getDataLayer()

const char * TSLPickResult::getDataLayer

(

)

const

Get the ID of the datalayer this result is obtained from.

The Data ID is set by the TSLDataLayer during a pick operation. This allows the data layer containing result to be identified from the result set.

The return value is a pointer to the ID of the data layer containing the result.

pickExtent()

const TSLEnvelope & TSLPickResult::pickExtent

(

)

const

New in MapLink Pro 11.2.1. Specifies the search envelope that selected the entity. When wrap-around mode is enabled, this extent might only overlap the entity if the entity "circumnavigates", i.e. the entity's location has 360 added or subtracted from its longitude.

queryType()

TSLPickResultEnum TSLPickResult::queryType

(

)

const

Queries the type enumerator - TSLPickResultEnum. This allows the user to subsequently cast the TSLPickResult to a known type. Alternatively, use the static 'isType' methods on the derived versions.
