Method Detail

name

public StringOperand<String> name()

Returns an operand which allows to build predicates testing for the name part of properties.

Returns:

a name-specific predicate operand

undefined

public Predicate undefined(String propertyName)

Returns a predicate representing an undefined property predicate

Parameters:

propertyName - property which must be undefined

Returns:

a new predicate instance

undefined

public Predicate undefined(PropertyName<?> propertyName)

Returns a predicate representing an undefined property predicate

Parameters:

propertyName - property which must be undefined

Returns:

a new predicate instance

value

public StringOperand<String> value()

Returns an operand which allows to build predicates testing for the value part of properties.

Returns:

a value-specific predicate operand

nameAndValueEq

public <V> Predicate nameAndValueEq(PropertyName<V> expectedPropertyName,
                                    V expectedValue)

Returns a predicate testing for properties with the given property name and the given value.

Type Parameters:

V - the type of the property value

Parameters:

expectedPropertyName - the expected property name

expectedValue - the expected property value

Returns:

the new predicate instance

nameAndValueEq

public Predicate nameAndValueEq(String expectedName,
                                String expectedValue)

Returns a predicate testing for properties with the given name and the given value.

Parameters:

expectedName - the expected property name

expectedValue - the expected property value

Returns:

the new predicate instance
