Detailed Description

template<typename NumericType>
class Parsnip::RangeSchema< NumericType >

Schema component for numeric data, either Integer or Real.

Constructor & Destructor Documentation

RangeSchema() [1/2]

template<typename NumericType >

Parsnip::RangeSchema< NumericType >::RangeSchema	(	const NumericType	min = std::numeric_limits<NumericType>::lowest(),
		const NumericType	max = std::numeric_limits<NumericType>::max()
	)

Construct a numeric schema from a schema definition.

Template Parameters

NumericType

Either double for number or long for integer.

Parameters

min	The minimum acceptable value.
max	The maximum allowed value.

RangeSchema() [2/2]

template<typename NumericType >

Parsnip::RangeSchema< NumericType >::RangeSchema

(

const Parsnip::Data &

schema_spec

)

Construct a numeric schema from a schema definition.

Template Parameters

NumericType

Either double for number or long for integer.

Parameters

schema_spec

The schema specification.

Member Function Documentation

createCopy()

template<typename NumericType >

RangeSchema< NumericType > * Parsnip::RangeSchema< NumericType >::createCopy ( ) const

overridevirtual

Create an identical, deep copy of the schema.

Caller is responsible for deleting it.

Implements Parsnip::SchemaBase.

Reimplemented in Parsnip::IntegerSchema.

dump()

template<typename NumericType >

std::ostream & Parsnip::RangeSchema< NumericType >::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()

template<typename NumericType >

void Parsnip::RangeSchema< NumericType >::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==()

template<typename NumericType >

bool Parsnip::RangeSchema< NumericType >::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.

Reimplemented in Parsnip::IntegerSchema.

validate()

template<typename NumericType >

void Parsnip::RangeSchema< NumericType >::validate ( const Parsnip::Data &  entry ) const

overridevirtual

Validate item range: ensure the datatype falls within the allowed range.

Implements Parsnip::SchemaBase.

Reimplemented in Parsnip::IntegerSchema.
