TinyAttributeImpl

public TinyAttributeImpl(TinyDocumentImpl doc,
                         int nodeNr)

Method Detail

getParent

public NodeInfo getParent()

Get the parent node

Specified by:

getParent in interface NodeInfo

Overrides:

getParent in class TinyNodeImpl

Returns:

The Node object describing the containing element or root node.

getSequenceNumber

protected long getSequenceNumber()

Get the node sequence number (in document order). Sequence numbers are monotonic but not consecutive. In the current implementation, parent nodes (elements and roots) have a zero least-significant word, while namespaces, attributes, text nodes, comments, and PIs have the top word the same as their owner and the bottom half reflecting their relative position.

Overrides:

getSequenceNumber in class TinyNodeImpl

getNodeType

public final short getNodeType()

Return the type of node.

Specified by:

getNodeType in interface NodeInfo

Specified by:

getNodeType in interface org.w3c.dom.Node

Returns:

Node.ATTRIBUTE

getStringValue

public java.lang.String getStringValue()

Return the character value of the node.

Specified by:

getStringValue in interface NodeInfo

Returns:

the attribute value

getFingerprint

public int getFingerprint()

Get the fingerprint of the node, used for matching names

Specified by:

getFingerprint in interface NodeInfo

Overrides:

getFingerprint in class TinyNodeImpl

getNameCode

public int getNameCode()

Get the name code of the node, used for finding names in the name pool

Specified by:

getNameCode in interface NodeInfo

Overrides:

getNameCode in class TinyNodeImpl

See Also:

allocate, getFingerprint

getPrefix

public java.lang.String getPrefix()

Get the prefix part of the name of this node. This is the name before the ":" if any.

Specified by:

getPrefix in interface NodeInfo

Specified by:

getPrefix in interface org.w3c.dom.Node

Overrides:

getPrefix in class TinyNodeImpl

Returns:

the prefix part of the name. For an unnamed node, return null.

getDisplayName

public java.lang.String getDisplayName()

Get the display name of this node. For elements and attributes this is [prefix:]localname. For unnamed nodes, it is an empty string.

Specified by:

getDisplayName in interface NodeInfo

Overrides:

getDisplayName in class TinyNodeImpl

Returns:

The display name of this node. For a node with no name, return an empty string.

getLocalName

public java.lang.String getLocalName()

Get the local name of this node.

Specified by:

getLocalName in interface NodeInfo

Specified by:

getLocalName in interface org.w3c.dom.Node

Overrides:

getLocalName in class TinyNodeImpl

Returns:

The local name of this node. For a node with no name, return an empty string.

getURI

public final java.lang.String getURI()

Get the URI part of the name of this node.

Specified by:

getURI in interface NodeInfo

Overrides:

getURI in class TinyNodeImpl

Returns:

The URI of the namespace of this node. For the default namespace, return an empty string

generateId

public java.lang.String generateId()

Generate id. Returns key of owning element with the attribute name as a suffix

Specified by:

generateId in interface NodeInfo

Overrides:

generateId in class TinyNodeImpl

Returns:

a string.

copy

public void copy(Outputter out)
          throws javax.xml.transform.TransformerException

Copy this node to a given outputter

Specified by:

copy in interface NodeInfo

Throws:

javax.xml.transform.TransformerException

getLineNumber

public int getLineNumber()

Get the line number of the node within its source document entity

Specified by:

getLineNumber in interface NodeInfo

Specified by:

getLineNumber in interface javax.xml.transform.SourceLocator

Overrides:

getLineNumber in class TinyNodeImpl

Returns:

the line number of the node in its original source document; or -1 if not available

getSchemaTypeInfo

public org.w3c.dom.TypeInfo getSchemaTypeInfo()

The type information associated with this attribute. While the type information contained in this attribute is guarantee to be correct after loading the document or invoking Document.normalizeDocument(), schemaTypeInfo may not be reliable if the node was moved.

Specified by:

getSchemaTypeInfo in interface org.w3c.dom.Attr

Overrides:

getSchemaTypeInfo in class AbstractNode

Since:

DOM Level 3

isId

public boolean isId()

Returns whether this attribute is known to be of type ID (i.e. to contain an identifier for its owner element) or not. When it is and its value is unique, the ownerElement of this attribute can be retrieved using the method Document.getElementById . The implementation could use several ways to determine if an attribute node is known to contain an identifier:

• If validation occurred using an XML Schema [XML Schema Part 1] while loading the document or while invoking Document.normalizeDocument(), the post-schema-validation infoset contributions (PSVI contributions) values are used to determine if this attribute is a schema-determined ID attribute using the schema-determined ID definition in [XPointer] .
• If validation occurred using a DTD while loading the document or while invoking Document.normalizeDocument(), the infoset [type definition] value is used to determine if this attribute is a DTD-determined ID attribute using the DTD-determined ID definition in [XPointer] .
• from the use of the methods Element.setIdAttribute(), Element.setIdAttributeNS(), or Element.setIdAttributeNode(), i.e. it is an user-determined ID attribute;

  Note: XPointer framework (see section 3.2 in [XPointer] ) consider the DOM user-determined ID attribute as being part of the XPointer externally-determined ID definition.

• using mechanisms that are outside the scope of this specification, it is then an externally-determined ID attribute. This includes using schema languages different from XML schema and DTD.

If validation occurred while invoking Document.normalizeDocument(), all user-determined ID attributes are reset and all attribute nodes ID information are then reevaluated in accordance to the schema used. As a consequence, if the Attr.schemaTypeInfo attribute contains an ID type, isId will always return true.

Specified by:

isId in interface org.w3c.dom.Attr

Overrides:

isId in class AbstractNode
