Constructor Detail

AttrImpl

public AttrImpl()

Default Constructor

AttrImpl

public AttrImpl(org.w3c.dom.Element element,
                java.lang.String prefix,
                java.lang.String localpart,
                java.lang.String rawname,
                java.lang.String uri,
                java.lang.String value)

Constructs an attribute.

Parameters:

element - Element which owns this attribute

prefix - The QName prefix.

localpart - The QName localpart.

rawname - The QName rawname.

uri - The uri binding for the associated prefix.

value - The value of the attribute.

Method Detail

getName

public java.lang.String getName()

Description copied from interface: org.w3c.dom.Attr

Returns the name of this attribute.

Specified by:

getName in interface org.w3c.dom.Attr

getSpecified

public boolean getSpecified()

Description copied from interface: org.w3c.dom.Attr

If this attribute was explicitly given a value in the original document, this is true; otherwise, it is false. Note that the implementation is in charge of this attribute, not the user. If the user changes the value of the attribute (even if it ends up having the same value as the default value) then the specified flag is automatically flipped to true. To re-specify the attribute as the default value from the DTD, the user must delete the attribute. The implementation will then make a new attribute available with specified set to false and the default value (if one exists).
In summary: If the attribute has an assigned value in the document then specified is true, and the value is the assigned value.If the attribute has no assigned value in the document and has a default value in the DTD, then specified is false, and the value is the default value in the DTD.If the attribute has no assigned value in the document and has a value of #IMPLIED in the DTD, then the attribute does not appear in the structure model of the document.If the ownerElement attribute is null (i.e. because it was just created or was set to null by the various removal and cloning operations) specified is true.

Specified by:

getSpecified in interface org.w3c.dom.Attr

getValue

public java.lang.String getValue()

Description copied from interface: org.w3c.dom.Attr

On retrieval, the value of the attribute is returned as a string. Character and general entity references are replaced with their values. See also the method getAttribute on the Element interface.
On setting, this creates a Text node with the unparsed contents of the string. I.e. any characters that an XML processor would recognize as markup are instead treated as literal text. See also the method setAttribute on the Element interface.

Specified by:

getValue in interface org.w3c.dom.Attr

getOwnerElement

public org.w3c.dom.Element getOwnerElement()

Description copied from interface: org.w3c.dom.Attr

The Element node this attribute is attached to or null if this attribute is not in use.

Specified by:

getOwnerElement in interface org.w3c.dom.Attr

setValue

public void setValue(java.lang.String value)
              throws org.w3c.dom.DOMException

Description copied from interface: org.w3c.dom.Attr

On retrieval, the value of the attribute is returned as a string. Character and general entity references are replaced with their values. See also the method getAttribute on the Element interface.
On setting, this creates a Text node with the unparsed contents of the string. I.e. any characters that an XML processor would recognize as markup are instead treated as literal text. See also the method setAttribute on the Element interface.

Specified by:

setValue in interface org.w3c.dom.Attr

Throws:

org.w3c.dom.DOMException - NO_MODIFICATION_ALLOWED_ERR: Raised when the node is readonly.

isId

public boolean isId()

Since:

DOM Level 3

getSchemaTypeInfo

public org.apache.xerces.dom3.TypeInfo getSchemaTypeInfo()

Method getSchemaTypeInfo.

Returns:

TypeInfo
