Class OutSupport

java.lang.Object

jakarta.servlet.jsp.tagext.TagSupport

jakarta.servlet.jsp.tagext.BodyTagSupport

org.apache.taglibs.standard.tag.common.core.OutSupport

All Implemented Interfaces:

jakarta.servlet.jsp.tagext.BodyTag, jakarta.servlet.jsp.tagext.IterationTag, jakarta.servlet.jsp.tagext.JspTag, jakarta.servlet.jsp.tagext.Tag, java.io.Serializable

Direct Known Subclasses:

OutTag, OutTag

public class OutSupport
extends jakarta.servlet.jsp.tagext.BodyTagSupport

Support for handlers of the <out> tag, which simply evalutes and prints the result of the expression it's passed. If the result is null, we print the value of the 'default' attribute's expression or our body (which two are mutually exclusive, although this constraint is enforced outside this handler, in our TagLibraryValidator).
