Detailed Description

Definition of a field domain.

A field domain is a set of constraints that apply to one or several fields.

This is a concept found in File Geodatabase or GeoPackage (using the schema extension) for example.

A field domain can be:

• OGRCodedFieldDomain: an enumerated list of (code, value) tuples.
• OGRRangeFieldDomain: a range constraint (min, max).
• OGRGlobFieldDomain: a glob expression.

Constructor & Destructor Documentation

~OGRFieldDomain()

OGRFieldDomain::~OGRFieldDomain ( )

pure virtualdefault

Destructor.

This is the same as the C function OGR_FldDomain_Destroy().

Member Function Documentation

Clone()

virtual OGRFieldDomain* OGRFieldDomain::Clone ( ) const

pure virtual

Clone.

Return a cloned object, or nullptr in case of error.

Implemented in OGRGlobFieldDomain, OGRRangeFieldDomain, and OGRCodedFieldDomain.

GetDescription()

const std::string& OGRFieldDomain::GetDescription ( ) const

inline

Get the description of the field domain.

Empty string if there is none.

This is the same as the C function OGR_FldDomain_GetDescription().

GetDomainType()

OGRFieldDomainType OGRFieldDomain::GetDomainType ( ) const

inline

Get the type of the field domain.

This is the same as the C function OGR_FldDomain_GetDomainType().

GetFieldSubType()

OGRFieldSubType OGRFieldDomain::GetFieldSubType ( ) const

inline

Get the field subtype.

This is the same as the C function OGR_FldDomain_GetFieldSubType().

GetFieldType()

OGRFieldType OGRFieldDomain::GetFieldType ( ) const

inline

Get the field type.

This is the same as the C function OGR_FldDomain_GetFieldType().

GetMergePolicy()

OGRFieldDomainMergePolicy OGRFieldDomain::GetMergePolicy ( ) const

inline

Get the merge policy.

This is the same as the C function OGR_FldDomain_GetMergePolicy().

GetName()

const std::string& OGRFieldDomain::GetName ( ) const

inline

Get the name of the field domain.

This is the same as the C function OGR_FldDomain_GetName().

GetSplitPolicy()

OGRFieldDomainSplitPolicy OGRFieldDomain::GetSplitPolicy ( ) const

inline

Get the split policy.

This is the same as the C function OGR_FldDomain_GetSplitPolicy().

SetMergePolicy()

void OGRFieldDomain::SetMergePolicy ( OGRFieldDomainMergePolicy  policy )

inline

Set the merge policy.

This is the same as the C function OGR_FldDomain_SetMergePolicy().

SetSplitPolicy()

void OGRFieldDomain::SetSplitPolicy ( OGRFieldDomainSplitPolicy  policy )

inline

Set the split policy.

This is the same as the C function OGR_FldDomain_SetSplitPolicy().
