Method Detail

canTransform

public boolean canTransform(String feelExpression)

Description copied from interface: FeelToJuelTransformer

Test if an expression can be transformed by this transformer.

Specified by:

canTransform in interface FeelToJuelTransformer

Parameters:

feelExpression - the FEEL expression to transform

Returns:

true if the expression can be transformed by this transformer, false otherwise

transform

public String transform(FeelToJuelTransform transform,
                        String feelExpression,
                        String inputName)

Description copied from interface: FeelToJuelTransformer

Transform the FEEL expression to a JUEL expression.

Specified by:

transform in interface FeelToJuelTransformer

Parameters:

transform - the FeelToJuelTransform to use for further transforms

feelExpression - the FEEL expression to transform

inputName - the variable name of the input variable to test against

Returns:

the resulting JUEL expression
