Class Element
- DTDConstants, Serializable
Stores the element information, obtained by parsing SGML DTD
tag
<!ELEMENT .. >. This class has no public
constructor and can only be instantiated using the
DTD methods
SGML defines elements that represent structures or
behavior. An element typically consists of a start tag, content, and an
end tag. Hence the elements are not tags. The HTML 4.0 definition specifies
that some elements are not required to have the end tags. Also, some
HTML elements (like
<hr>) have no content. Element names
are case sensitive.

content
public ContentModel content
The content model, defining elements, entities and DTD text
that may/may not occur inside this element.
data
public Object data
A field to store additional user data for this Element.
exclusions
public BitSet exclusions
Contains refernces to elements that must NOT occur inside this element,
at any level of hierarchy.
inclusions
public BitSet inclusions
Contains refernces to elements that must CAN occur inside this element,
at any level of hierarchy.
index
public int index
This field contains the unique integer identifier of this Element,
used to refer the element (more exactly, the element flag)
in inclusions and exclusions bit set.
oEnd
public boolean oEnd
True is this element need not to have the closing tag, false
otherwise. The HTML 4.0 definition specifies
that some elements (like <hr>are
not required to have the end tags.
oStart
public boolean oStart
True is this element need not to have the starting tag, false
otherwise. The HTML 4.0 definition specifies
that some elements (like <head> or
<body>) are
not required to have the start tags.
type
public int type
The element type, containing value, defined in DTDConstants.
In this implementation, the element type can be
CDATA, RCDATA, EMPTY or ANY.
getAttribute
public AttributeList getAttribute(String attribute)
Get the element attribute by name.
attribute - the attribute name, case insensitive.
- the correspoding attribute of this element. The class,
for storing as attribute list, as a single attribute, is used to
store a single attribute in this case.
getAttributeByValue
public AttributeList getAttributeByValue(String a_value)
Get the element attribute by its value.
a_value - the attribute value, case insensitive.
- the correspoding attribute of this element. The class,
for storing as attribute list, as a single attribute, is used to
store a single attribute in this case. If there are several
attributes with the same value, there is no garranty, which one
is returned.
getContent
public ContentModel getContent()
Get the content model, defining elements, entities and DTD text
that may/may not occur inside this element.
getIndex
public int getIndex()
Get the unique integer identifier of this Element,
used to refer the element (more exactly, the element flag)
in inclusions and exclusions bit set.
WARNING: This value may not be the same between different
implementations.
getType
public int getType()
Get the element type.
- one of the values, defined DTDConstants.
In this implementation, the element type can be
CDATA, RCDATA, EMPTY or ANY.
isEmpty
public boolean isEmpty()
Returns true for the element with no content.
Empty elements are defined with the SGML DTD keyword "EMPTY".
- true if content model field (content) method is equal to
null or its method empty() returns true.
name2type
public static int name2type(String a_type)
Converts the string representation of the element type
into its unique integer identifier, defined in DTDConstants.
a_type - A name of the type
- DTDConstants.CDATA, DTDConstants.RCDATA, DTDConstants.EMPTY,
DTDConstants.ANY or null if the type name is not
"CDATA", "RCDATA", "EMPTY" or "ANY". This function is case sensitive.
omitEnd
public boolean omitEnd()
True is this element need not to have the starting tag, false
otherwise.s element need not to have the closing tag, false
otherwise. The HTML 4.0 definition specifies
that some elements (like <hr>are
not required to have the end tags.
omitStart
public boolean omitStart()
True is this element need not to have the closing tag, false
otherwise. The HTML 4.0 definition specifies
that some elements (like <head> or
<body>) are
not required to have the start tags.
