public final class GroupPatternCategoryImpl
extends java.lang.Object

A group pattern category is a pattern category for group patterns whose child patterns are supported by the choice pattern category or choice patterns whose child patterns are such group patterns. May also contain attributes and/or text. Formally : attribute ::= attributes ::= attribute | ( attribute+ ) element ::= any oneOrMoreElement ::= element | ( element ) | ( (element* & ( element )+) ) zerorOrMoreElement ::= oneOrMoreElement | ( oneOrMoreElement ) group ::= zeroOrMoreElement | ( zeroOrMoreElement+ ) choice ::= group | ( group+ ) elementsAndText ::= choice | ( choice ) content ::= elementsAndText | ( attributes elementsAndText ) Additional constraint : an element with a given name may appear at most in one child pattern.

Method Detail

attributesPatternCategory

public AttributesPatternCategory attributesPatternCategory()

hasText

public boolean hasText()

fullPattern

public Pattern fullPattern(java.util.Map fromNameToElementDefinition)

Description copied from interface: PatternCategory

Return a pattern that meets all the entered patterns. May fail, then return null. If successfull then may use and update the given map between element name and element definition.

Specified by:

addPattern

public boolean addPattern(Name[] attributeNames,
                          boolean hasText,
                          RepeatableName[] repeatableElementNames)

Description copied from interface: PatternCategory

Add a pattern to this pattern category. The pattern is given as a text presence flag, an attribute name set and an element name sequence, where each element may or may not be repeated. Returns true in case of success or if the pattern category already includes the pattern. Returns false if the pattern is out of the pattern category but the pattern category might be affected in that case too.

Specified by:
