Constructs a new bufferStore.

Constructs a new bufferStore and initializes its content.

Parameters:

buf	Pointer to data for initialization.
len	Length of data for initialization.

Destroys a bufferStore instance.

Constructs a new bufferStore and initializes its content.

Parameters:

b	A bufferStore, whose content is used for initialization.

Copies a bufferStore.

[const]

Retrieves the length of a bufferStore.

Returns: The current length of the contents in bytes.

[const]

Retrieves the byte at index pos.

Parameters:

pos	The index of the byte to retrieve.

Returns: The value of the byte at index pos

[const]

Retrieves the word at index pos.

Parameters:

pos	The index of the word to retrieve.

Returns: The value of the word at index pos

[const]

Retrieves the dword at index pos.

Parameters:

pos	The index of the dword to retrieve.

Returns: The value of the dword at index pos

[const]

Retrieves the characters at index pos.

Parameters:

pos	The index of the characters to retrieve.

Returns: A pointer to characters at index pos

Removes bytes from the start of the buffer.

Parameters:

len	Number of bytes to remove.

Prints a dump of the content.

Mainly used for debugging purposes.

Parameters:

s	The stream to write to.
b	The bufferStore do be dumped.

Returns: The stream.

[const]

Tests if the bufferStore is empty.

Returns: true, if the bufferStore is empty. false, if it contains data.

Initializes the bufferStore.

All data is removed, the length is reset to 0.

Initializes the bufferStore with a given data.

Parameters:

buf	Pointer to data to initialize from.
len	Length of data.

Appends a byte to the content of this instance.

Parameters:

c	The byte to append.

Appends a word to the content of this instance.

Parameters:

w	The word to append.

Appends a dword to the content of this instance.

Parameters:

dw	The dword to append.

Appends a string to the content of this instance.

The trailing zero byte is not copied to the content.

Parameters:

s	The string to append.

Appends a string to the content of this instance.

The trailing zero byte is copied to the content.

Parameters:

s	The string to append.

Appends data to the content of this instance.

Parameters:

buf	The data to append.
len	Length of data.

Appends data to the content of this instance.

Parameters:

b	The bufferStore whose content to append.
maxLen	Length of content to append. If maxLen is less than 0 or greater than the current length of b , then the whole content of b is appended.

Truncates the buffer. If the buffer is smaller, does nothing.

Parameters:

newLen

The new length of the buffer.

Prepends a byte to the content of this instance.

Parameters:

c	The byte to append.

Prepends a word to the content of this instance.

Parameters:

w	The word to append.
