Member Function Documentation

StringBuffer* jcpp::StringBuffer::append

(

Object *

obj

)

Note on all append/insert functions: the StringBuffer returned is the same as the one called. Note, because there are no methods on c++ objects (void *)s we can't call toString on Object. so printed form is a pointer.

StringBuffer* jcpp::StringBuffer::append	(	char *	str,
		int	len
	)

len is the number of characters appended, not counting the null character at the end of str. Note that str does NOT have to be null terminated at len+1.

StringBuffer* jcpp::StringBuffer::append

(

int

i

)

append the stringified int value.

StringBuffer* jcpp::StringBuffer::append

(

char

c

)

append a raw character.

StringBuffer* jcpp::StringBuffer::append	(	char *	str,
		int	offset,
		int	len
	)

the real workhorse of this class.

StringBuffer* jcpp::StringBuffer::append

(

double

d

)

append double as %21.18g

StringBuffer* jcpp::StringBuffer::append

(

float

f

)

append cast to double as %21.18g

StringBuffer* jcpp::StringBuffer::append

(

long

l

)

append as ld

int jcpp::StringBuffer::capacity

(

)

return the total size allocated for the string so far.

char jcpp::StringBuffer::charAt	(	int	index,
		int &	error
	)

return s[index]th character. if bad index, err -> -1, else 0.

StringBuffer* jcpp::StringBuffer::insert	(	int	offset,
		Object *	obj,
		int &	offsetError
	)

see java.

StringBuffer* jcpp::StringBuffer::insert	(	int	offset,
		char	c,
		int &	offsetError
	)

see java.

StringBuffer* jcpp::StringBuffer::insert	(	int	offset,
		char *	str,
		int &	offsetError
	)

see java.

StringBuffer* jcpp::StringBuffer::insert	(	int	offset,
		double	d,
		int &	offsetError
	)

see java.

StringBuffer* jcpp::StringBuffer::insert	(	int	offset,
		float	f,
		int &	offsetError
	)

see java.

StringBuffer* jcpp::StringBuffer::insert	(	int	offset,
		int	i,
		int &	offsetError
	)

see java.

StringBuffer* jcpp::StringBuffer::insert	(	int	offset,
		long	l,
		int &	offsetError
	)

see java.

int jcpp::StringBuffer::length

(

)

see java.

returns the current length (via strlen)

CFREE char* jcpp::StringBuffer::toString

(

)

Caller should free the pointer returned. Copies value into null terminated string.
