Method Detail

as

public BooleanExpression as(Path<Boolean> alias)

Description copied from class: SimpleExpression

Create an alias for the expression

Overrides:

as in class ComparableExpression<Boolean>

Returns:

alias expression

as

public BooleanExpression as(String alias)

Description copied from class: SimpleExpression

Create an alias for the expression

Overrides:

as in class ComparableExpression<Boolean>

Returns:

alias expression

and

public BooleanExpression and(@Nullable
                             Predicate right)

Create a this && right expression

Returns an intersection of this and the given expression

Parameters:

right - right hand side of the union

Returns:

this && right

andAnyOf

public BooleanExpression andAnyOf(Predicate... predicates)

Create a this && any(predicates) expression

Returns an intersection of this and the union of the given predicates

Parameters:

predicates - union of predicates

Returns:

this && any(predicates)

not

public BooleanExpression not()

Create a !this expression

Returns a negation of this boolean expression

Specified by:

not in interface Predicate

Returns:

!this

or

public BooleanExpression or(@Nullable
                            Predicate right)

Create a this || right expression

Returns a union of this and the given expression

Parameters:

right - right hand side of the union

Returns:

this || right

orAllOf

public BooleanExpression orAllOf(Predicate... predicates)

Create a this or all(predicates) expression

Return a union of this and the intersection of the given predicates

Parameters:

predicates - intersection of predicates

Returns:

this or all(predicates)

isTrue

public BooleanExpression isTrue()

Create a this == true expression

Returns:

this == true

isFalse

public BooleanExpression isFalse()

Create a this == false expression

Returns:

Use expr.isNull() instead of expr.eq(null)

Overrides:

eq in class SimpleExpression<Boolean>

Parameters:

right - rhs of the comparison

Returns:

this == right
