C# Class NGettext.PluralCompile.Compiler.PluralRuleCompiler

Compiler that compiles a plural rule abstract syntax tree into a managed dynamic method delegate using an IL code generator.

Public Methods

Method	Description
CompileToDynamicMethod ( Token astRoot, Type outputDelegateType ) : Delegate	Compiles a plural rule abstract syntax tree into managed dynamic method delegate using an IL code generator.

Method	Description
CompileFinish ( ILGenerator il ) : void	Emits instructions required for compilation stop procedure.
CompileNode ( ILGenerator il, Token node ) : void	Recursively compiles an AST node to the IL instructions.
CompileStart ( ILGenerator il ) : void	Emits instructions required for compilation start procedure.
CreateDynamicMethod ( Type outputDelegateType ) : DynamicMethod	Creates a new DynamicMethod instance with signature of given delegate type.
EmitConditionalBranch ( ILGenerator il, OpCode conditionOpCode, Token trueNode, Token falseNode ) : void	Emits instructions required for conditional branch using given OpCode to check condition and given nodes for positive and negative branches.
EmitConditionalValue ( ILGenerator il, OpCode conditionOpCode, long trueValue = 1, long falseValue ) : void	Emits instructions required for creating a value on the stack based on specified condition operation result. We can not use simplified OpCodes.Clt, OpCodes.Cgt and similar instructions because we use an Int64 as an argument value.

Emits instructions required for compilation stop procedure.

protected CompileFinish ( ILGenerator il ) : void
il	System.Reflection.Emit.ILGenerator	IL generator instance.
return	void

Recursively compiles an AST node to the IL instructions.

protected CompileNode ( ILGenerator il, Token node ) : void
il	System.Reflection.Emit.ILGenerator	IL generator instance.
node	NGettext.Plural.Ast.Token	AST node.
return	void

Emits instructions required for compilation start procedure.

protected CompileStart ( ILGenerator il ) : void
il	System.Reflection.Emit.ILGenerator	IL generator instance.
return	void

Compiles a plural rule abstract syntax tree into managed dynamic method delegate using an IL code generator.

public CompileToDynamicMethod ( Token astRoot, Type outputDelegateType ) : Delegate
astRoot	NGettext.Plural.Ast.Token	abstract syntax tree root node.
outputDelegateType	System.Type	Type of output delegate.
return	System.Delegate

Creates a new DynamicMethod instance with signature of given delegate type.

protected CreateDynamicMethod ( Type outputDelegateType ) : DynamicMethod
outputDelegateType	System.Type
return	System.Reflection.Emit.DynamicMethod

Emits instructions required for conditional branch using given OpCode to check condition and given nodes for positive and negative branches.

protected EmitConditionalBranch ( ILGenerator il, OpCode conditionOpCode, Token trueNode, Token falseNode ) : void
il	System.Reflection.Emit.ILGenerator	IL generator instance.
conditionOpCode	System.Reflection.Emit.OpCode	OpCode of the condition check operation.
trueNode	NGettext.Plural.Ast.Token	AST node that will be executed when condition returns positive result.
falseNode	NGettext.Plural.Ast.Token	AST node that will be executed when condition returns negative result.
return	void

Emits instructions required for creating a value on the stack based on specified condition operation result.

We can not use simplified OpCodes.Clt, OpCodes.Cgt and similar instructions because we use an Int64 as an argument value.

protected EmitConditionalValue ( ILGenerator il, OpCode conditionOpCode, long trueValue = 1, long falseValue ) : void
il	System.Reflection.Emit.ILGenerator	IL generator instance.
conditionOpCode	System.Reflection.Emit.OpCode	OpCode of the condition check operation.
trueValue	long	A value that will be put on stack when condition returns positive result.
falseValue	long	A value that will be put on stack when condition returns negative result.
return	void
