Uses of Label in org.mvel2.asm

Fields in org.mvel2.asm declared as Label

Modifier and Type	Field	Description
private Label	MethodWriter.currentBasicBlock	The current basic block, i.e.
(package private) Label[]	Context.currentLocalVariableAnnotationRangeEnds	The end of each local variable range in the current local variable annotation.
(package private) Label[]	Context.currentLocalVariableAnnotationRangeStarts	The start of each local variable range in the current local variable annotation.
(package private) Label[]	Context.currentMethodLabels	The labels of the current method, indexed by bytecode offset (only bytecode offsets for which a label is needed have a non null associated Label).
(package private) static Label	Label.EMPTY_LIST	A sentinel element used to indicate the end of a list of labels.
(package private) Label	Handler.endPc	The end_pc field of this JVMS exception_table entry.
private Label	MethodWriter.firstBasicBlock	The first basic block of the method.
(package private) Label	Handler.handlerPc	The handler_pc field of this JVMS exception_table entry.
private Label	MethodWriter.lastBasicBlock	The last basic block of the method (in bytecode offset order).
(package private) Label	Label.nextBasicBlock	The successor of this label, in the order they are visited in MethodVisitor.visitLabel(org.mvel2.asm.Label).
(package private) Label	Label.nextListElement	The next element in the list of labels to which this label belongs, or null if it does not belong to any list.
(package private) Label	Frame.owner	The basic block to which these input and output stack map frames correspond.
(package private) Label	Handler.startPc	The start_pc field of this JVMS exception_table entry.
(package private) Label	Edge.successor	The successor block of this control flow graph edge.

Methods in org.mvel2.asm that return Label

Modifier and Type	Method	Description
private Label	ClassReader.createLabel(int bytecodeOffset, Label[] labels)	Creates a label without the FLAG_DEBUG_ONLY flag set, for the given bytecode offset.
(package private) Label	Label.getCanonicalInstance()	Returns the "canonical" Label instance corresponding to this label's bytecode offset, if known, otherwise the label itself.
protected Label[]	Attribute.getLabels()	Returns the labels corresponding to this attribute.
private Label	Label.pushSuccessors(Label listOfLabelsToProcess)	Adds the successors of this label in the method's control flow graph (except those corresponding to a jsr target, and those already in a list of labels) to the given list of blocks to process, and returns the new list.
protected Label	ClassReader.readLabel(int bytecodeOffset, Label[] labels)	Returns the label corresponding to the given bytecode offset.

Methods in org.mvel2.asm with parameters of type Label

Modifier and Type	Method	Description
(package private) void	Label.addSubroutineRetSuccessors(Label subroutineCaller)	Finds the basic blocks that end a subroutine starting with the basic block corresponding to this label and, for each one of them, adds an outgoing edge to the basic block following the given subroutine call.
private void	MethodWriter.addSuccessorToCurrentBasicBlock(int info, Label successor)	Adds a successor to MethodWriter.currentBasicBlock in the control flow graph.
private void	ClassReader.createDebugLabel(int bytecodeOffset, Label[] labels)	Creates a label with the FLAG_DEBUG_ONLY flag set, if there is no already existing label for the given bytecode offset (otherwise does nothing).
private Label	ClassReader.createLabel(int bytecodeOffset, Label[] labels)	Creates a label without the FLAG_DEBUG_ONLY flag set, for the given bytecode offset.
private Label	Label.pushSuccessors(Label listOfLabelsToProcess)	Adds the successors of this label in the method's control flow graph (except those corresponding to a jsr target, and those already in a list of labels) to the given list of blocks to process, and returns the new list.

private Attribute	ClassReader.readAttribute(Attribute[] attributePrototypes, java.lang.String type, int offset, int length, char[] charBuffer, int codeAttributeOffset, Label[] labels)	Reads a non standard JVMS 'attribute' structure in ClassReader.b.
protected Label	ClassReader.readLabel(int bytecodeOffset, Label[] labels)	Returns the label corresponding to the given bytecode offset.
private int	ClassReader.readVerificationTypeInfo(int verificationTypeInfoOffset, java.lang.Object[] frame, int index, char[] charBuffer, Label[] labels)	Reads a JVMS 'verification_type_info' structure and stores it at the given index in the given array.
