Detailed Description

A meta-schema that determines if any, all, or exactly one or none of its subschemas are valid.

Also provides "not".

Member Function Documentation

createCopy()

ConjunctionSchema * Parsnip::ConjunctionSchema::createCopy ( ) const

overridevirtual

Create an identical, deep copy of the schema.

Caller is responsible for deleting it.

Implements Parsnip::SchemaBase.

dump()

std::ostream & Parsnip::ConjunctionSchema::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.

is_conjunction()

bool Parsnip::ConjunctionSchema::is_conjunction ( const Parsnip::Data &  schema_spec )

static

Checks a schema specification for a conjunction.

Returns

True if a conjunction is present, false otherwise.

operator==()

bool Parsnip::ConjunctionSchema::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::ConjunctionSchema::validate ( const Parsnip::Data &  entry ) const

overridevirtual

Verify that Data matches the schema.

Parameters

entry

The data to validate.

Exceptions

Various

exceptions.

Implements Parsnip::SchemaBase.
