Description:

ATTENTION: for protocol compatibility with JavaScriptEnvironment.
many messages are implemented with an initial underscore.
These are required as JavaScriptEnvironment catches doesNotUnderstand and
does some kludgy fiddling there.

Instance protocol:

 _argVariables

 _argVariables: aDictionary

 _localVariables

 _localVariables: aDictionary

 _outerEnvironment

 _outerEnvironment: anEnvironment

 _topEnvironment

 addLocalVariable: aVariable

 allVisibleVariables

return the variable-nodes for visible arguments and locals;
this includes outer-scope variables

 argumentCount

argumentCount

 arguments

return the value of the instance variable 'arguments' (automatically generated)

 arguments: something

set the value of the instance variable 'arguments' (automatically generated)

 functionName

return the value of the instance variable 'functionName' (automatically generated)

 functionName: something

set the value of the instance variable 'functionName' (automatically generated)

 isReturnedFrom

 isReturnedFrom: something

 lineNumber

 lineNumber: anInteger

(comment from inherited method)
set linenumber - ignored here

 localVariableNames

Modified (format): / 14-02-2019 / 11:12:33 / Claus Gittinger

 localVariables

 numArgs

 numVars

return the number of local variables.

 statements

return the value of the instance variable 'statements' (automatically generated)

 statements: aStatementNode

set the value of the instance variable 'statements' (automatically generated)

 variableValue

that is a bad kludge to fix the interpreter, which gets functionNodes as value

 xxxx_variables

 codeVariableSetupOn: codeStream for: aCompiler

generate code to set it up.

 allSubNodesDo: aBlock

evaluate aBlock for each subnode

 messageSelectorsDo: aBlock

evaluate aBlock for each message-selector sent by this node and subnodes

 messagesDo: aBlock

evaluate aBlock for each message-node sent by this node and subnodes

 variableNodesDo: aBlock

evaluate aBlock for each variable-node in this node and subnodes;
that is: all references to any variable inside the code

 value

 value: arg

 value: arg1 value: arg2

nil

 value: arg1 value: arg2 value: arg3

 value: arg1 value: arg2 value: arg3 value: arg4

 value: arg1 value: arg2 value: arg3 value: arg4 value: arg5

 value: arg1 value: arg2 value: arg3 value: arg4 value: arg5 value: arg6

 value: arg1 value: arg2 value: arg3 value: arg4 value: arg5 value: arg6 value: arg7

 value: arg1 value: arg2 value: arg3 value: arg4 value: arg5 value: arg6 value: arg7 value: arg8

 valueWithArguments: args

 valueWithReceiver: rec arguments: args

exitBlock := [:v |

 wrongNumberOfArguments: numArgsGiven

report that the number of arguments given does not match the number expected

 printOn: aStream indent: i

aStream cr.

 _isFunctionEnvironment

 _isHTMLEnvironment

 home

 isFunctionNode

 isInlineBlock

 acceptVisitor: visitor

Double dispatch back to the visitor, passing my type encoded in
the selector (visitor pattern)
