Represents information about one or more code generation optimizations.

Méthodes publiques

Méthode	Description
EmitLongJump ( ILGenerator generator, ILLabel targetLabel ) : void	Emits code to branch between statements, even if code generation is within a finally block (where unconditional branches are not allowed).
GetBreakTarget ( string labelName = null ) : ILLabel	Returns the break target for the statement with the given label, if one is provided, or the top-most break target otherwise.
GetContinueTarget ( string labelName = null ) : ILLabel	Returns the continue target for the statement with the given label, if one is provided, or the top-most continue target otherwise.
GetRegExpVariable ( ILGenerator generator, Jurassic.Compiler.RegularExpressionLiteral literal ) : ILLocalVariable	Retrieves a variable that can be used to store a shared instance of a regular expression.
MarkSequencePoint ( ILGenerator generator, Jurassic.Compiler.SourceCodeSpan span ) : void	Emits a sequence point, and sets the SourceSpan property.
OptimizationInfo ( ScriptEngine engine ) : System	Creates a new OptimizationInfo instance.
PopBreakOrContinueInfo ( ) : void	Removes the top-most break or continue information from the stack.
PushBreakOrContinueInfo ( IList labelNames, ILLabel breakTarget, ILLabel continueTarget, bool labelledOnly ) : void	Pushes information about break or continue targets to a stack.

Méthode	Description
GetBreakOrContinueLabelDepth ( ILLabel label ) : int	Searches for the given label in the break/continue stack.

Emits code to branch between statements, even if code generation is within a finally block (where unconditional branches are not allowed).

public EmitLongJump ( ILGenerator generator, ILLabel targetLabel ) : void
generator	ILGenerator	The generator to output the CIL to.
targetLabel	ILLabel	The label to jump to.
Résultat	void

Returns the break target for the statement with the given label, if one is provided, or the top-most break target otherwise.

public GetBreakTarget ( string labelName = null ) : ILLabel
labelName	string	The label associated with the break target. Can be /// null.
Résultat	ILLabel

Returns the continue target for the statement with the given label, if one is provided, or the top-most continue target otherwise.

public GetContinueTarget ( string labelName = null ) : ILLabel
labelName	string	The label associated with the continue target. Can be /// null.
Résultat	ILLabel

Retrieves a variable that can be used to store a shared instance of a regular expression.

public GetRegExpVariable ( ILGenerator generator, Jurassic.Compiler.RegularExpressionLiteral literal ) : ILLocalVariable
generator	ILGenerator	The IL generator used to create the variable.
literal	Jurassic.Compiler.RegularExpressionLiteral	The regular expression literal.
Résultat	ILLocalVariable

Emits a sequence point, and sets the SourceSpan property.

public MarkSequencePoint ( ILGenerator generator, Jurassic.Compiler.SourceCodeSpan span ) : void
generator	ILGenerator	The IL generator used to emit the sequence point.
span	Jurassic.Compiler.SourceCodeSpan	The source code span.
Résultat	void

Creates a new OptimizationInfo instance.

public OptimizationInfo ( ScriptEngine engine ) : System
engine	ScriptEngine	The associated script engine.
Résultat	System

Removes the top-most break or continue information from the stack.

public PopBreakOrContinueInfo ( ) : void
Résultat	void

Pushes information about break or continue targets to a stack.

public PushBreakOrContinueInfo ( IList labelNames, ILLabel breakTarget, ILLabel continueTarget, bool labelledOnly ) : void
labelNames	IList	The label names associated with the break or continue target. /// Can be null.
breakTarget	ILLabel	The IL label to jump to if a break statement is encountered.
continueTarget	ILLabel	The IL label to jump to if a continue statement is /// encountered. Can be null.
labelledOnly	bool	true if break or continue statements without a label /// should ignore this entry; false otherwise.
Résultat	void
