Constructor Details

TagLibraryInfoImpl

public TagLibraryInfoImpl(String prefix,
 String uri,
 TagLibraryInfoImpl delegate,
 PageInfo pageInfo)

Constructor which populates a TagLibraryInfoImpl from a given TagLibraryInfoImpl, and associates the new TagLibraryInfoImpl with the given translation unit (pageInfo).

Parameters:

prefix - The taglib's namespace prefix

uri - The taglib's uri

delegate - The taglib from which the new TagLibraryInfoImpl is populated

pageInfo - The translation unit with which the new TagLibraryInfoImpl is to be associated

 ParserController pc,
 String prefix,
 String uriIn,
 String[] location,
 ErrorDispatcher err)
                   throws JasperException

Constructor which builds a TagLibraryInfoImpl by parsing a TLD.

Throws:

 PrintWriter w)

toString

public String toString()

Overrides:

toString in class Object

getResourceAsStream

Throws:

JasperException

getTagLibraryInfos

public TagLibraryInfo[] getTagLibraryInfos()

Returns an array of TagLibraryInfo objects representing the entire set of tag libraries (including this TagLibraryInfo) imported by taglib directives in the translation unit that references this TagLibraryInfo.
