setBodyContent

public void setBodyContent(BodyContent bc)

Specified by:

setBodyContent in interface BodyTag

doInitBody

public void doInitBody()

Specified by:

doInitBody in interface BodyTag

setTagKey

public void setTagKey(PageCache pageCache)

Sets tagKey to uniquely identify this tag. Called at analysis time before doStartAnalyze() and at runtime before doMakumbaStartTag()

Overrides:

setTagKey in class AnalysableTag

Parameters:

pageCache - the page cache of the current page

See Also:

AnalysableTag.doAnalyzedStartTag(org.makumba.analyser.PageCache), AnalysableTag.doStartAnalyze(org.makumba.analyser.PageCache)

doStartAnalyze

public void doStartAnalyze(PageCache pageCache)

Determines the ValueComputer and associates it with the tagKey . If we use Hibernate we need to adjust the syntax

Overrides:

doStartAnalyze in class AnalysableTag

Parameters:

pageCache - the page cache of the current page FIXME QueryExecutionProvider should tell us the syntax for the if boolean test

doEndAnalyze

public void doEndAnalyze(PageCache pageCache)

Tells the ValueComputer to finish analysis, check for proper test result type

Overrides:

doEndAnalyze in class AnalysableTag

Parameters:

pageCache - the page cache of the current page

doAnalyzedStartTag

public int doAnalyzedStartTag(PageCache pageCache)
                       throws JspException,
                              LogicException

Asks the ValueComputer to calculate the expression, and SKIP_BODY if false.

Overrides:

doAnalyzedStartTag in class AnalysableTag

Parameters:

pageCache - the page cache of the current page

Throws:

JspException

LogicException
