All Implemented Interfaces:

Iterable<Range>

public abstract class Match
extends Object
implements Iterable<Range>

The Match class uniquely identifies a particular element within a body of XHTML markup, and provides methods for performing every type of operation possible on any element. (Note that not all operations make sense for all elements.) It is created to represent an element selected by a CSS2 pattern applied to a body of markup by the CSSPatterns class, which returns the zero, or more, matches produced by its search in a Results object.

The Match class is abstract. Separate implementations handle the simple case of elements in immutable markup (ImmutableMatch) where none of the modification functions do anything but throw exceptions, and the complex case of elements in mutable markup (MutableMatch) where the modification functions actually work.

Method Detail

create

public static Match create(Markup Markup,
                           Range Item,
                           int Index)

Creates the type of Match object (ImmutableMatch} or {MutableMatch) appropriate to the type of Markup object (ImmutableMarkup or MutableMarkup) in which the specified element occurs.

Parameters:

Markup - The Markup object in which the specified element is stored.

Item - The markup element to be represented by this class.

Index - The index of the markup element within the Markup object.

Returns:

A Match subclass uniquely identifying the specified markup element.

getMarkup

public abstract Markup getMarkup()

Returns the Markup object in which this match occurs. This will always be the same Markup object that was passed to the constructor.

Returns:

The Markup object in which this Match occurs.

getIndex

public abstract int getIndex()
                      throws NoSuchElementException

The index of this element in the markup that contains it. When the containing markup is immutable, this index is a constant, but when the markup is mutable, the index can change. In the latter case, this method verifies the index of the element, and corrects it if there's been a change.

Returns:

The index of this element within the markup.

Throws:

NoSuchElementException - If this element is no longer present in the markup.

get

public abstract Range get()
                   throws NoSuchElementException

Returns the markup element represented by this Match object.

Returns:

The markup element represented by this Match object.

Throws:

NoSuchElementException - If this element is no longer present in the markup.

toResults

public Results toResults()

Returns a Form object for examining and/or manipulating the XHTML "form" element (and the controls within it) that is referenced by the first match in this Results object. If you intend to modify the "form" element, or its contents, you should already be operating on MutableMarkup before invoking toForm. A mutable version of ImmutableMarkup is created trivially by merely invoking the Markup.getMutable() method.

Returns:

A Form object for manipulating the "form" element referenced by the first match in this Results object.

Throws:

FormNotFoundException - If the this Match instances does not refer to a "form" element.

See Also:

Adds one or more class names to the "class" attribute of this markup element. If this markup element has no "class" attribute, one is created. Redundant additions of class names are detected and omitted, so duplicates will not be created. Calling addAttribute and supplying "class" as the attribute name has exactly the same effect as this method, but is less efficient.

Parameters:

ClassList - A space-separated list of class names.

Returns:

A Match object identifying this markup element. If this element was immutable, a mutable version of it will have been created, substitued into this markup (assuming the markup itself is mutable), and the Match returned will refer to the new mutable form of this element.

Throws:

TagException - If a problem is encountered with the manipulation of the markup.

setClass

public Match setClass(String ClassList)
               throws TagException

Replaces any existing value of the "class" attribute of this markup element with the supplied space-separated list of class names. Redundant additions of class names are detected and omitted, so duplicates will not be created. Calling setAttribute and supplying "class" as the attribute name has exactly the same effect as this method, but is less efficient.

Parameters:

ClassList - A space-separated list of class names.

Returns:

A Match object identifying this markup element. If this element was immutable, a mutable version of it will have been created, substitued into this markup (assuming the markup itself is mutable), and the Match returned will refer to the new mutable form of this element.

Throws:

TagException - If a problem is encountered with the manipulation of the markup.

deleteClass

public Match deleteClass(String ClassList)
                  throws TagException

Deletes the supplied space-separated list of class names from the value of this markup element's "class" attribute. Deleting class names that aren't actually present in the value of this markup element's "class" attribute is no problem. If you want to remove all class names from this element, use deleteAttribute and pass "class" as the attribute name.

Parameters:

ClassList - A space-separated list of class names.

Returns:

A Match object identifying this markup element. If this element was immutable, a mutable version of it will have been created, substitued into this markup (assuming the markup itself is mutable), and the Match returned will refer to the new mutable form of this element.

Throws:

TagException - If a problem is encountered with the manipulation of the markup.

hasAttributeOfValue

public boolean hasAttributeOfValue(String AttrName,
                                   String AttrValue)

Returns true if this markup element has an attribute of the specified name and value.

Parameters:

AttrName - Name of the attribute.

AttrValue - Value of the attribute.

Returns:

true if the attribute is present and is of the specified value, false otherwise.

hasAttribute

public boolean hasAttribute(String AttrName)

Returns true if this markup element includes the specified attribute.

Parameters:

AttrName - Name of the attribute.

Returns:

true if the attribute is present, false otherwise.

hasNonEmptyAttribute

public boolean hasNonEmptyAttribute(String AttrName)

Returns true if this markup element includes the specified attribute, and the value of the attribute is of a non-zero length. Otherwise, this method returns false.

Parameters:

AttrName - Name of the attribute.

Returns:

true if this markup element includes the specified attribute, and the value of the attribute is of a non-zero length, false otherwise.

getAttribute

public String getAttribute(String AttrName)

Returns the value of the named attribute, or null if there is no such attribute in this markup element.

Parameters:

AttrName - Name of the attribute.

Returns:

Value of the attribute, or null if no such attribute.

addAttribute

public Match addAttribute(String AttrName,
                          Object AttrValue)
                   throws TagException

Adds an attribute to any markup element that is allowed to have attributes. If the markup element already has an attribute of the specified name, the new value is appended to the existing value. Note that nothing clever is done when appending, such as placing spaces between the original value and the new material that is appended to it. Instead, this is a plain and simple append operation. Because of that, it is possible to use this method to, for instance, progressively build-up a URL in an "a" (anchor) element's "href" attribute. When appending is not desired, use the setAttribute method instead.

If the attribute name is "class", this method performs the same function as the addClass method, but somewhat less efficiently.

Parameters:

AttrName - Name of the attribute.

AttrValue - Value of a new attribute, or the string to be appended to the value of an existing attribute.

Returns:

A Match object identifying this markup element. If this element was immutable, a mutable version of it will have been created, substitued into this markup (assuming the markup itself is mutable), and the Match returned will refer to the new mutable form of this element.

Throws:

TagException - If a problem is encountered with the manipulation of the markup.

setAttribute

public Match setAttribute(String AttrName,
                          Object AttrValue)
                   throws TagException

Replaces the value of an existing attribute, or creates a new attribute, in any markup element that is allowed to have attributes. If the attribute name is "class", this method performs the same function as the setClass method, but somewhat less efficiently.

Parameters:

AttrName - Name of the attribute.

AttrValue - Value of the attribute.

Returns:

A Match object identifying this markup element. If this element was immutable, a mutable version of it will have been created, substitued into this markup (assuming the markup itself is mutable), and the Match returned will refer to the new mutable form of this element.

Throws:

TagException - If a problem is encountered with the manipulation of the markup.

updateAttribute

public Match updateAttribute(String AttrName,
                             Object AttrValue)
                      throws TagException

Replaces the value of an existing attribute, but never creates a new attribute, in any markup element that is allowed to have attributes. If the attribute name is "class", this method performs the same function as the setClass method, but somewhat less efficiently.

Parameters:

AttrName - Name of the attribute.

AttrValue - Value of the attribute.

Returns:

A Match object identifying this markup element. If this element was immutable, a mutable version of it will have been created, substitued into this markup (assuming the markup itself is mutable), and the Match returned will refer to the new mutable form of this element.

Throws:

TagException - If a problem is encountered with the manipulation of the markup.

deleteAttribute

public Match deleteAttribute(String AttrName)
                      throws TagException

Removes an attribute from this markup element.

Parameters:

AttrName - Name of the attribute.

Throws:

TagException - If a problem is encountered with the manipulation of the markup.

iterator

public Iterator<Range> iterator()

iterator in interface Iterable<Range>

Returns:

An Iterator of this element and any children it may possess.

enumerate

public MarkupEnumeration enumerate()
