Data::Sah::Resolve provides resolve_schema. Sah schemas can be defined in terms of other schemas as base. The resolving process follows the (outermost) base schema until it finds a builtin type as the (innermost) base. It then returns a hash result (a DefHash with v=2) containing the type as well other information like the collected clause sets and others. This routine performs the following steps: 1. Normalize the schema Unless schema_is_normalized option is true, in which case schema is assumed to be normalized already. 2. Check if the schema's type is a builtin type Currently this is done by checking if the module of the name Data::Sah::Type::<type> is loadable. If it is a builtin type then we are done. 3. Check if the schema's type is the name of another schema This is done by checking if Sah::Schema::<name> module exists and is loadable. If this is the case then we retrieve the base schema from the $schema variable in the Sah::Schema::<name> package and repeat the process while accumulating and/or merging the clause sets. 4. If schema's type is neither, we die.

Data::Sah::Resolve provides resolve_schema. Sah schemas can be defined in terms
|
|
of other schemas as base. The resolving process follows the (outermost) base
|
|
schema until it finds a builtin type as the (innermost) base. It then returns a
|
|
hash result (a DefHash with v=2) containing the type as well other information
|
|
like the collected clause sets and others.

|
|
This routine performs the following steps:
|
|
1. Normalize the schema
|
|
Unless schema_is_normalized option is true, in which case schema is assumed
|
|
to be normalized already.
|
|
2. Check if the schema's type is a builtin type
|
|
Currently this is done by checking if the module of the name
|
|
Data::Sah::Type::<type> is loadable. If it is a builtin type then we are
|
|
done.
|
|
3. Check if the schema's type is the name of another schema
|
|
This is done by checking if Sah::Schema::<name> module exists and is
|
|
loadable. If this is the case then we retrieve the base schema from the
|
|
$schema variable in the Sah::Schema::<name> package and repeat the process
|
|
while accumulating and/or merging the clause sets.
|
|
4. If schema's type is neither, we die.
