of

public static ExistsPredicate of(TypedSubQuery<?> subQuery,
 boolean negative)

not

public Predicate not()

从接口复制的说明: Predicate

This function will be deleted in 1.0.0, please use the static method Predicate.not(Predicate)

precedence

public int precedence()

accept

public void accept(@NotNull
 @NotNull AstVisitor visitor)

renderTo

public void renderTo(@NotNull
 @NotNull SqlBuilder builder)

equals

public boolean equals(Object o)

覆盖:

equals 在类中 Object

hashCode

public int hashCode()

覆盖:

hashCode 在类中 Object

determineHasVirtualPredicate

protected boolean determineHasVirtualPredicate()

指定者:

determineHasVirtualPredicate 在类中 AbstractExpression<Boolean>

onResolveVirtualPredicate

protected Ast onResolveVirtualPredicate(AstContext ctx)

指定者:

onResolveVirtualPredicate 在类中 AbstractExpression<Boolean>
