Method Detail

getReport

protected List<T> getReport(Object[] _params,
                            PageInfo pageInfo,
                            org.apache.commons.collections.Transformer dataGenerator)

getCount

protected long getCount(Object[] _params,
                        org.apache.commons.collections.Transformer countQuery)

getReport

public List<T> getReport(Object[] _params,
                         PageInfo pageInfo)

Parameters:

_params - as Object[] @nullable true; params maybe even supplied by the context (check implementation)

pageInfo - as PageInfo @nullable true

Returns:

List of T

getCount

public long getCount(Object[] _params)

Parameters:

_params - as Object[] @nullable true; params maybe even supplied by the context (check implementation)

Returns:

count as long

getDataGenerator

public org.apache.commons.collections.Transformer getDataGenerator()

Generate the Source tuples from the Data Source; the Transformer should return a List of objects (see JPAQueryTransformer)

Can be null:

false

setDataGenerator

public void setDataGenerator(org.apache.commons.collections.Transformer dataGenerator)

Generate the Source tuples from the Data Source; the Transformer should return a List of objects (see JPAQueryTransformer)

Can be null:

false

getCountQuery

public org.apache.commons.collections.Transformer getCountQuery()

Run a count query for the dataGenerator

Can be null:

true; will use the dataGenerator to count if null

setCountQuery

public void setCountQuery(org.apache.commons.collections.Transformer countQuery)

Run a count query for the dataGenerator

Can be null:

true; will use the dataGenerator to count if null

getNoParamsDataGenerator

public org.apache.commons.collections.Transformer getNoParamsDataGenerator()

An optional no param based data generator. This is used to produce a default report; for reports that requires filters but on first load still want to show results.

setNoParamsDataGenerator

public void setNoParamsDataGenerator(org.apache.commons.collections.Transformer noParamsDataGenerator)

An optional no param based data generator. This is used to produce a default report; for reports that requires filters but on first load still want to show results.

getNoParamsCountQuery

public org.apache.commons.collections.Transformer getNoParamsCountQuery()

A countQuery for noParamsDataGenerator

setNoParamsCountQuery

public void setNoParamsCountQuery(org.apache.commons.collections.Transformer noParamsCountQuery)

A countQuery for noParamsDataGenerator

getReporterMeta

public ReporterMeta getReporterMeta()

Reference to ReporterMeta
Can be used to refer to original details about various columns in the Report.

Returns:

ReporterMeta

Can be null:

true

setReporterMeta

public void setReporterMeta(ReporterMeta reporterMeta)

Reference to ReporterMeta
Can be used to refer to original details about various columns in the Report.

Can be null:

true
