Constructor Detail

NumberOperand

public NumberOperand(QueryParameter queryParameter)

Creates a new operand instance.

Parameters:

queryParameter - the left operand for all predicates to be built

NumberOperand

public NumberOperand(QueryParameter queryParameter,
                     ConstructionInterceptor constructionInterceptor)

Creates a new operand instance.

Parameters:

queryParameter - the left operand for all predicates to be built

constructionInterceptor - the interceptor to be invoked upon construction of predicates

Method Detail

lessThan

public final Predicate lessThan(T referenceValue)

Builds a predicate representing a queryParameter < referenceValue comparison.

Parameters:

referenceValue - the reference value used for the comparison

Returns:

the new predicate instance

lessThanOrEq

public final Predicate lessThanOrEq(T referenceValue)

Builds a predicate representing a queryParameter <= referenceValue comparison.

Parameters:

referenceValue - the reference value used for the comparison

Returns:

the new predicate instance

greaterThan

public final Predicate greaterThan(T referenceValue)

Builds a predicate representing a queryParameter > referenceValue comparison.

Parameters:

referenceValue - the reference value used for the comparison

Returns:

the new predicate instance

greaterThanOrEq

public final Predicate greaterThanOrEq(T referenceValue)

Builds a predicate representing a queryParameter >= referenceValue comparison.

Parameters:

referenceValue - the reference value used for the comparison

Returns:

the new predicate instance
