Method Details
-
getSourceName
Returns the URI, path or descriptive text indicating the origin of this script's source code. -
setSourceName
Sets the URI, path or descriptive text indicating the origin of this script's source code. -
getEncodedSourceStart
public int getEncodedSourceStart()Returns the start offset of the encoded source. Only valid ifgetEncodedSource()
returns non-null
. -
setEncodedSourceStart
public void setEncodedSourceStart(int start) Used by code generator.- See Also:
-
getEncodedSourceEnd
public int getEncodedSourceEnd()Returns the end offset of the encoded source. Only valid ifgetEncodedSource()
returns non-null
. -
setEncodedSourceEnd
public void setEncodedSourceEnd(int end) Used by code generator.- See Also:
-
setEncodedSourceBounds
public void setEncodedSourceBounds(int start, int end) Used by code generator.- See Also:
-
setEncodedSource
Used by the code generator.- See Also:
-
getEncodedSource
Returns a canonical version of the source for this script or function, for use in implementing theObject.toSource
method of JavaScript objects. This source encoding is only recorded during code generation. It must be passed back toDecompiler.decompile(java.lang.String, int, org.mozilla.javascript.UintMap)
to construct the human-readable source string.Given a parsed AST, you can always convert it to source code using the
AstNode.toSource(int)
method, although it's not guaranteed to produce exactly the same results asObject.toSource
with respect to formatting, parenthesization and other details.- Returns:
- the encoded source, or
null
if it was not recorded.
-
getBaseLineno
public int getBaseLineno() -
setBaseLineno
public void setBaseLineno(int lineno) Sets base (starting) line number for this script or function. This is a one-time operation, and throws an exception if the line number has already been set. -
getEndLineno
public int getEndLineno() -
setEndLineno
public void setEndLineno(int lineno) -
getFunctionCount
public int getFunctionCount() -
getFunctionNode

getFunctions

addFunction
Adds aFunctionNode
to the functions table for codegen. Does not set the parent of the node.- Returns:
- the index of the function within its parent

flattenSymbolTable
public void flattenSymbolTable(boolean flattenAllTables) Assign every symbol a unique integer index. Generate arrays of variable names and constness that can be indexed by those indices.- Parameters:
flattenAllTables
- if true, flatten all symbol tables, included nested block scope symbol tables. If false, just flatten the script's or function's symbol table.
