示例1: getCompoundName
bool JsonItem::getCompoundName ( SafeBuf &nameBuf ) {
// reset, but don't free mem etc. just set m_length to 0
nameBuf.reset();
// get its full compound name like "meta.twitter.title"
JsonItem *p = this;//ji;
char *lastName = NULL;
char *nameArray[20];
int32_t numNames = 0;
for ( ; p ; p = p->m_parent ) {
// empty name?
if ( ! p->m_name ) continue;
if ( ! p->m_name[0] ) continue;
// dup? can happen with arrays. parent of string
// in object, has same name as his parent, the
// name of the array. "dupname":[{"a":"b"},{"c":"d"}]
if ( p->m_name == lastName ) continue;
// update
lastName = p->m_name;
// add it up
nameArray[numNames++] = p->m_name;
// breach?
if ( numNames < 15 ) continue;
log("build: too many names in json tag");
break;
}
// assemble the names in reverse order which is correct order
for ( int32_t i = 1 ; i <= numNames ; i++ ) {
// copy into our safebuf
if ( ! nameBuf.safeStrcpy ( nameArray[numNames-i]) )
return false;
// separate names with periods
if ( ! nameBuf.pushChar('.') ) return false;
}
// remove last period
nameBuf.removeLastChar('.');
// and null terminate
if ( ! nameBuf.nullTerm() ) return false;
// change all :'s in names to .'s since : is reserved!
char *px = nameBuf.getBufStart();
for ( ; *px ; px++ ) if ( *px == ':' ) *px = '.';
return true;
