Description copied from interface: ScriptCompiler

Begin compilation for a script, preparing all necessary context and code to support this script's compiled representation.

Specified by:

startScript in interface ScriptCompiler

endScript

public void endScript(boolean generateLoad,
                      boolean generateMain)

Description copied from interface: ScriptCompiler

End compilation for the current script, closing all context and structures used for the compilation.

Specified by:

endScript in interface ScriptCompiler

buildStaticScopeNames

startMethod

public BodyCompiler startMethod(java.lang.String rubyName,
                                java.lang.String javaName,
                                CompilerCallback args,

                                ASTInspector inspector)

Description copied from interface: ScriptCompiler

Begin compilation for a method that has the specified number of local variables. The returned value is a token that can be used to end the method later.

Specified by:

startMethod in interface ScriptCompiler

javaName - The outward user-readable name of the method. A unique name will be generated based on this.

Returns:

An Object that represents the method within this compiler. Used in calls to endMethod once compilation for this method is completed.

startFileMethod

public BodyCompiler startFileMethod(CompilerCallback args,
                                    StaticScope scope,
                                    ASTInspector inspector)

Description copied from interface: ScriptCompiler

Begin compilation for the root of a script named __file__.

Specified by:

startFileMethod in interface ScriptCompiler

Parameters:

args - Arguments to the script, as passed via jitted wrappers

scope - The StaticScope for the script

inspector - The ASTInspector for the nodes for the script

Returns:

A new BodyCompiler for the body of the script

Description copied from interface: ScriptCompiler

Begin compilation for a the root of a script. This differs from method compilation in that it doesn't do specific-arity logic, nor does it require argument processing.

Specified by:

startRoot in interface ScriptCompiler

javaName - The outward user-readable name of the method. A unique name will be generated based on this.

Returns:

An Object that represents the method within this compiler. Used in calls to endMethod once compilation for this method is completed.
