Field Summary

(package private) String	name If we are in a value tag, the name of the queryProjection that computes the title field, otherwise null
(package private) int	nameIndex If we are in a value tag, the index of the queryProjection that computes the title field, otherwise null

expr, parentKey, projectionIndex, type

Constructor Summary

SetValueComputer(AnalysableTag analyzed, MultipleKey parentListKey, FieldDefinition set, String setExpr, PageCache pageCache)
Makes a query that has an extra FROM: the set requested.

Method Summary

void	doEndAnalyze(PageCache pageCache) Computes nameIndex
Object	getValue(PageContext pageContext) Goes through the iterationGroupData and returns a vector with the set values.
void	print(ValueTag running, PageCache pageCache) Goes through the iterationGroupData and prints the set values, comma-separated; also sets var (Vector with the set values) and printVar

Constructor Detail

SetValueComputer

SetValueComputer(AnalysableTag analyzed,
                 MultipleKey parentListKey,
                 FieldDefinition set,
                 String setExpr,
                 PageCache pageCache)

Makes a query that has an extra FROM: the set requested. As projections, add the key of the set type and, if we are in a value tag, the title field.

Parameters:

analyzed - the tag that is analyzed

parentListKey - the key of the parent list

set - the FieldDefinition of the set we want to compute a value of

setExpr - the expression of the set

pageCache - the page cache of the current page

Method Detail

doEndAnalyze

public void doEndAnalyze(PageCache pageCache)

Computes nameIndex

Overrides:

doEndAnalyze in class QueryValueComputer

Parameters:

pageCache - the page cache of the current page

getValue

public Object getValue(PageContext pageContext)
                throws LogicException

Goes through the iterationGroupData and returns a vector with the set values. Used only by InputTag

Overrides:

getValue in class ValueComputer

Parameters:

running - the tag that is currently running

Returns:

the computed value

Throws:

LogicException

print

public void print(ValueTag running,
                  PageCache pageCache)
           throws JspException,
                  LogicException

Goes through the iterationGroupData and prints the set values, comma-separated; also sets var (Vector with the set values) and printVar

Overrides:

print in class ValueComputer

Parameters:

running - the tag that is currently running

pageCache - the pageCache of the current page

Throws:

JspException

LogicException
