Method Detail

deepCopy

public Parameters deepCopy()

addSubParameters

public Parameters addSubParameters(String newConnective)

Adds sub-parameters with a new connective. That is, the parameters will be grouped in parentheses in the generated query, e.g.: ... and (exp1 or exp2) and ..., assuming the old connective is "and", and the new connective is "or".

Parameters:

newConnective - New connective of the parameters.

Returns:

Sub-parameters with the given connective.

addNegatedParameters

public Parameters addNegatedParameters()

Adds negated parameters, by default with the "and" connective. These paremeters will be grouped in parentheses in the generated query and negated, e.g. ... not (exp1 and exp2) ...

Returns:

Negated sub paremters.

addNullRestriction

public void addNullRestriction(String propertyName,
                               boolean addAlias)

Adds IS NULL restriction.

Parameters:

propertyName - Property name.

addAlias - Positive if an alias to property name shall be added.

addNullRestriction

public void addNullRestriction(String alias,
                               String propertyName)

Adds IS NULL restriction.

Parameters:

propertyName - Property name.

addNotNullRestriction

public void addNotNullRestriction(String propertyName,
                                  boolean addAlias)

Adds IS NOT NULL restriction.

Parameters:

propertyName - Property name.

addAlias - Positive if an alias to property name shall be added.

addNotNullRestriction

public void addNotNullRestriction(String alias,
                                  String propertyName)

Adds IS NOT NULL restriction.

Parameters:

alias - the alias which should be added to the property name.
