class MemoryXFile

A file in the memory.

Inheritance:

Public Fields

MemoryXFileList* memory

The memory

int position

The position in the memory

int size

The size of the memory

int total_size

The total size of the memory, including allocated buffer

int buffer_size

Minimal number of bytes that will be allocated when writing

Public Methods

MemoryXFile(int buffer_format_size_=256)

Create a read-write file from nothing

MemoryXFile(MemoryXFileList* memory_, int size_=-1, int buffer_format_size_=256)

Give a MemoryXFileList for the memory.

MemoryXFile(void* memory_, int size_, int buffer_format_size_=256)

Give a pointer for the memory.

void concat()

Concat all the memory in one node.

virtual int scanf(const char* format, void* ptr)

Warning: this method call the concat function, and therefore could take time if you do intensive read/write.

void operator delete(void* ptr)

Documentation

A file in the memory. Note that the MemoryXFile is a read-write file! When writing, data is buffered (to avoid reallocating blocks of small sizes!).

Options:

"buffer size"

int

buffer size for writing

[65536]

MemoryXFileList* memory

The memory

int position

The position in the memory

int size

The size of the memory

int total_size

The total size of the memory, including allocated buffer

int buffer_size

Minimal number of bytes that will be allocated when writing

MemoryXFile(int buffer_format_size_=256)

Create a read-write file from nothing

MemoryXFile(MemoryXFileList* memory_, int size_=-1, int buffer_format_size_=256)

Give a MemoryXFileList for the memory. A new list is created, but the memory in the nodes are not copied. If the size that you want to be readable is less than the sum of the n in the field of the MemoryXFileList, you can provide it in size_

MemoryXFile(void* memory_, int size_, int buffer_format_size_=256)

Give a pointer for the memory. (No copy is done!)

void concat()

Concat all the memory in one node. Add a null character at the end. This null character is useful for sscanf in the scanf method.

virtual int scanf(const char* format, void* ptr)

Warning: this method call the concat function, and therefore could take time if you do intensive read/write.

This class has no child classes.
