Constructor Detail

AbstractValueNode

public AbstractValueNode(T content)

Constructs a new Value Node.

Parameters:

content - the node content

Method Detail

eq

public EqualsNode eq(AbstractValueNode node)

Helper method used to easily create expressions such as "VALUE1 = VALUE2" without having to instantiate new objects. Note that the method is called "eq" in order not to be confused with the standard equals(Object).

Parameters:

node - the node that will be the second operand of the equals

Returns:

an EqualsNode that has the current object as the fist operand, and the parameter as the second operand

Since:

9.8RC1

notEq

public NotEqualsNode notEq(AbstractValueNode node)

Just as eq(AbstractValueNode), this method is a helper to create expressions without having to instantiate new objects.

Parameters:

node - the node that will be the second operand of the "not equals" node

Returns:

a NotEqualsNode composed of the current object as the first operand and the parameter as the second operand

Since:

9.8RC1

startsWith

public StartsWith startsWith(AbstractValueNode node)

Helper that allows to create StartsWith without having to instantiate new objects.

Parameters:

node - the node that will be the second operand of the "like" node

Returns:

a StartsWith where the current object is the first operand and the parameter is the second operand

Since:

9.8RC1

endsWith

public EndsWith endsWith(AbstractValueNode node)

Helper that allows to create EndsWith without having to instantiate new objects.

Parameters:

node - the node that will be the second operand of the "like" node

Returns:

a StartsWith where the current object is the first operand and the parameter is the second operand

Since:

10.2, 9.11.4

greaterThan

public GreaterThanNode greaterThan(AbstractValueNode node)

Helper that allows to create GreaterThanNode without having to instantiate new objects.

Parameters:

node - the node that will be the second operand of the ">=" node

Returns:

a GreaterThanNode where the current object is the first operand and the parameter is the second operand

Since:

9.9RC1

lesserThan

public LesserThanNode lesserThan(AbstractValueNode node)

Helper that allows to create LesserThanNode without having to instantiate new objects.

Parameters:

node - the node that will be the second operand of the "<=" node

Returns:

a LesserThanNode where the current object is the first operand and the parameter is the second operand

Since:

9.9RC1

in

public InNode in(Collection<AbstractValueNode> values)

Helper that allows to create InNode without having to instantiate new objects.

Parameters:

values - a collection of nodes

Returns:

a InNode where the current object is the first operand and the parameter is the second operand

Since:

9.10RC1

inStrings

public InNode inStrings(Collection<String> values)

Helper that allows to create InNode without having to instantiate new objects.

Parameters:

values - a collection of string

Returns:

a InNode where the current object is the first operand and the parameter is the second operand

Since:

9.10RC1

inSubQuery

public InSubQueryNode inSubQuery(String subQuery,
                                 Map<String,Object> parameters)

Helper that allows to create InSubQueryNode without having to instantiate new objects.

Parameters:

subQuery - the sub query in plain HQL language

parameters - the named parameters for the sub query

Returns:

a InSubQueryNode where the current object is the first operand and the sub query is the second operand

Since:

10.8RC1, 9.11.8

concat

public ConcatNode concat(AbstractValueNode node)

Helper that allows to create ConcatNode without having to instantiate new objects.

Parameters:

node - the node that will be the second operand of the concat

Returns:

an ConcatNode that has the current object as the fist operand, and the parameter as the second operand

Since:

10.8RC1, 9.11.8

getContent

public T getContent()

Returns:

the node content

equals

public boolean equals(Object o)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object
