ObjectOutputStream.PutField

public static abstract class ObjectOutputStream.PutField
extends Object

java.lang.Object
    java.io.ObjectOutputStream.PutField

提供对写入ObjectOutput的持久字段的编程访问。

摘要(Summary)

Public constructors
ObjectOutputStream.PutField()

公共方法(Public methods)
abstract void put(String name, float val)

将指定的浮点字段的值放入持久字段中。
abstract void put(String name, double val)

将指定的双字段的值放入持久字段中。
abstract void put(String name, int val)

将named int字段的值放入持久字段中。
abstract void put(String name, long val)

将指定长字段的值放入持久字段中。
abstract void put(String name, byte val)

将指定字节字段的值放入持久字段中。
abstract void put(String name, short val)

将命名的短字段的值放入持久字段中。
abstract void put(String name, Object val)

将名为Object的字段的值放入持久字段中。
abstract void put(String name, char val)

将指定的char字段的值放入持久字段中。
abstract void put(String name, boolean val)

将命名布尔字段的值放入持久字段中。
abstract void write(ObjectOutput out)

此方法在API级别1中已弃用。此方法不会以适当的格式写入此PutField对象所包含的值，并可能导致序列化流损坏。 编写PutField数据的正确方法是调用writeFields()方法。

参数(Parameters)
name String: the name of the serializable field

参数(Parameters)
out ObjectOutput: the stream to write the data and fields to
抛出异常(Throws)
IOException if I/O errors occur while writing to the underlying stream
IllegalArgumentException if the specified stream is not the same stream that produced this PutField object
