def create_for_statement(cls, statement_container, compiler, **kw):

overrides sqlalchemy.sql.base.CompileState.create_for_statement

overridden in sqlalchemy.orm.context.ORMFromStatementCompileState, sqlalchemy.orm.context.ORMSelectCompileState

Create a context for a statement given a .Compiler.

This method is always invoked in the context of SQLCompiler.process().

For a Select object, this would be invoked from SQLCompiler.visit_select(). For the special FromStatement object used by Query to indicate "Query.from_statement()", this is called by FromStatement._compiler_dispatch() that would be called by SQLCompiler.process().
