接口 JsonWriter.ValueProcessor<T>

类型参数:

T - the value type

封闭接口:

JsonWriter<T>

函数接口:

这是一个函数接口, 因此可用作 lambda 表达式或方法引用的赋值目标。

@FunctionalInterface
public static interface JsonWriter.ValueProcessor<T>

Callback interface that can be applied to JsonWriter.Members to process values before they are written. Typically used to filter values, for example to reduce superfluous information or sanitize sensitive data.

方法详细资料

processValue

T processValue(JsonWriter.MemberPath path,
 T value)

Process the value at the given path.

参数:

path - the path of the member containing the value

value - the value being written (may be null)

返回:

the processed value

whenHasUnescapedPath

default JsonWriter.ValueProcessor<T> whenHasUnescapedPath(String path)

Return a new processor from this one that only applied to members with the given path (ignoring escape characters).

参数:

path - the patch to match

返回:

a new JsonWriter.ValueProcessor that only applies when the path matches

whenHasPath

default JsonWriter.ValueProcessor<T> whenHasPath(String path)

Return a new processor from this one that only applied to members with the given path.

参数:

path - the patch to match

返回:

a new JsonWriter.ValueProcessor that only applies when the path matches

whenHasPath

default JsonWriter.ValueProcessor<T> whenHasPath(Predicate<JsonWriter.MemberPath> predicate)

Return a new processor from this one that only applied to members that match the given path predicate.

参数:

predicate - the predicate that must match

返回:

a new JsonWriter.ValueProcessor that only applies when the predicate matches

whenInstanceOf

default JsonWriter.ValueProcessor<T> whenInstanceOf(Class<?> type)

Return a new processor from this one that only applies to member with values of the given type.

参数:

type - the type that must match

返回:

a new JsonWriter.ValueProcessor that only applies when value is the given type.

when

default JsonWriter.ValueProcessor<T> when(Predicate<T> predicate)

Return a new processor from this one that only applies to member with values that match the given predicate.

参数:

predicate - the predicate that must match

返回:

a new JsonWriter.ValueProcessor that only applies when the predicate matches

of
