PARAMETER_DOCUMENT_BUILDER_FACTORY

public static final String PARAMETER_DOCUMENT_BUILDER_FACTORY

Built-in parameter holdin the value of the javax.xml.parsers.DocumentBuilderFactor used to create documents of type org.w3c.dom.Document

Constant Field Values

PARAMETER_XML_NAMESPACE_MAP

public static final String PARAMETER_XML_NAMESPACE_MAP

Parameter that holds the java.util.Map<String,String> with XML namespace information in the <prefix, uri> format

See Also:

Constant Field Values

XML_NAMESPACE_PREFIX

public static final String XML_NAMESPACE_PREFIX

Prefix for properties holding the namespace prefix and uri: e.g. net.sf.jasperreports.xml.namespace.{prefix} = uri

This property has a lower priority than PARAMETER_XML_NAMESPACE_MAP, which if it is specified it will cause the prefixed properties not to be searched for.

See Also:

Constant Field Values

XML_DETECT_NAMESPACES

public static final String XML_DETECT_NAMESPACES

Boolean parameter/property that specifies whether the XML document should be parsed for namespaces or not.

This parameter is meaningful only when:

• the PARAMETER_XML_NAMESPACE_MAP parameter is not provided or provided with a null value
• there are no properties prefixed with XML_NAMESPACE_PREFIX;
• the xpath query expression that is provided contains XML namespace prefixes

It defaults to false

Method Detail

getBuiltinParameters

public Object[] getBuiltinParameters()

Description copied from interface: QueryExecuterFactory

Returns the built-in parameters associated with this query type.

These parameters will be created as system-defined parameters for each report/dataset having a query of this type.

The returned array should contain consecutive pairs of parameter names and parameter classes (e.g. {"Param1", String.class, "Param2", "List.class"}).

Specified by:

getBuiltinParameters in interface JRQueryExecuterFactory

Specified by:

getBuiltinParameters in interface QueryExecuterFactory

Overrides:

getBuiltinParameters in class JRXPathQueryExecuterFactory

Returns:

array of built-in parameter names and types associated with this query type

createQueryExecuter

public JRQueryExecuter createQueryExecuter(JasperReportsContext jasperReportsContext,
                                  JRDataset dataset,
                                  Map<String,? extends JRValueParameter> parameters)
                                    throws JRException

Description copied from interface: QueryExecuterFactory

Creates a query executer.

This method is called at fill time for reports/datasets having a query supported by this factory.

Specified by:

createQueryExecuter in interface QueryExecuterFactory

Overrides:

createQueryExecuter in class JRXPathQueryExecuterFactory

Parameters:

jasperReportsContext - the JasperReportsContext

dataset - the dataset containing the query, fields, etc

parameters - map of value parameters (instances of JRValueParameter) indexed by name

Returns:

a query executer

Throws:

JRException
