All Implemented Interfaces:

ILcdEvaluatorFactory

Deprecated.

As this ILcdEvaluatorFactory is already used by the TLcdOGCFilterEvaluator, there is no reason for using this class directly.

@Deprecated
public class TLcdSLDFunctionEvaluatorFactory
extends Object
implements 
ILcdEvaluatorFactory

Evaluator factory for functions from SLD 1.1.0. This evaluator factory is used by TLcdOGCFilterEvaluator to support SLD specific expressions.

This evaluator factory supports the following elements:

• Recode
• Interpolate
• Categorize
• StringLength
• StringPosition
• Trim
• ChangeCase
• Concatenate
• SubString
• FormatDate
• FormatNumber
• ParameterValue

TLcdSLDFunctionEvaluatorFactory

public TLcdSLDFunctionEvaluatorFactory()

Deprecated.

Creates a new Evaluator factory.

Method Detail

canBuildEvaluator

public boolean canBuildEvaluator(ILcdGenericExpression aGenericExpression)

Deprecated.

Description copied from interface: ILcdEvaluatorFactory

Indicates whether this factory is capable of creating an evaluator for the given expression. The implementation of this method should be compatible with the implementation of populateCapabilities. If a factory can handle a given expression, this should also be clear from the filter capabilities produced by this factory.

Specified by:

canBuildEvaluator in interface ILcdEvaluatorFactory

Parameters:

aGenericExpression - the expression to build an evaluator for, if possible.

Returns:

whether or not this factory is capable of providing an ILcdEvaluator that can handle the expression given.

buildEvaluator

public ILcdEvaluator buildEvaluator(ILcdGenericExpression aGenericExpression,
                                    ILcdEvaluatorFactory aEvaluatorFactory,
                                    TLcdOGCFilterContext aContext)

Deprecated.

Description copied from interface: ILcdEvaluatorFactory

Creates an evaluator for the given expression in the given filter context. This method should only be called if canBuildEvaluator returned true.

Specified by:

buildEvaluator in interface ILcdEvaluatorFactory

Parameters:

aGenericExpression - the expression to build an evaluator for.

aEvaluatorFactory - the evaluator factory to use to build evaluators for sub-expressions, since an expression may be composed of other expressions.

aContext - the context for which to create the evaluator. The context among others contains a property retriever provider to determine how properties should be retrieved from (OGC) features.

Returns:

an evaluator that evaluates the expression.

populateCapabilities

public void populateCapabilities(TLcdOGCFilterCapabilities aFilterCapabilities)

Deprecated.

Description copied from interface: ILcdEvaluatorFactory

Populates the filter capabilities, indicating what kind of expressions can be evaluated. If an expression is supported as documented in the capabilities, the method canBuildEvaluator should return true.

Specified by:

populateCapabilities in interface ILcdEvaluatorFactory

Parameters:

aFilterCapabilities - the filter capabilities in which to declare what kind of expressions can be evaluated.
