This "struct" 286N/A * class is used to build content models for validation, where it 286N/A * is more efficient to fetch all of the information for each of 286N/A * these content model "fragments" than to fetch each field one at 286N/A * a time. Since configurations are allowed to have validators 286N/A * without a DTD scanner (i.e. a schema validator) and a DTD scanner 286N/A * without a validator (non-validating processor), this class can be 286N/A * used by each without requiring the presence of the other. 286N/A * When processing element declarations, the DTD scanner will build 286N/A * up a representation of the content model using the node types that 286N/A * are defined here. Since a non-validating processor only needs to 286N/A * remember the type of content model declared (i.e. ANY, EMPTY, MIXED, 286N/A * or CHILDREN), it is free to discard the specific details of the 286N/A * MIXED and CHILDREN content models described using this class. 286N/A * In the typical case of a validating processor reading the grammar 286N/A * of the document from a DTD, the information about the content model 286N/A * declared will be preserved and later "compiled" into an efficient 286N/A * form for use during element validation. Each content spec node 286N/A * that is saved is assigned a unique index that is used as a handle 286N/A * for the "value" or "otherValue" fields of other content spec nodes. 286N/A * A leaf node has a "value" that is either an index in the string 286N/A * pool of the element type of that leaf, or a value of -1 to indicate 286N/A * the special "#PCDATA" leaf type used in a mixed content model. 286N/A * For a mixed content model, the content spec will be made up of 286N/A * leaf and choice content spec nodes, with an optional "zero or more" 286N/A * node. For example, the mixed content declaration "(#PCDATA)" would 286N/A * contain a single leaf node with a node value of -1. A mixed content 286N/A * declaration of "(#PCDATA|foo)*" would have a content spec consisting 286N/A * of two leaf nodes, for the "#PCDATA" and "foo" choices, a choice node 286N/A * with the "value" set to the index of the "#PCDATA" leaf node and the 286N/A * "otherValue" set to the index of the "foo" leaf node, and a "zero or 286N/A * more" node with the "value" set to the index of the choice node. If 286N/A * the content model has more choices, for example "(#PCDATA|a|b)*", then 286N/A * there will be more corresponding choice and leaf nodes, the choice 286N/A * nodes will be chained together through the "value" field with each 286N/A * leaf node referenced by the "otherValue" field. 286N/A * For element content models, there are sequence nodes and also "zero or 286N/A * one" and "one or more" nodes. The leaf nodes would always have a valid 286N/A * string pool index, as the "#PCDATA" leaf is not used in the declarations 286N/A * for element content models. 286N/A * Name or #PCDATA. Leaf nodes that represent parsed character 286N/A * data (#PCDATA) have values of -1. 286N/A /** Represents a zero or one occurence count, '?'. */ 286N/A /** Represents a zero or more occurence count, '*'. */ 286N/A /** Represents a one or more occurence count, '+'. */ 286N/A /** Represents choice, '|'. */ 286N/A /** Represents sequence, ','. */ 286N/A * Represents any namespace specified namespace.
