addRule

public void addRule(java.lang.String expr,
                    Style style)

Adds new rule to the builder rule set. The rules are defined by a filter expression and corresponding style.
Filter expressions are defined using simple built-in SQL like language with the following properties:
- The following boolean operators are supported: AND, OR, NOT.
- The following predicates are supported: IS NULL, IS NOT NULL, =, <>, <=, >=, <, >.
- Operator precedence is similar to SQL (NOT > AND > OR), parenthesis can be used to group expressions.
- There are few prebuilt variables (view::zoom, geometry::type), other variables correspond to metadata values.

参数:

expr - The filter expression to use for this rule. For example, "geometry::type = 'linestring' AND type = 'road'"

style - The style for this rule.

addRule

public void addRule(Style style)

Adds new rule to the builder rule set. This method should be used to add the 'default' style, if no filter needs to be applied.

参数:

style - The style for this rule.

buildSelector

public StyleSelector buildSelector()

Builds a new style selector from the added rule list.

返回:

Style selector with all the added rules.
