CharSequence attribute)

Method Details

get

public static HTMLLinkContext get(CharSequence el,
CharSequence attr)

return an instance of HTMLLinkContext for attribute attr in element el. returns pre-allocated shared instance for common case, or new instance for others.

Parameters:

el - element name

attr - attribute name

Returns:

instance of HTMLLinkContext

get

public static HTMLLinkContext get(String path)

return an instance of HTMLLinkContext for path path. returns pre-allocated shared instance for common case, or new instance for others.

TODO: most code calling this method builds path by concatenating element name and attribute name. consider changing such code to call get(CharSequence, CharSequence) instead.

Parameters:

path - element and attribute in XLink-like path notation

Returns:

instance of HTMLLinkContext

toString

public String toString()

Overrides:

toString in class Object
