Detailed Description

BundleReader is an interface for reading sequence of bytes.

Member Function Documentation

ssize_t read ( void *  ptr,
ssize_t  size,
ssize_t  count 
)

Reads an array of elements.

The pointer to the memory to copy into. The available size should be at least bytes. The size of each element to be read, in bytes. The number of elements to read. The number of elements read.

char* readLine ( int  num,
char *  line 
)

Reads a line from the buffer.

The amount of lines to reads The result The result, same as line.

bool eof ( )

Check if the file pointer is at the end of the buffer or not.

Returns true if the end of the buffer has been reached, otherwise returns false.

ssize_t tell ( )

Returns the position of the file pointer.

The position of the file pointer

bool seek ( long int  offset,
int  origin 
)

Sets the position of the file pointer.

The offset The base position. The result of the seek

bool rewind ( )

Sets the file pointer at the start of the file.

The result of the rewind.

bool read ( T *  ptr)

Read binary typed value.

The specified type pointer. The result of the read.

bool readArray ( unsigned int *  length,
std::vector< T > *  values 
)

Read binary typed value array.

Length of the array Output array to store the result

std::string readString ( )

Read the string from the bundle, first read length, then read string text.

The result string.

bool readMatrix ( float *  m)

Read the matrix.

the matrix type must be the 4*4 float matrix The result matrix. The result of the reading.
