Type expressions provide tools for testing and converting different data types like strings, numbers, and boolean values. String operator expressions perform conversion operations on strings such as concatenating and converting the case. Provides mathematical operators to perform data-driven calculations within the expression framework. Special expressions that are only applicable to a single layer. Interpolate and step expressions can be used to calculate values along an interpolated curve or step function. Provides access to the property data in a feature. Type of expressionsĪn expression that defines a calculation that is processed over a set of data and can be used with the clusterProperties option of a DataSource.īoolean expressions provide a set of boolean operators expressions for evaluating boolean comparisons.Ĭolor expressions make it easier to create and manipulate color values.Ĭonditional expressions provide logic operations that are like if-statements. Expressions can be used on their own or in combination with other expressions. The Azure Maps Web SDK supports many types of expressions. The following pseudocode defines the basic structure of an expression. Each argument is either a literal value (a string, number, boolean, or null), or another expression array. The next elements (if any) are the arguments to the expression. The first element of an expression in the array is a string that specifies the name of the expression operator.
Expressions are represented as JSON arrays.
