public int getLength()

Gets the length of the tag in characters.

Returns:

The tag's length

getLineNumber

public int getLineNumber()

Get the line number.

Returns:

Returns the lineNumber.

getName

public java.lang.String getName()

Gets the name of the tag, for example the tag 's name would be 'b'.

Returns:

The tag's name

getNameChanged

public boolean getNameChanged()

Get whether the name of this component tag was changed.

Returns:

Returns true if the name of this component tag was changed

getNamespace

public java.lang.String getNamespace()

Namespace of the tag, if available. For example, <wicket:link>.

Returns:

The tag's namespace

getOpenTag

public final XmlTag getOpenTag()

Assuming this is a close tag, return the corresponding open tag

Returns:

The open tag. Null, if no open tag available

getPos

public int getPos()

Gets the location of the tag in the input string.

Returns:

Tag location (index in input string)

getString

public java.lang.String getString(java.lang.String key)

Get a string attribute.

Parameters:

key - The key

Returns:

The string value

getType

public XmlTag.Type getType()

Get the tag type.

Returns:

the tag type (OPEN, CLOSE or OPEN_CLOSE).

isClose

public boolean isClose()

Gets whether this is a close tag.

Returns:

True if this tag is a close tag

isMutable

public final boolean isMutable()

Returns:

True, if tag is mutable

isOpen

public boolean isOpen()

makeImmutable

public void makeImmutable()

Makes this tag object immutable by making the attribute map unmodifiable. Immutable tags cannot be made mutable again. They can only be copied into new mutable tag objects.

Puts a boolean attribute.

Parameters:

key - The key

value - The value

Returns:

previous value associated with specified key, or null if there was no mapping for key. A null return can also indicate that the map previously associated null with the specified key, if the implementation supports null values.

Puts a string attribute.

Parameters:

key - The key

value - The value
