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。

Summary

Public constructors

ObjectOutputStream.PutField()

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。

Added in API level 1
void put (String name, 
                double val)

将指定的双字段的值放入持久字段中。

Parameters
name String: the name of the serializable field
val double: the value to assign to the field
Throws
IllegalArgumentException if name does not match the name of a serializable field for the class whose fields are being written, or if the type of the named field is not double

put

Added in API level 1

                long val)

将指定长字段的值放入持久字段中。

Parameters
name String: the name of the serializable field
val long: the value to assign to the field
Throws
IllegalArgumentException if name does not match the name of a serializable field for the class whose fields are being written, or if the type of the named field is not long

put

Added in API level 1
void put (String name, 
                byte val)

将指定字节字段的值放入持久字段中。

Parameters
name String: the name of the serializable field
val byte: the value to assign to the field
Throws
IllegalArgumentException if name does not match the name of a serializable field for the class whose fields are being written, or if the type of the named field is not byte

put

Added in API level 1
void put (String name, 
                short val)

将命名的短字段的值放入持久字段中。

Parameters
name String: the name of the serializable field
val short: the value to assign to the field
Throws
IllegalArgumentException if name does not match the name of a serializable field for the class whose fields are being written, or if the type of the named field is not short

put

Added in API level 1
void put (String name, 
                Object val)

将名为Object的字段的值放入持久字段中。

Parameters
name String: the name of the serializable field
val Object: the value to assign to the field (which may be null)
Throws
IllegalArgumentException if name does not match the name of a serializable field for the class whose fields are being written, or if the type of the named field is not a reference type

put

Added in API level 1
void put (String name, 
                char val)

将指定的char字段的值放入持久字段中。

Parameters
name String: the name of the serializable field
val char: the value to assign to the field
Throws
IllegalArgumentException if name does not match the name of a serializable field for the class whose fields are being written, or if the type of the named field is not char

put

Added in API level 1

                boolean val)

将命名布尔字段的值放入持久字段中。

Parameters
name String: the name of the serializable field
val boolean: the value to assign to the field
Throws
IllegalArgumentException if name does not match the name of a serializable field for the class whose fields are being written, or if the type of the named field is not boolean

write

Added in API level 1
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。

将数据和字段写入指定的ObjectOutput流,该流必须与生成此 PutField对象的流相同。

Parameters
out ObjectOutput: the stream to write the data and fields to
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

Hooray!
