Method Detail

readBoolean

public static boolean readBoolean(android.os.Parcel in)

Read a boolean value from the Parcel.

This method reads one byte and returns true if the read value is not 0.

Parameters:

in - Parcel to read from.

Returns:

A boolean value read from the Parcel.

writeBoolean

public static void writeBoolean(android.os.Parcel out,
                                boolean value)

Write a boolean value into the Parcel.

This method writes (byte)1 when value is true and writes (byte)0 when value is false.

Parameters:

out - Parcel to write into.

value - A boolean value to write.

readChar

public static char readChar(android.os.Parcel in)

Read a char value from the Parcel.

This method reads one int and converts the read value into a char value.

Parameters:

in - Parcel to read from.

Returns:

A char value read from the Parcel.

writeChar

public static void writeChar(android.os.Parcel out,
                             char value)

Write a char value into the Parcel.

This method writes the given char value as int.

Parameters:

out - Parcel to write into.

value - A char value to write.

readStringWithPresenceFlag

public static String readStringWithPresenceFlag(android.os.Parcel in)

Read a String object from the Parcel.

First, this method reads a boolean value from the Parcel using readBoolean(Parcel) method. When the read boolean value is true, this method executes in.readString() and returns the value. Otherwise, when the read boolean value is false, this method returns null.

Parameters:

in - Parcel to read from.

Returns:

String object or null.

writeStringWithPresenceFlag

public static void writeStringWithPresenceFlag(android.os.Parcel out,
                                               String value)

Write a String object with a presence flag into the Parcel.

First, this method checks whether value is null or not. When null, this method writes false into the Parcel by calling writeBoolean(false) and does nothing any more. Otherwise, when not null, this method writes true by calling writeBoolean(true) and then writes the String object by calling out.writeString(value).

Parameters:

out - Parcel to write into.

value - A String object to write.

readSerializableWithPresenceFlag

public static Serializable readSerializableWithPresenceFlag(android.os.Parcel in)

Read a Serializable object from the Parcel.

First, this method reads a boolean value from the Parcel using readBoolean(Parcel) method. When the read boolean value is true, this method executes in.readSerializable() and returns the value. Otherwise, when the read boolean value is false, this method returns null.

Parameters:

in - Parcel to read from.

Returns:

Serializable object or null.

writeSerializableWithPresenceFlag

public static void writeSerializableWithPresenceFlag(android.os.Parcel out,
                                                     Serializable value)

Write a Serializable object with a presence flag into the Parcel.

First, this method checks whether value is null or not. When null, this method writes false into the Parcel by calling writeBoolean(false) and does nothing any more. Otherwise, when not null, this method writes true by calling writeBoolean(true) and then writes the Serializable object by calling out.writeSerializable(value).

Parameters:

out - Parcel to write into.

value - A String object to write.
