Detailed Description

DecompilerUtil is an auxilliary class to help the decompilation, especially in flattenning a bunch of related statements. The ones that is visible from outside is flattenStmts and analyzeCondition. Everything else is internal.

Member Function Documentation

String DecompilerUtil::analyzeCondition (  Stmt   stmts[], int   code )  [inline, static]

This method basically flattenning condition statements in if, for (the second argument), while, and do...while. The problem is that Jimple cannot have complicated condition statements. So, conditions such as ((A && B) || C) is then divided into several if statements. Moreover, if statements usually followed by the nasty bad ugly goto which mess everythings up. Which at this very moment, I'm quite perplexed. Definition at line 67 of file DecompilerUtil.java.

Vector DecompilerUtil::flattenStmts (  Stmt   stmts[] )  [inline, static]

This method is basically flatten out all the related statements by replacing all occurence of Jimple's temporary variable with the real ones. This method also detects whether we find parameter bindings and field default values. Definition at line 270 of file DecompilerUtil.java.

boolean DecompilerUtil::isAbstracted (  Abstraction   lt )  [inline, static]

Returns: boolean Definition at line 479 of file DecompilerUtil.java.

boolean DecompilerUtil::isAllowField (    )  [inline, static]

Returns: boolean Definition at line 498 of file DecompilerUtil.java. Referenced by flattenStmts().

boolean DecompilerUtil::isDebugInfo (    )  [inline, static]

Returns: boolean Definition at line 509 of file DecompilerUtil.java.

void DecompilerUtil::setAllowField (  boolean   newAllowField )  [inline, static]

Parameters: newAllowField   boolean Definition at line 574 of file DecompilerUtil.java.

void DecompilerUtil::setDebugInfo (  boolean   newDebugInfo )  [inline, static]

Parameters: newDebugInfo   boolean Definition at line 581 of file DecompilerUtil.java.
