Interface LexicalProcessor<T>

All Known Implementing Classes:

DelegatingLexicalProcessor, DomLexicalProcessor, NullLexicalProcessor

public interface LexicalProcessor<T>

Takes care of converting between XNode tree and specific lexical representation (XML, JSON, YAML). As a special case, NullLexicalProcessor uses XNode tree itself as a lexical representation.

Method Details

read

@NotNull
@NotNull RootXNodeImpl read(@NotNull
 @NotNull ParserSource source,
 @NotNull
 @NotNull ParsingContext parsingContext)
                     throws SchemaException,
IOException

Throws:

SchemaException

IOException

readObjects

@NotNull
@NotNull List<RootXNodeImpl> readObjects(@NotNull
 @NotNull ParserSource source,
 @NotNull
 @NotNull ParsingContext parsingContext)
                                  throws SchemaException,
IOException

Throws:

SchemaException

IOException

readObjectsIteratively

void readObjectsIteratively(@NotNull
 @NotNull ParserSource source,
 @NotNull
 @NotNull ParsingContext parsingContext,
 LexicalProcessor.RootXNodeHandler handler)
                     throws SchemaException,
IOException

Throws:

SchemaException

IOException

canRead

boolean canRead(@NotNull
 @NotNull File file)
         throws IOException

Checks if the processor can read from a given file. (Guessed by file extension, for now.) Used for autodetection of language.

Throws:

IOException

canRead

boolean canRead(@NotNull
 @NotNull String dataString)

Checks if the processor can read from a given string. Note this is only an approximative information (for now). Used for autodetection of language.

write

@NotNull
T write(@NotNull
 @NotNull RootXNode xnode,
 @Nullable
 @Nullable SerializationContext serializationContext)
 throws SchemaException

Serializes a root node into XNode tree.

Throws:

SchemaException

write

@NotNull
T write(@NotNull
 @NotNull XNode xnode,
 @NotNull
 @NotNull QName rootElementName,
 @Nullable
 @Nullable SerializationContext serializationContext)
 throws SchemaException

Serializes a non-root node into XNode tree. So, xnode SHOULD NOT be a root node (at least for now). TODO consider removing - replacing by the previous form.

Throws:

SchemaException

write

@NotNull
T write(@NotNull
 @NotNull List<RootXNodeImpl> roots,
 @Nullable
 @Nullable SerializationContext context)
 throws SchemaException

TODO Not supported for NullLexicalProcessor, though.

Throws:

SchemaException
