Field Detail

attributes

public java.util.List<Attribute> attributes

The optional attribute list.

Note that while a production's attributes are represented as an ordered list, they should be treated as a set.

dType

public java.lang.String dType

The production's declared type as a string.

type

public Type type

The production's actual type, which must be filled in after parsing a module.

name

public NonTerminal name

The name. A production's name does not have any qualification when the production is parsed. However, after uniquely renaming all productions to avoid name conflicts in the generated parser, this name may have a qualifier.

Analyzer.uniquify()

qName

public NonTerminal qName

The fully qualified name.

choice

public OrderedChoice choice

The ordered choice.

Constructor Detail

Production

public Production(java.util.List<Attribute> attributes,
                  java.lang.String dType,
                  NonTerminal name,
                  NonTerminal qName,
                  OrderedChoice choice)

Create a new production.

Parameters:

attributes - The attributes.

dType - The declared type.

name - The name.

qName - The fully qualified name.

choice - The choice.

Production

public Production(java.util.List<Attribute> attributes,
                  Type type,
                  NonTerminal name,
                  NonTerminal qName,
                  OrderedChoice choice)

Create a new production.

Parameters:

attributes - The attributes.

type - The actual type.

name - The name.

qName - The fully qualified name.

choice - The choice.

Method Detail

hashCode

public int hashCode()

Overrides:

hashCode in class java.lang.Object

isFull

public boolean isFull()

Determine whether this production is a full production.

Returns:

true if this production is full.

isPartial

public boolean isPartial()

Determine whether this production is a partial production.

Returns:

true if this production is partial.

isAddition

public boolean isAddition()

Determine whether this production is an alternative addition.

Returns:

true if this production is an alternative addition.

isRemoval

public boolean isRemoval()

Determine whether this production is an alternative removal.

Returns:

true if this production is an alternative removal.

isOverride

public boolean isOverride()

Determine whether this production is a production override.

Returns:

true if this production is a production override.

hasAttribute

public boolean hasAttribute(Attribute att)

Determine whether this production has the specified attribute.

Parameters:

att - The attribute.

Returns:

true if this production has the specified attribute.

isMemoized

public boolean isMemoized()

Determine whether this production is memoized. This method is semantically equivalent to:

 hasAttribute(Constants.ATT_MEMOIZED) ||
 ((! hasAttribute(Constants.ATT_TRANSIENT)) &&
  (! hasAttribute(Constants.ATT_INLINE)))
 

Returns:

true if this production is memoized.
