analyseCode

public FlowInfo analyseCode(BlockScope currentScope,
                            FlowContext flowContext,
                            FlowInfo flowInfo)

Specified by:

generateCodeForStringSwitch

public void generateCodeForStringSwitch(BlockScope currentScope,
                                        CodeStream codeStream)

Switch on String code generation This assumes that hashCode() specification for java.lang.String is API and is stable.

Parameters:

currentScope - org.aspectj.org.eclipse.jdt.internal.compiler.lookup.BlockScope

codeStream - org.aspectj.org.eclipse.jdt.internal.compiler.codegen.CodeStream

See Also:

"http://download.oracle.com/javase/6/docs/api/java/lang/String.html"

generateCode

public void generateCode(BlockScope currentScope,
                         CodeStream codeStream)

Switch code generation

Specified by:

generateCode in class Statement

Parameters:

currentScope - org.aspectj.org.eclipse.jdt.internal.compiler.lookup.BlockScope

codeStream - org.aspectj.org.eclipse.jdt.internal.compiler.codegen.CodeStream

printStatement

public java.lang.StringBuffer printStatement(int indent,
                                             java.lang.StringBuffer output)

Specified by:

printStatement in class Statement

resolve

public void resolve(BlockScope upperScope)

Specified by:

resolve in class Statement

traverse

public void traverse(ASTVisitor visitor,
                     BlockScope blockScope)

Overrides:

traverse in class ASTNode

branchChainTo

public void branchChainTo(BranchLabel label)

Dispatch the call on its last statement.

Overrides:

branchChainTo in class Statement

doesNotCompleteNormally

public boolean doesNotCompleteNormally()

Description copied from class: Statement

Lambda shape analysis: *Assuming* this is reachable, analyze if this completes normally i.e control flow can reach the textually next statement. For blocks, we don't perform intra-reachability analysis. We assume the lambda body is free of intrinsic control flow errors (if such errors exist they will not be flagged by this analysis, but are guaranteed to surface later on.)

Overrides:

doesNotCompleteNormally in class Statement

See Also:

Block.doesNotCompleteNormally()

completesByContinue

public boolean completesByContinue()

Description copied from class: Statement

Lambda shape analysis: *Assuming* this is reachable, analyze if this completes by continuing i.e control flow cannot reach the textually next statement. This is necessitated by the fact that continue claims to not complete normally. So this is necessary to discriminate between do { continue; } while (false); which completes normally and do { throw new Exception(); } while (false); which does not complete normally.

Overrides:

completesByContinue in class Statement
