Member Function Documentation

void Clasp::StreamSource::error ( const char *  err ) const

inline

Here is the call graph for this function:

unsigned Clasp::StreamSource::line ( ) const

inline

Returns the number of matched EOLs + 1.

bool Clasp::StreamSource::match ( char  c )

inline

Consumes next character if equal to c.

bool Clasp::StreamSource::matchEol

(

)

Consumes next character(s) if equal to EOL.

Consumes the next character if it is either '
' or '' and increments the internal line counter.

Note

If next char is '', the function will also consume a following '
' (i.e. matchEol also matches CR/LF).

Here is the call graph for this function:

char Clasp::StreamSource::operator* ( )

inline

Returns the character at the current reading-position.

StreamSource& Clasp::StreamSource::operator++ ( )

inline

Advances the current reading-position.

bool Clasp::StreamSource::parseInt

(

int &

val

)

Reads a base-10 integer.

Precondition

system uses ASCII

Here is the call graph for this function:

bool Clasp::StreamSource::parseInt	(	int &	val,
		int	min,
		int	max
	)

Here is the call graph for this function:

int Clasp::StreamSource::parseInt ( int  min, int  max, const char *  err  )

inline

Here is the call graph for this function:

bool Clasp::StreamSource::parseInt64

(

int64 &

val

)

Here is the call graph for this function:

bool Clasp::StreamSource::skipSpace ( )

inline

Skips horizontal white-space.

Here is the call graph for this function:

bool Clasp::StreamSource::skipWhite ( )

inline

Skips horizontal and vertical white-space.

Here is the call graph for this function:
