Method Detail

getName

public String getName()

The internal parameter name. This will be the name of the data-row field by which the parameter's value can be accessed.

Specified by:

getName in interface ParameterDefinitionEntry

Returns:

the parameter name.

setParameterAttribute

public void setParameterAttribute(String domain,
                                  String name,
                                  String value)

getParameterAttribute

public String getParameterAttribute(String domain,
                                    String name)

getParameterAttribute

public String getParameterAttribute(String domain,
                                    String name,
                                    ParameterContext parameterContext)

Description copied from interface: ParameterDefinitionEntry

Returns the parameter label. This is optional, but provides a sensible default for auto-generated parameter pages.

Specified by:

getParameterAttribute in interface ParameterDefinitionEntry

Parameters:

domain - the parameter domain (namespace)

name - the name of the parameter attribute

parameterContext - the context from where to aquire the locale for the label.

Returns:

the label.

getParameterAttributeNamespaces

public String[] getParameterAttributeNamespaces()

Specified by:

getParameterAttributeNamespaces in interface ParameterDefinitionEntry

getParameterAttributeNames

public String[] getParameterAttributeNames(String domain)

Specified by:

getParameterAttributeNames in interface ParameterDefinitionEntry

isMandatory

public boolean isMandatory()

Provides a hint to the parameter validator, whether this value needs to have a selected value.

Specified by:

isMandatory in interface ParameterDefinitionEntry

Returns:

true, if the parameter must have a valid value, false otherwise.

setMandatory

public void setMandatory(boolean mandatory)

getValueType

public Class getValueType()

Returns the parameter value type. This is used to perform a simple validation on the incoming untrusted data and converts any incoming text value into a sensible default.

Specified by:

getValueType in interface ParameterDefinitionEntry

Returns:

setValueType

public void setValueType(Class valueType)

getDefaultValue

public Object getDefaultValue()

getDefaultValue

public Object getDefaultValue(ParameterContext context)
                       throws ReportDataFactoryException

Specified by:

getDefaultValue in interface ParameterDefinitionEntry

Throws:

ReportDataFactoryException

setDefaultValue

public void setDefaultValue(Object defaultValue)

clone

public Object clone()
             throws CloneNotSupportedException

Specified by:

clone in interface ParameterDefinitionEntry

Overrides:

clone in class Object

Throws:

CloneNotSupportedException

setHidden

public void setHidden(boolean hidden)

isDeprecated

public boolean isDeprecated()

setDeprecated

public void setDeprecated(boolean deprecated)

getRole
