rtl_stringbuffer_ensureCapacity

extern "C"
void rtl_stringbuffer_ensureCapacity(

rtl_String * *	This,
sal_Int32 *	capacity,
sal_Int32	minimumCapacity );

virtual	abstract	const	volatile	template	static	inline	C-linkage
NO	NO	NO	NO	NO	NO	NO	YES

Summary

Ensures that the capacity of the buffer is at least equal to the specified minimum.

Description

If the current capacity of this string buffer is less than the argument, then a new internal buffer is allocated with greater capacity. The new capacity is the larger of:

• The minimumCapacity argument.
• Twice the old capacity, plus 2.

If the minimumCapacity argument is nonpositive, this method takes no action and simply returns.

Parameters

capacity	in: old capicity, out: new capacity.
minimumCapacity	the minimum desired capacity.

rtl_stringbuffer_insert

extern "C"
void rtl_stringbuffer_insert(

rtl_String * *	This,
sal_Int32 *	capacity,
sal_Int32	offset,
const sal_Char *	str,
sal_Int32	len );

virtual	abstract	const	volatile	template	static	inline	C-linkage
NO	NO	NO	NO	NO	NO	NO	YES

Summary

Inserts the string representation of the char array argument into this string buffer.

Description

The characters of the array argument are inserted into the contents of this string buffer at the position indicated by offset. The length of this string buffer increases by the length of the argument.

Parameters

capacity	the capacity of the string buffer
offset	the offset.
ch	a character array.
len	the number of characters to append.

Return

this string buffer.

rtl_stringbuffer_newFromStr_WithLength

extern "C"
void rtl_stringbuffer_newFromStr_WithLength(

rtl_String * *	newStr,
const sal_Char *	value,
sal_Int32	count );

virtual	abstract	const	volatile	template	static	inline	C-linkage
NO	NO	NO	NO	NO	NO	NO	YES

Summary

Allocates a new String that contains characters from the character array argument.

Description

The count argument specifies the length of the array. The initial capacity of the string buffer is 16 plus the length of the string argument.

Parameters

newStr	out parameter, contains the new string. The reference count is 1.
value	the initial value of the string.
count	the length of value.

rtl_stringbuffer_newFromStringBuffer

extern "C"
sal_Int32 rtl_stringbuffer_newFromStringBuffer(

rtl_String * *	newStr,
sal_Int32	capacity,
rtl_String *	olsStr );

virtual	abstract	const	volatile	template	static	inline	C-linkage
NO	NO	NO	NO	NO	NO	NO	YES

Summary

Allocates a new String that contains the same sequence of characters as the string argument.

Description

The initial capacity is the larger of:

• The bufferLen argument.
• The length of the string argument.

Parameters

newStr	out parameter, contains the new string. The reference count is 1.
capacity	the initial len of the string buffer.
oldStr	the initial value of the string.

Return

the new capacity of the string buffer
