Method Detail

action_tableback to summary
public short[][] action_table()

Implements abstract com.sun.java_cup.internal.runtime.lr_parser.action_table.

Access to parse-action table.

addErrorback to summary
public final void addError(ErrorMsg error)
createStepPatternback to summary
public StepPattern createStepPattern(int axis, Object test, List<Predicate> predicates)

This method is similar to findNodeType(int, Object) except that it creates a StepPattern instead of just returning a node type. It also differs in the way it handles "{uri}:*" and "{uri}:@*". The last two patterns are expanded as "*[namespace-uri() = 'uri']" and "@*[namespace-uri() = 'uri']", respectively. This expansion considerably simplifies the grouping of patterns in the Mode class. For this expansion to be correct, the priority of the pattern/template must be set to -0.25 (when no other predicates are present).

do_actionback to summary
public Symbol do_action(int act_num, lr_parser parser, Stack<Symbol> stack, int top) throws Exception

Implements abstract com.sun.java_cup.internal.runtime.lr_parser.do_action.

insertStepback to summary
public RelativeLocationPath insertStep(Step step, RelativeLocationPath rlp)
isElementAxisback to summary
public boolean isElementAxis(int axis)

Returns true if the axis applies to elements only. The axes child, attribute, namespace, descendant result in non-empty nodesets only if the context node is of type element.

Lookup a variable or parameter in the symbol table given its name.

Parameters
name:QName

Name of the symbol being looked up.

parseback to summary
public Symbol parse(String expression, int lineNumber) throws Exception

Parse the expression passed to the current scanner. If this expression contains references to local variables and it will be compiled in an external module (not in the main class) request the current template to create a new variable stack frame.

Parameters
expression:String

the expression to be parsed

lineNumber:int

Line where the current expression is defined.

production_tableback to summary
public short[][] production_table()

Implements abstract com.sun.java_cup.internal.runtime.lr_parser.production_table.

public void report_error(String message, Object info)

Overrides com.sun.java_cup.internal.runtime.lr_parser.report_error.

Doc from com.sun.java_cup.internal.runtime.lr_parser.report_error.

Report a non fatal error (or warning). This method takes a message string and an additional object (to be used by specializations implemented in subclasses). Here in the base class a very simple implementation is provided which simply prints the message to System.err.

report_fatal_errorback to summary
public void report_fatal_error(String message, Object info)

Overrides com.sun.java_cup.internal.runtime.lr_parser.report_fatal_error.

Doc from com.sun.java_cup.internal.runtime.lr_parser.report_fatal_error.

Report a fatal error. This method takes a message string and an additional object (to be used by specializations implemented in subclasses). Here in the base class a very simple implementation is provided which reports the error then throws an exception.
