Method Detail

newAnnotation

public AnnotationDescrBuilder<RuleDescrBuilder> newAnnotation(java.lang.String name)

Specified by:

newAnnotation in interface AnnotatedDescrBuilder<RuleDescrBuilder>

attribute

public AttributeDescrBuilder<RuleDescrBuilder> attribute(java.lang.String name)

Description copied from interface: AttributeSupportBuilder

Adds a new attribute to the statement

Specified by:

attribute in interface AttributeSupportBuilder<RuleDescrBuilder>

Parameters:

name - the attribute name

Returns:

the AttributeDescrBuilder to set the attribute value

name

public RuleDescrBuilder name(java.lang.String name)

Description copied from interface: RuleDescrBuilder

The name of the rule. Best practice is to keep rule names relatively short, i.e. under 60 characters.

Specified by:

name in interface RuleDescrBuilder

Parameters:

name - name of the rule

Returns:

itself

extendsRule

public RuleDescrBuilder extendsRule(java.lang.String name)

Description copied from interface: RuleDescrBuilder

Defines the name of the rule this rule extends. It will cause the rule to inherit the LHS from the parent rule.

Specified by:

extendsRule in interface RuleDescrBuilder

Parameters:

name - name of the parent rule

Returns:

itself

rhs

public RuleDescrBuilder rhs(java.lang.String rhs)

Description copied from interface: RuleDescrBuilder

The default right hand side (consequence) of the rule. This is a code block that must be valid according to the used dialect (java or MVEL). In particular, the deprecated '#' character, that was used for one line comments is not supported. For one line comments, please use standard '//'.

Specified by:

rhs in interface RuleDescrBuilder

Parameters:

rhs - the code block

Returns:

itself

namedRhs

public RuleDescrBuilder namedRhs(java.lang.String name,
                                 java.lang.String rhs)
