Detailed Description

A rule as persisted on disk.

Constructor & Destructor Documentation

Persisted_rule()

Persisted_rule::Persisted_rule ( rts::Cursor *  c )

inlineexplicit

Constructs a Persisted_rule object that copies all data into the current heap.

The interface is constructed this way due to on some OS'es (e.g. Windows), every shared library has its own heap.

Member Function Documentation

copy_and_set()

void Persisted_rule::copy_and_set ( Mysql::Nullable< std::string > *  property, rts::Cursor *  c, int  colno  )

inlineprivate

Reads from a Cursor and writes to a property of type Nullable<string> after forcing a copy of the string buffer.

The function calls a member function in Cursor that is located in the server's dynamic library.

set_if_present()

void Persisted_rule::set_if_present ( rts::Cursor *  cursor, rts::Cursor::column_id  column, Mysql::Nullable< std::string >  value  )

inlineprivate

Writes a string value to the cursor's column if it exists.

set_message()

void Persisted_rule::set_message ( const std::string &  message_arg )

inline

Convenience function, may be called with a const char*.

set_normalized_pattern()

void Persisted_rule::set_normalized_pattern ( const std::string &  s )

inline

Convenience function, may be called with a const char*.

set_pattern_digest()

void Persisted_rule::set_pattern_digest ( const std::string &  s )

inline

Convenience function, may be called with a const char*.

write_to()

bool Persisted_rule::write_to ( rts::Cursor *  c )

inline

Writes the values in this Persisted_rule to the table at the row pointed to by the cursor.

Values that don't have a corresponding column in the table will be ignored.

message

Mysql::Nullable<std::string> Persisted_rule::message

normalized_pattern

The normalized pattern, write-only.

pattern

Mysql::Nullable<std::string> Persisted_rule::pattern

The rewrite rule's pattern string.

pattern_db

Mysql::Nullable<std::string> Persisted_rule::pattern_db

The pattern's current database.

pattern_digest

Mysql::Nullable<std::string> Persisted_rule::pattern_digest

The pattern's digest, write-only.

replacement

Mysql::Nullable<std::string> Persisted_rule::replacement

The rewrite rule's replacement string.
