Class TagInfo

public TagInfo(java.lang.String tagName,
               java.lang.String tagClassName,
               java.lang.String bodycontent,
               java.lang.String infoString,
               TagLibraryInfo taglib,
               TagExtraInfo tagExtraInfo,
               TagAttributeInfo attributeInfo)

Constructor for TagInfo from data in the JSP 1.1 format for TLD. This class is to be instantiated only from the TagLibrary code under request from some JSP code that is parsing a TLD (Tag Library Descriptor). Note that, since TagLibibraryInfo reflects both TLD information and taglib directive information, a TagInfo instance is dependent on a taglib directive. This is probably a design error, which may be fixed in the future.

Parameters:

tagName - The name of this tag

tagClassName - The name of the tag handler class

bodycontent - Information on the body content of these tags

infoString - The (optional) string information for this tag

taglib - The instance of the tag library that contains us.

tagExtraInfo - The instance providing extra Tag info. May be null

attributeInfo - An array of AttributeInfo data from descriptor. May be null;

Constructor for TagInfo from data in the JSP 1.2 format for TLD. This class is to be instantiated only from the TagLibrary code under request from some JSP code that is parsing a TLD (Tag Library Descriptor). Note that, since TagLibibraryInfo reflects both TLD information and taglib directive information, a TagInfo instance is dependent on a taglib directive.

Parameters:

tagName - The name of this tag

tagClassName - The name of the tag handler class

bodycontent - Information on the body content of these tags

infoString - The (optional) string information for this tag

taglib - The instance of the tag library that contains us.

tagExtraInfo - The instance providing extra Tag info. May be null

attributeInfo - An array of AttributeInfo data from descriptor. May be null;

displayName - A short name to be displayed by tools

smallIcon - Path to a small icon to be displayed by tools

largeIcon - Path to a large icon to be displayed by tools

public TagAttributeInfo[] getAttributes()

Attribute information (in the TLD) on this tag. The return is an array describing the attributes of this tag, as indicated in the TLD. A null return means no attributes.

Returns:

The array of TagAttributeInfo for this tag.

public TagExtraInfo getTagExtraInfo()

The instance (if any) for extra tag information

Returns:

The TagExtraInfo instance, if any.

public TagLibraryInfo getTagLibrary()

The instance of TabLibraryInfo we belong to.

Returns:

the tab library instance we belong to.

public TagVariableInfo[] getTagVariableInfos()

Get TagVariableInfo objects associated with this TagInfo

Returns:

A TagVariableInfo object associated with this

public VariableInfo[] getVariableInfo(TagData data)

Information on the scripting objects created by this tag at runtime. This is a convenience method on the associated TagExtraInfo class.

Default is null if the tag has no "id" attribute, otherwise, {"id", Object}

Parameters:

data - TagData describing this action.

Returns:

Array of VariableInfo elements.

public boolean isValid(TagData data)

Translation-time validation of the attributes. This is a convenience method on the associated TagExtraInfo class.

Parameters:

data - The translation-time TagData instance.

Returns:

Whether the data is valid.

public void setTagExtraInfo(TagExtraInfo tei)

Set the instance for extra tag information

Parameters:

tei - the TagExtraInfo instance

public void setTagLibrary(TagLibraryInfo tl)

Set the TagLibraryInfo property. Note that a TagLibraryInfo element is dependent not just on the TLD information but also on the specific taglib instance used. This means that a fair amount of work needs to be done to construct and initialize TagLib objects. If used carefully, this setter can be used to avoid having to create new TagInfo elements for each taglib directive.

Parameters:

tl - the TagLibraryInfo to assign
