Constructor Details

DataDTOToMVELTranslator

public DataDTOToMVELTranslator()

Method Details

createMVEL

public String createMVEL(String entityKey,
 DataDTO dataDTO,
 RuleBuilderFieldService fieldService)
                  throws MVELTranslationException

Throws:

MVELTranslationException

buildMVEL

protected void buildMVEL(DataDTO dataDTO,
 StringBuffer sb,
 String entityKey,
 String groupOperator,
 RuleBuilderFieldService fieldService)
                  throws MVELTranslationException

Throws:

MVELTranslationException

buildExpression

protected void buildExpression(ExpressionDTO expressionDTO,
 StringBuffer sb,
 String entityKey,
 BLCOperator operator,
 RuleBuilderFieldService fieldService)
                        throws MVELTranslationException

Throws:

MVELTranslationException

extractBasicValues

protected Object[] extractBasicValues(Object value)

escapeStringLiteralValue

protected String escapeStringLiteralValue(String value)

Escapes a single value so that it can be placed between the double quotes of an MVEL string literal. Backslashes are escaped first, so that an escaped quote cannot be turned back into a closing quote. Since every double quote is escaped, the result never starts with a double quote, so formatValue(java.lang.String, java.lang.String, org.broadleafcommerce.common.presentation.client.SupportedFieldType, org.broadleafcommerce.common.presentation.client.SupportedFieldType, java.lang.Object[], boolean, boolean, boolean) always adds the quotes itself.

Parameters:

value - the value as entered in the rule builder

Returns:

the escaped value, without surrounding quotes

isStringLiteralType

protected boolean isStringLiteralType(org.broadleafcommerce.common.presentation.client.SupportedFieldType type,
 org.broadleafcommerce.common.presentation.client.SupportedFieldType secondaryType)

Returns:

true if formatValue(java.lang.String, java.lang.String, org.broadleafcommerce.common.presentation.client.SupportedFieldType, org.broadleafcommerce.common.presentation.client.SupportedFieldType, java.lang.Object[], boolean, boolean, boolean) writes values of the given type as quoted string literals

escapeInternalQuotes

protected String escapeInternalQuotes(String processedValue)

escapeInternalMiltyQuotes

protected String escapeInternalMiltyQuotes(String processedValue)

isProjection

public boolean isProjection(Object value)

buildCollectionExpression

 boolean ignoreCase,
 boolean isNegation,
 boolean ignoreQuotes)
                                  throws MVELTranslationException
