Class TinyAttributeImpl

  • All Implemented Interfaces:
    javax.xml.transform.Source, javax.xml.transform.SourceLocator, GroundedValue, Item, NodeInfo, Sequence, Location, org.xml.sax.Locator
    public final class TinyAttributeImpl
extends TinyNodeImpl
    A node in the XML parse tree representing an attribute. Note that this is generated only "on demand", when the attribute is selected by a select pattern.

    • Method Detail

      • setSystemId

        public void setSystemId​(java.lang.String uri)
        Description copied from class: TinyNodeImpl
        Set the system id of this node.

        This method is present to ensure that the class implements the javax.xml.transform.Source interface, so a node can be used as the source of a transformation.

        Specified by:
        setSystemId in interface javax.xml.transform.Source
        Overrides:
        setSystemId in class TinyNodeImpl

      • getSystemId

        public java.lang.String getSystemId()
        Description copied from class: TinyNodeImpl
        Get the system ID for the entity containing the node.
        Specified by:
        getSystemId in interface Location
        Specified by:
        getSystemId in interface org.xml.sax.Locator
        Specified by:
        getSystemId in interface NodeInfo
        Specified by:
        getSystemId in interface javax.xml.transform.Source
        Specified by:
        getSystemId in interface javax.xml.transform.SourceLocator
        Overrides:
        getSystemId in class TinyNodeImpl
        Returns:
        the System Identifier of the entity in the source document containing the node, or null if not known or not applicable.

      • getRoot

        public NodeInfo getRoot()
        Get the root node of the tree (not necessarily a document node)
        Specified by:
        getRoot in interface NodeInfo
        Overrides:
        getRoot in class TinyNodeImpl
        Returns:
        the NodeInfo representing the root of this tree

      • getSequenceNumber

        protected long getSequenceNumber()
        Get the node sequence number (in document order). Sequence numbers are monotonic but not consecutive. In this implementation, elements have a zero least-significant word, while attributes and namespaces use the same value in the top word as the containing element, and use the bottom word to hold a sequence number, which numbers namespaces first and then attributes.
        Overrides:
        getSequenceNumber in class TinyNodeImpl
        Returns:
        the sequence number

      • getNodeKind

        public final int getNodeKind()
        Return the type of node.
        Returns:
        Node.ATTRIBUTE
        See Also:
        Type

      • getStringValue

        public java.lang.String getStringValue()
        Return the string value of the node.
        Returns:
        the attribute value
        See Also:
        Item.getStringValueCS()

      • 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
        Returns:
        an integer fingerprint; two nodes with the same fingerprint have the same expanded QName. For unnamed nodes (text nodes, comments, document nodes, and namespace nodes for the default namespace), returns -1.

      • 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
        Overrides:
        getPrefix in class TinyNodeImpl
        Returns:
        the prefix part of the name. For an unnamed node, return null.

      • getDisplayName

        Overrides:
        getDisplayName in class TinyNodeImpl
        Returns:

      • getLocalPart

        public java.lang.String getLocalPart()
        Get the local name of this node.
        Specified by:
        getLocalPart in interface NodeInfo
        Overrides:
        getLocalPart 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:

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

      • getSchemaType

        public SchemaType getSchemaType()
        Get the type annotation of this node, if any. The type annotation is represented as SchemaType object.

        Types derived from a DTD are not reflected in the result of this method.

        Specified by:
        getSchemaType in interface NodeInfo
        Overrides:
        getSchemaType in class TinyNodeImpl
        Returns:
        For element and attribute nodes: the type annotation derived from schema validation (defaulting to xs:untyped and xs:untypedAtomic in the absence of schema validation). For comments, text nodes, processing instructions, and namespaces: null. For document nodes, either xs:untyped if the document has not been validated, or xs:anyType if it has.
        Since:
        9.4

      • atomize

        public AtomicSequence atomize()
                       throws XPathException
        Get the typed value.
        Returns:
        the typed value. This will either be a single AtomicValue or a Value whose items are atomic values.
        Throws:
        XPathException - if the node has no typed value, for example if it is an element node with element-only content
        Since:
        8.5

      • hashCode

        public int hashCode()
        The hashCode() method obeys the contract for hashCode(): that is, if two objects are equal (represent the same node) then they must have the same hashCode()
        Specified by:
        hashCode in interface NodeInfo
        Overrides:
        hashCode in class TinyNodeImpl
        Since:
        8.7 Previously, the effect of the equals() and hashCode() methods was not defined. Callers should therefore be aware that third party implementations of the NodeInfo interface may not implement the correct semantics.
