## ◆ GetInteger()

int OGRFeature::FieldValue::GetInteger | ( |  | ) | const
| inline

Return the integer value.

Only use that method if and only if GetType() == OFTInteger.

## ◆ GetInteger64()

GIntBig OGRFeature::FieldValue::GetInteger64 | ( |  | ) | const
| inline

Return the 64-bit integer value.

Only use that method if and only if GetType() == OFTInteger64.

## ◆ GetString()

const char * OGRFeature::FieldValue::GetString | ( |  | ) | const
| inline

Return the string value.

Only use that method if and only if GetType() == OFTString.
