Public Attributes | |
| IFX_Allocator * | m_pAllocator |
| Special allocator pointer. NULL means to use default allocator. | |
Dynamic binary buffers designed for more efficient appending.
| CFX_BinaryBuf::CFX_BinaryBuf | ( | IFX_Allocator * | pAllocator = 0 | ) |
A default constructor creating an empty buffer.
| [in] | pAllocator | An allocator. Default value: NULL. |
| CFX_BinaryBuf::CFX_BinaryBuf | ( | FX_STRSIZE | size, |
| IFX_Allocator * | pAllocator = 0 |
||
| ) |
A default constructor creating an empty buffer.
| [in] | size | The size of buffer. |
| [in] | pAllocator | An allocator. Default value: NULL. |
| FX_BOOL CFX_BinaryBuf::AppendBlock | ( | const void * | pBuf, |
| FX_STRSIZE | size | ||
| ) |
Append a binary buffer block.
| [in] | pBuf | A pointer to a binary buffer block. |
| [in] | size | The size in bytes of the buffer block. |
Append a single byte.
| [in] | byte | A single byte. |
| FX_BOOL CFX_BinaryBuf::AppendFill | ( | FX_BYTE | byte, |
| FX_STRSIZE | count | ||
| ) |
Append a byte for specified number times. Not a byte-by-byte processing, but a byte filling processing internally.
| [in] | byte | The input byte. |
| [in] | count | Number of times. |
|
inline |
Append a non-buffered byte string.
| [in] | str | A no-buffered byte string. |
| void CFX_BinaryBuf::AttachData | ( | void * | pBuf, |
| FX_STRSIZE | size | ||
| ) |
Attach to a buffer (this buffer will belong to this object). The buffer must be allocated by FX_Alloc.
| [in] | pBuf | A pointer to a binary buffer. |
| [in] | size | The size in bytes of the buffer. |
| void CFX_BinaryBuf::Clear | ( | ) |
Set the binary buffer to be empty.
| FX_BOOL CFX_BinaryBuf::CopyData | ( | const void * | pBuf, |
| FX_STRSIZE | size | ||
| ) |
Copy from another buffer.
| [in] | pBuf | A pointer to a binary buffer. |
| [in] | size | The size in bytes of the input buffer. |
| void CFX_BinaryBuf::Delete | ( | int | start_index, |
| int | count | ||
| ) |
Delete a inter-zone buffer defining by parameters start_index and count in the binary buffer.
| [in] | start_index | Specifies the zero-based index of the start position to be deleted in the binary buffer. |
| [in] | count | Specifies the length in bytes to be deleted. |
| void CFX_BinaryBuf::DetachBuffer | ( | ) |
Detach the buffer. Just set buffer pointer to NULL, and set the binary buffer size to zero.
| FX_BOOL CFX_BinaryBuf::EstimateSize | ( | FX_STRSIZE | size, |
| FX_STRSIZE | alloc_step = 0 |
||
| ) |
Change the allocated buffer size, and set the allocation step if alloc_step is non-zero.
| [in] | size | The new size expected. |
| [in] | alloc_step | The new allocation step. If alloc_step is 0, then the allocation step will not change. Default value: 0. |
|
inline |
Get a byte pointer to the binary buffer.
| CFX_ByteStringC CFX_BinaryBuf::GetByteString | ( | ) | const |
Get a byte string from the buffer.
| void CFX_BinaryBuf::GetByteStringL | ( | CFX_ByteStringL & | str | ) | const |
Get a byte string from current buffer object.
| [out] | str | Receives the byte string from current buffer object. |
|
inline |

| [in] | size | The size in bytes of the buffer block. |
| void CFX_BinaryBuf::TakeOver | ( | CFX_BinaryBuf & | other | ) |
Takeover another buffer.
This function attaches to the source CFX_BinaryBuf object's buffer. The source CFX_BinaryBuf object has detached the buffer.
| [in] | other | A ref to CFX_BinaryBuf object. |
