dbi.util.StringWriter

class SqlStringWriter_ (bool AllowCustomAlloc = false);

Utility class for writing sql statement to a string buffer

size_t growSize ;

The string grow size

char[] reserve (size_t sz);

Ensures that the buffer has space to write sz elements and does appropriate allocation as necessary.

Params:

size_t sz

the buffer length to reserve

Returns:

TypeOfThis backup (size_t n = 1);

Decrements the buffer index essentially erasing data that was written

Params:

size_t n

the number of characters to backup

Returns:

TypeOfThis correct (char c);

Replaces the previously written character with the provided character c

size_t length ();

Returns:
The current length of the array that has been written to (not the size of the buffer).

alias opCall ;

Alias for write

TypeOfThis write (char[][] strs...);

TypeOfThis write (size_t delegate(void[] buf) writeDg);

Exposes raw buffer for writing

Params:

size_t delegate(void[] buf) writeDg

the delegate which will write to the exposed buffer. this delegate must return the number of bytes written.

TypeOfThis write (size_t reserveSize, size_t delegate(void[] buf) writeDg);

Reserves a certain amount of space in the write buffer and exposes that raw buffer to writing

Params:

size_t delegate(void[] buf) writeDg

the delegate which will write to the exposed buffer. this delegate must return the number of bytes written.

void opCatAssign (char ch);

Appends to the string

void opCatAssign (char[] str);

Appends to the string

char[] get ();

Returns:
The string that has been written. (Essentially returns a slice of the string buffer up to the last character that has been written.)

void reset ();

Resets buffer for reuse

void free ();

Frees memory that has been allocated
