[RFC]: Standardise Constraint Naming in Metadata Source

[simon-mundy]

Proposed Version

0.6.0

Basic Information

Provide a mechanism for a component-wide standardisation of constraint naming. Currently 'laminas' is prepended to a constraint name across multiple adapters in the \MetaData\Source. Instead we should enforce this from within PhpDb\Metadata\Source\AbstractSource and allow this to be changed at a global level if desired.

Background

_laminas_ key was hardcoded to the file.

Considerations

Not a huge impact, other than to see that it is legacy.

Proposal(s)

protected string $constraintPrefix = '';

public function setConstraintPrefix(string $prefix): void
{
    // Ensure alphanumeric and remove leading/trailing underscore
}

protected function getResolvedConstraintPrefix(): string
{
    return '_' . $this->constraintPrefix . '_';
}
