons the parent relationship may not be supported.

Specified by:

supportsParent in interface Node

Overrides:

supportsParent in class AbstractNode

Returns:

true if this node supports the parent relationship or false it is not supported

isReadOnly

public boolean isReadOnly()

Description copied from interface: Node

isReadOnly returns true if this node is read only and cannot be modified. Any attempt to modify a read-only Node will result in an UnsupportedOperationException being thrown.

Specified by:

isReadOnly in interface Node

Overrides:

isReadOnly in class AbstractNode

Returns:

true if this Node is read only and cannot be modified otherwise false.

validate

protected void validate(String txt)
                 throws IllegalArgumentException

Throws:

IllegalArgumentException

convertToValue

protected Object convertToValue(String txt)
