Detailed Description

A BMessage is a bundle of structured information. Every BMessage contains a command constant and some number of data fields.

Constructor & Destructor Documentation

BMessage ( )

Creates a new BMessage object.

BMessage ( uint32 pwhat ) [explicit]

Creates a new BMessage object that has the given command constant.

Parameters:

pwhat command constant

BMessage ( const BMessage & msg )

Creates a new BMessage object hat's a copy of another BMessage. If it's a copy, the new object contains the same command constant and data fields as message.

Parameters:

msg BMessage

~BMessage ( ) [virtual]

Frees all memory allocated to hold message data. If the message sender is expecting a reply but hasn't received one, a default reply (with B_NO_REPLY as the what data member) is sent before the message is destroyed.
The system retains ownership of the messages it delivers to you. Each message loop routinely deletes delivered BMessages after the application is finished responding to them.

Member Function Documentation

status_t AddAtom ( const char * name,

const atom< BAtom > & obj

)

status_t AddAtom ( const char * name,

const BAtom * atm

)

status_t AddAtomRef ( const char * name,

const atomref< BAtom > & obj

)

status_t AddAtomRef ( const char * name,

)

status_t AddAtomRef ( const char * name,

const BAtom * atm

)

status_t AddBool ( const char * name,

bool a_boolean

)

Most of the other functions are variants of AddData() that hard-code the field's type. For example, AddFloat() assigns the type B_FLOAT_TYPE; AddBool() assigns B_BOOL_TYPE, and so on.

Parameters:

name

a_boolean

status_t AddData ( const char * name,

type_code type,

const void * data,

ssize_t numBytes,

bool is_fixed_size = true,

int32 count = 1

)

These functions add data to the field named name and assign a data type to the field. Field names can be no longer than 255 characters. If more than one item of data is added under the same name, the BMessage creates an array of data for that name. Each time you add another value (to the same name), the value is added to the end of the array - you can't add a value at a specific index. A given field can only store one type of data.
Copies numBytes of data into the field, and assigns the data a type code. It copies whatever the param_ref data pointer points to. For example, if you want to add a string of characters to the message, data should be the string pointer (char *). If you want to add only the string pointer, not the characters themselves, data should be a pointer to the pointer (char **). The assigned type must be a specific data type; it should not be B_ANY_TYPE.
When you call AddData() to place the first item in an array under a new name, you can provide it with two arguments, fixedSize and numItems, that will improve the object's efficiency. If the fixedSize flag is true, each item in the array must have the same number of bytes; if the flag is false, items can vary in size. numItems tells the object to pre-allocate storage for some number of items. This isn't a limit - you can add more than numItems to the field.

Parameters:

name

type

data

numBytes

is_fixed_size (dafault is true)

count (default is 1)

Most of the other functions are variants of AddData() that hard-code the field's type. For example, AddFloat() assigns the type B_FLOAT_TYPE; AddBool() assigns B_BOOL_TYPE, and so on.
There's no limit on the number of named fields a message can contain or on the size of a field's data. However, since the search is linear, combing through a very long list of names to find a particular piece of data may be inefficient. Also, because of the amount of data that must be moved, an extremely large message can slow the delivery mechanism. It's sometimes better to put some of the information in a common location (a file, a private clipboard, a shared area of memory) and just refer to it in the message.

status_t AddDouble ( const char * name,

double a_double

)

status_t AddFlat ( const char * name,

const BFlattenable * obj,

int32 count = 1

)

Flattens an obj (by calling its Flatten() function) and adds the flat data to the message. It calls the object's TypeCode() function to learn the type code it should associate with the data. Objects that are added through AddFlat() must inherit from BFlattenable (defined in the Support Kit).
You can also provide a numItems hint to AddFlat() when you call it to set up a new array AddFlat() calls the object's IsFixedSize() function to discover whether all items in the array will be the same size.

Returns:
B_ERROR if the data is too massive to be added to the message
B_BAD_TYPE if the data can't be added to an existing array because it's the wrong type
B_NO_MEMORY if the BMessage can't get enough memory to hold the data
B_BAD_VALUE if the proposed name for the data is longer than 255 bytes.
If all goes well, they return B_OK.

status_t AddFloat ( const char * name,

float a_float

)

status_t AddInt16 ( const char * name,

int16 val

)

status_t AddInt32 ( const char * name,

int32 val

)

Takes an int32 or uint32.

Parameters:

name

val

status_t AddInt64 ( const char * name,

int64 val

)

status_t AddInt8 ( const char * name,

int8 val

)

status_t AddMessage ( const char * name,

const BMessage * msg

)

AddMessage() adds one BMessage to another.

status_t AddMessenger ( const char * name,

BMessenger messenger

)

Takes a BMessenger object.

Parameters:

name

messenger

status_t AddPoint ( const char * name,

BPoint a_point

)

status_t AddPointer ( const char * name,

const void * obj

)

Adds only the pointer it's passed, not the data it points to.
To accomplish the same thing, AddData() would take a pointer to the pointer. (The pointer will be valid only locally; it won't be useful to a remote destination.)

Parameters:

name

obj

status_t AddRect ( const char * name,

BRect r

)

Add Rectangle.

Parameters:

name

r Rectangle

status_t AddRef ( const char * name,

const entry_ref * ref

)

Similarly, AddRef() adds the pointed to entry_ref structure to the message (and the variable-length name that's one of the elements of the structure);

status_t AddRGBColor ( const char * name,

rgb_color a_color,

type_code type = B_RGB_COLOR_TYPE

)

status_t AddSpecifier ( const BMessage * spec )
