Method Summary

Modifier and Type	Method	Description
void	chkLOC()	Calls JFlexJointLexer.phLOC() if the yystate is not COMMENT or SCOMMENT.
protected abstract int	COMMENT()	Subclasses must override to get the constant value created by JFlex to represent COMMENT.
protected boolean	notInTemplateOrSubstitutionDoesNotEnd(String capture)	Determine if template substitution should end based on the first character of capture, and also recognizing tokens that increase the nesting level alternatively.
protected void	pushData()
void	reset()	Resets the instance to an initial state.
protected abstract int	SCOMMENT()	Subclasses must override to get the constant value created by JFlex to represent SCOMMENT.
protected void	substitutionOp()	Resets the substitution brace counter to 1.

public JavaScriptLexer()

Method Details

reset

public void reset()

Resets the instance to an initial state.

Specified by:

reset in interface Resettable

Overrides:

reset in class JFlexStateStacker

chkLOC

public void chkLOC()

Calls JFlexJointLexer.phLOC() if the yystate is not COMMENT or SCOMMENT.

substitutionOp

protected void substitutionOp()

Resets the substitution brace counter to 1.

notInTemplateOrSubstitutionDoesNotEnd

protected boolean notInTemplateOrSubstitutionDoesNotEnd(String capture)
                                                 throws IOException

Determine if template substitution should end based on the first character of capture, and also recognizing tokens that increase the nesting level alternatively.

Calling this method has side effects to possibly modify nEndBrace.

Returns:

true if the substitution state does not end

Throws:

IOException

pushData

protected void pushData()

COMMENT

protected abstract int COMMENT()

Subclasses must override to get the constant value created by JFlex to represent COMMENT.

SCOMMENT

protected abstract int SCOMMENT()

Subclasses must override to get the constant value created by JFlex to represent SCOMMENT.
