Method Details

getExpressionParser

public static IStandardExpressionParser getExpressionParser(IEngineConfiguration configuration)

Obtain the expression parser (implementation of IStandardExpressionParser) registered by the Standard Dialect that is being currently used.

Parameters:

configuration - the configuration object for the current template execution environment.

Returns:

the parser object.

getVariableExpressionEvaluator

public static IStandardVariableExpressionEvaluator getVariableExpressionEvaluator(IEngineConfiguration configuration)

Obtain the variable expression evaluator (implementation of IStandardVariableExpressionEvaluator) registered by the Standard Dialect that is being currently used.

Normally, there should be no need to obtain this object from the developers' code (only internally from IStandardExpression implementations).

Parameters:

configuration - the configuration object for the current template execution environment.

Returns:

the variable expression evaluator object.

getConversionService

public static IStandardConversionService getConversionService(IEngineConfiguration configuration)

Obtain the conversion service (implementation of IStandardConversionService) registered by the Standard Dialect that is being currently used.

Parameters:

configuration - the configuration object for the current template execution environment.

Returns:

the conversion service object.
