file

Note

file is only available in the scripts if the application registers support for it.

Script example:

  file f;
  // Open the file in 'read' mode
  if( f.open("file.txt", "r") >= 0 ) 
  {
      // Read the whole file into the string buffer
      string str = f.readString(f.getSize()); 
      f.close();
  }

Methods

int open(const string &in filename, const string &in mode)

Opens a file. The mode can be "r" for reading, "w" for writing, or "a" for appending.

If the file couldn't be opened, a negative value is returned.

int close()

Closes the file.

If no file is open, a negative value is returned.

int getSize() const

Returns the size of the file, or a negative value if no file is open.

bool isEndOfFile() const

Returns true if the current position is at the end of the file.

string readString(uint length)

Reads length bytes into a string and returns it.

string readLine()

Reads until a new line character, e.g. '\n', or end-of-file and returns the string. The new line character is also returned in the string.

int64 readInt(uint bytes)

Reads bytes as a signed integer number.

uint64 readUInt(uint bytes)

Reads bytes as an unsigned integer number.

float readFloat()

Reads 4 bytes as a float number.

double readDouble()

Reads 8 bytes as a double number.

int writeString(const string &in str)

Writes the bytes of the string into the file.

Returns the number of bytes written, or a negative value on error.

int writeInt(int64 value, uint bytes)

Writes bytes as a signed integer value.

Returns the number of bytes written, or a negative value on error.

int writeUInt(uint64 value, uint bytes)

Writes bytes as an unsigned integer value.

Returns the number of bytes written, or a negative value on error.

int writeFloat(float value)

Writes 4 bytes as a float value.

Returns the number of bytes written, or a negative value on error.

int writeDouble(double value)

Writes 8 bytes as a double value.

Returns the number of bytes written, or a negative value on error.

int getPos() const

Returns the current position in the file, or a negative value on error.

int setPos(int pos)

Sets the current position in the file. Returns the previous position or a negative value on error.

int movePos(int delta)

Moves the position delta bytes relative to the current position. Returns the previous position or a negative value on error.

Properties

bool mostSignificantByteFirst

This property should be set to true if the most significant bit should be read or written first in the methods that reads/writes numbers.

It is set to false by default, which is the standard on most platforms.
