java.lang.Objectorg.codehaus.groovy.grails.web.taglib.GroovySyntaxTag
public abstract class GroovySyntaxTag
A tag type that gets translated directly into Groovy syntax by the GSP parser.
This is used for Java-implemented internal tags that the Parse class uses to directly inject code into the generated GSP source. These tags can do more than custom taglibs as the operate at the code level, rather than at the runtime view rendering level

Tags must return the correct value to indicate whether or not whitespace before this tag should be kept in the output.
This is for tags that must follow other tags, such as g:else or g:elseif that do not allow content between them and the previous tag, and need to swallow the whitespace between them.
public abstract boolean isAllowPrecedingContent()
Tags must return the correct value to indicate whether or not non-whitespace content is permitted before this tag.
This is for tags that must follow other tags, such as g:else or g:elseif that do not allow content between them and the previous tag. It is simply used as a safety mechanism to trap incorrect usage of tags.
