TSLAttributeValueOperation Class Reference

Inheritance diagram for TSLAttributeValueOperation:

Detailed Description

The base class for a MapLink classification operation, for use with TSLFeatureClassConfig and TSLFeatureClassifierGraduated classes. It is a virtual base class, and so cannot be used directly.

Its implementation relies on the following derived classes:

• TSLAttributeValueOperationAnd: Takes two operations and performs a logical AND between their results.
• TSLAttributeValueOperationElse: Provides the default case should the other operations fail.
• TSLAttributeValueOperationOr: Takes two operations and performs a logical OR between their results .
• TSLAttributeValueOperationNot: Takes two operations and performs a logical NOT between their results.
• TSLAttributeValueOperationEqualTo: Is the given attribute value the same as the operation value.
• TSLAttributeValueOperationLessThan: Is the given attribute value less than the operation value.
• TSLAttributeValueOperationGreaterThan: Is the given attribute value greater than the operation value.
• TSLAttributeValueOperationLessThanOrEqualTo: Is the given attribute value less than or equal to the operation value.
• TSLAttributeValueOperationGreaterThan: Is the given attribute value greater than or equal to the operation value.

featureName()

const char * TSLAttributeValueOperation::featureName

(

)

const

Query the feature name for this operation.

If no feature name was specified when the operation was constructed this will return an automatically generated name, based on the type of operation and the value specified.

Returns

The feature name.
