Constructor Detail

AbstractSchemaParser

protected AbstractSchemaParser(java.lang.Class<T> schemaObjectType,
                               I18n errorCodeOnNull,
                               I18n errorCodeOnParseExceptionWithPosition,
                               I18n errorCodeOnParseException)

Instantiates a new abstract schema parser.

Parameters:

errorCodeOnNull - error code used when schema element is null

errorCodeOnParseExceptionWithPosition - error code used on parse error when position is known

errorCodeOnParseException - error code used on parse error when position is unknown

Method Detail

reset

protected void reset(java.lang.String spec)

Initializes the plumbing by creating a pipe and coupling the parser/lexer pair with it. param spec the specification to be parsed

Parameters:

spec - the spec

setParserMonitor

public void setParserMonitor(ParserMonitor parserMonitor)

Sets the parser monitor.

Parameters:

parserMonitor - the new parser monitor

setQuirksMode

public void setQuirksMode(boolean enabled)

Sets the quirks mode. If enabled the parser accepts non-numeric OIDs and some special characters in descriptions.

Parameters:

enabled - the new quirks mode

isQuirksMode

public boolean isQuirksMode()

Checks if quirks mode is enabled.

Returns:

true, if is quirks mode is enabled

parse

Parameters:

schemaDescription - The SchemaObject description

Returns:

A SchemaObject instance

Throws:

java.text.ParseException - If the parsing failed

wrapRecognitionException

private java.text.ParseException wrapRecognitionException(java.lang.String schemaDescription,
