.PP 
.SS "void sc::TwoBodyIntCCA::compute_shell (int, int, int, int)\fC [virtual]\fP"

.PP
Given four shell indices, integrals will be computed and placed in the buffer\&. The first two indices correspond to electron 1 and the second two indices correspond to electron 2\&. 
.PP
Implements \fBsc::TwoBodyInt\fP\&.
.SS "int sc::TwoBodyIntCCA::log2_shell_bound (int, int, int, int)\fC [virtual]\fP"

.PP
Return log base 2 of the maximum magnitude of any integral in a shell block obtained from compute_shell\&. An index of -1 for any argument indicates any shell\&. 
.br
 
.PP
Implements \fBsc::TwoBodyInt\fP\&.
.SS "int sc::TwoBodyIntCCA::redundant () const\fC [inline]\fP, \fC [virtual]\fP"

.PP
If redundant is true, then keep redundant integrals in the buffer\&. The default is true\&. 
.PP
Reimplemented from \fBsc::TwoBodyInt\fP\&.
