Package com.luciad.datamodel.expression Description

This package provides an API to evaluate expressions on data objects. An ALcdDataObjectExpressionLanguage defines the syntax and semantics of an expression language. It is capable of parsing a string (that is formatted according to its syntax) into an ILcdDataObjectExpression. Such an expression can then be evaluated on a data object to produce a value.

TLcdDataObjectExpressionLanguage provides a concrete implementation of a simple expression language. This class defines a language that allows the use of property paths and user-defined functions.

A concrete use case of these expressions can be found in TLcdGXYDataObjectLabelPainter.
