Detailed Description

Schema adapter component that allows use of schemas from option parsers.

Member Function Documentation

createCopy()

OptionSchema * Parsnip::OptionSchema::createCopy ( ) const

overridevirtual

Create an identical, deep copy of the schema.

Caller is responsible for deleting it.

Implements Parsnip::SchemaBase.

dump()

std::ostream & Parsnip::OptionSchema::dump ( std::ostream &  target, int  indent, bool  suppress_indent = false  ) const

overridevirtual

Render the schema in human-friendly text.

Parameters

target	Where to write the schema.
indent	Amount of indent to use.
suppress_indent	Flag indicating indent was already performed.

Implements Parsnip::SchemaBase.

mergeSchemas()

void Parsnip::OptionSchema::mergeSchemas ( const SchemaBase &  from )

overridevirtual

Merge elements into the current schema.

Merge elements managed by this class.

• Elements seen every time are mandatory.
• Elements seen only sometime are optional.
• Elements always seen together are codependent.
• Elements must always expect similar types, except they may vary as element and list-of-same-element.

  Parameters

  from	A schema for a valid command command line.

  Exceptions

  Various

  exceptions.

Reimplemented from Parsnip::SchemaBase.

operator==()

bool Parsnip::OptionSchema::operator== ( const SchemaBase &  other ) const

overridevirtual

Check if two schemas perform the same validation.

Compare two schemas to see if they determine validity in the same manner.

Parameters

other

The schema to compare to.

Returns

True if the schemas match, false otherwise.

Reimplemented from Parsnip::SchemaBase.

validate()

void Parsnip::OptionSchema::validate ( const Parsnip::Data &  entry ) const

overridevirtual

Validate the option's schema by calling that scheme's validator.

Implements Parsnip::SchemaBase.
