Methods of Class OUStringBuffer

OUStringBuffer
OUStringBuffer();

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

Summary
Constructs a string buffer with no characters in it and an initial capacity of 16 characters.
OUStringBuffer
OUStringBuffer(
const OUStringBuffer & value );

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

Summary
Allocates a new string buffer that contains the same sequence of characters as the string buffer argument.
Parameters
value 
a OStringBuffer.
OUStringBuffer
OUStringBuffer(
sal_Int32 length );

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

Summary
Constructs a string buffer with no characters in it and an initial capacity specified by the length argument.
Parameters
length 
the initial capacity.
OUStringBuffer
OUStringBuffer(
OUString value );

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

Summary
Constructs a string buffer so that it represents the same sequence of characters as the string argument.
Description
The initial capacity of the string buffer is 16 plus the length of the string argument.
Parameters
str 
the initial contents of the buffer.
operator=
OUStringBuffer & operator=(
const OUStringBuffer & value );

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

Summary
Assign to this a copy of value.
~OUStringBuffer
~OUStringBuffer();

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

Summary
Release the string data.
makeStringAndClear
OUString makeStringAndClear();

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

Summary
Fill the string data in the new string and clear the buffer.
Description
This method is more efficient than the contructor of the string. It does not copy the buffer.
Return
the string previously contained in the buffer.
getLength
sal_Int32 getLength();

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

Summary
Returns the length (character count) of this string buffer.
Return
the number of characters in this string buffer.
getCapacity
sal_Int32 getCapacity();

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

Summary
Returns the current capacity of the String buffer.
Description
The capacity is the amount of storage available for newly inserted characters. The real buffer size is 2 bytes longer, because all strings are 0 terminated.
Return
the current capacity of this string buffer.
ensureCapacity
void ensureCapacity(
sal_Int32 minimumCapacity );

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

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
minimumCapacity 
the minimum desired capacity.
setLength
void setLength(
sal_Int32 newLength );

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

Summary
Sets the length of this String buffer.
Description
If the newLength argument is less than the current length of the string buffer, the string buffer is truncated to contain exactly the number of characters given by the newLength argument.

If the newLength argument is greater than or equal to the current length, sufficient null characters ('\u0000') are appended to the string buffer so that length becomes the newLength argument.

The newLength argument must be greater than or equal to 0.

Parameters
newLength 
the new length of the buffer.
charAt
sal_Unicode charAt(
sal_Int32 index );

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

Summary

Description
The first character of a string buffer is at index 0, the next at index 1, and so on, for array indexing.

The index argument must be greater than or equal to 0, and less than the length of this string buffer.

Parameters
index 
the index of the desired character.
Return
the character at the specified index of this string buffer.
