Method Detail

isKeepPrecedingWhiteSpace

public boolean isKeepPrecedingWhiteSpace()

Description copied from class: GroovySyntaxTag

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.

Specified by:

isKeepPrecedingWhiteSpace in class GroovySyntaxTag

Returns:

true if any whitespace immediately before the tag should be kept in the output - false if it is to be discarded

isAllowPrecedingContent

public boolean isAllowPrecedingContent()

Description copied from class: GroovySyntaxTag

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.

TODO rework this and combine with isKeepPrecedingWhiteSpace as really they are used in the same situations

Specified by:

isAllowPrecedingContent in class GroovySyntaxTag

Returns:

true if any content is allowed immediately before the tag - false if it is an error to have such content before it

doStartTag

public void doStartTag()

Description copied from interface: GrailsTag

Process the start tag

doEndTag

public void doEndTag()

Description copied from interface: GrailsTag

process the end tag

getName

public java.lang.String getName()
