Method Detail

getName

String getName()

The name of the field.

The name is any of these:

• The formal name of the field, if it is a physical table/view field
• The alias of an aliased field
• A generated / unspecified value for any other expression
• The name of a parameter if it is a named Param

The Param's value for getName() coincides with getParamName()

Specified by:

getName in interface Field<T>

Specified by:

getName in interface NamedQueryPart

getParamName

String getParamName()

The parameter name. This name is useful for two things:

• Named parameters in frameworks that support them, such as Spring's JdbcTemplate
• Accessing the parameter from the Query API, with Query.getParam(String), Query.getParams()

getValue

T getValue()

Get the parameter's underlying value. This returns null if no value has been set yet.

setValue

void setValue(T value)

Set the parameter's underlying value. This is the same as setConverted(Object), but ensures generic type-safety.

See Also:

setConverted(Object)

setConverted

void setConverted(Object value)
                  throws DataTypeException

Sets a converted value, using this Param's underlying DataType, obtained from NamedTypeProviderQueryPart.getDataType()

Throws:

DataTypeException - If value cannot be converted into this parameter's data type.

DataType.convert(Object), Convert.convert(Object, Class)
