All Implemented Interfaces:

Analyzer

Direct Known Subclasses:

SymbolizerTypeAnalyzer

public class ParametersAnalyzer
extends AbstractAnalyzer

Basic analyzer for symbolizer nodes. We check the nature of inner SeParameter instances. We try to prove that :

• We just need one field to use the node
• All the analysis used in the node are of the same type
• None of the analysis is dependant upon another one.

Method Detail

analyzeParameters

public void analyzeParameters(SymbolizerNode sn)

Analyses the given SymbolizerNode instance. It will get its UsedAnalysis and set of needed fields so that we can determine if :

• It contains nested analysis
• It contains analysis made on different fields
• There is only one type of analysis used

Parameters:

sn -

isAnalysisUnique

public boolean isAnalysisUnique()

Returns true if and only if there is only one type of analysis referenced in the inner UsedAnalysis.

Returns:

isAnalysisLight

public boolean isAnalysisLight()

Returns true if and only if the found analysis does not contain other ones as parameter.

Returns:

isFieldUnique

public boolean isFieldUnique()

Returns true if and only if there is only one needed field for all the referenced analysis.

Returns:

getUsedAnalysis

public UsedAnalysis getUsedAnalysis()

Gets the compilation of all the analysis that have been made in the last analyzed SymbolizerNode.

Returns:

getStatus

public String getStatus()

Get a String text explaining the status of the currently analyzed SymbolizerNode.

Returns:
