toExplicitFilter

public static Filter toExplicitFilter(java.lang.String styleExpression,
                                      FeatureType featureType,
                                      java.lang.String attributeTypeName)
                               throws IllegalFilterException

Creates a filter with each value explicitly defined.

Examples:
"LIB" --> [PARTY = LIB]
"LIB, NDP" --> [[PARTY = LIB] OR [PARTY = NDP]]

Parameters:

styleExpression - the list of attribute values, separated by commas (and optional spaces)

Returns:

a filter

Throws:

IllegalFilterException

                                      Expression attribExpr)
                               throws IllegalFilterException

Creates a filter with each value explicitly defined.

Examples:
"LIB" --> [PARTY = LIB]
"LIB, NDP" --> [[PARTY = LIB] OR [PARTY = NDP]]

Parameters:

styleExpression - the list of attribute values, separated by commas (and optional spaces)

attribExpr - an Expression to compare each value with (simple case = attributeExpression)

Returns:

a filter

Throws:

IllegalFilterException

toFilter
