public ParseException(IParserState parserState,
 ResourceKey messageKey,
 Object... args)

Parameters:

parserState - The tokenizer in use by the parser (helpful for

 Integer lineOffset,
 Integer tokenColumn,
 Integer tokenStart,
 Integer tokenEnd,

ParseException

private ParseException(Throwable t,
 IParserState state)

Method Details

wrap

public static ParseException wrap(Throwable t,
 IParserState state)

shallowCopy

public static ParseException shallowCopy(ParseException source)

getConsoleMessage

public String getConsoleMessage()

Override so we can reset the message if need be.

Specified by:

getConsoleMessage in interface IParseIssue

Overrides:

getConsoleMessage in class ParseIssue

Returns:

the message for this parse issue formatted for printing out to a console

getExpectedType

public IType getExpectedType()

Specified by:

getExpectedType in interface IParseIssue

Overrides:

getExpectedType in class ParseIssue

Returns:

The parser's exprected types.

setExpectedType

public void setExpectedType(IType typeExpected)

Sets the expected type information from the parser.

getParamTypesExpected

public IType[] getParamTypesExpected()

setParamTypesExpected

public void setParamTypesExpected(IType... paramTypesExpected)

setParamTypesPossible

public void setParamTypesPossible(IParameterInfo[][] paramTypesPossible)

getParamTypesPossible

public IParameterInfo[][] getParamTypesPossible()

toString

public String toString()

Overrides:

toString in class Throwable

getMemberAccessContext

public IMemberAccessExpression getMemberAccessContext()

Returns:

A member access context expression to further qualify the expected type. Typically the member access expression is an LHS operand in the containing. For example, the member access expression facilitates in TypeKey qualification -- we need the name of a field/property to get an appropriately filtered TypeList for a specific TypeKey on a specific field in an entity.

setMemberAccessContext

public void setMemberAccessContext(IMemberAccessExpression ma)

Parameters:

ma - A member access expression context to further qualify the expected type.

getAlternateException

public ParseException getAlternateException()

An alternate ParseException that may provide additional information. For example, if the type of script is not know in advance (is it an expression or a program?), the script is first compiled as an expression. If a ParseException is thrown, the script is compiled as a program. If a ParseException is thrown again, the former exception is rethrown with the latter as the 'alternate'.

setAlternateException

public void setAlternateException(ParseException alternateException)

isCausedByArgumentList

public boolean isCausedByArgumentList()

setCausedByArgumentList

public void setCausedByArgumentList(boolean bCausedByArgumentList)
