{ANY}
  • valid_session (session: EDC_SESSION): BOOLEAN
    Check that the session has enough rights for what the query wants to do (e.g. session.in_transaction for updates, and so on)
{}
{ANY}
  • is_equal (other: EDC_QUERY_OPTION_FOR_UPDATE): BOOLEAN
    Is other attached to an object considered equal to current object?

effective function
{ANY}

Is other attached to an object considered equal to current object?
require
  • other /= Void
ensure
  • commutative: generating_type = other.generating_type implies Result = other.is_equal(Current)
is_real_singleton: BOOLEAN
effective function
{}

ensure
  • assertion_check_only: Result
singleton_memory_pool: HASHED_DICTIONARY[POINTER, STRING]
once function

This pool is unique in the whole system.
A memory is kept for each singleton type (type, not class) in the system.

effective function
{}
