org.codehaus.groovy.classgen.BytecodeSequence

All Implemented Interfaces:

NodeMetaDataHandler

public class BytecodeSequence
extends Statement

This class represents a sequence of BytecodeInstructions or ASTNodes. The evaluation is depending on the type of the visitor.

Constructor Details

BytecodeSequence

public BytecodeSequence(BytecodeInstruction instruction)

BytecodeSequence

public BytecodeSequence(List<?> instructions)

Method Details

getInstructions

public List<?> getInstructions()

getBytecodeInstruction

public BytecodeInstruction getBytecodeInstruction()

Returns the singular BytecodeInstruction.

Returns:

null if instruction(s) is not a BytecodeInstruction

visit

public void visit(GroovyCodeVisitor visitor)

Delegates to the visit method used for this class. If the visitor is a ClassGenerator, then ClassGenerator.visitBytecodeSequence(BytecodeSequence) is called with this instance. If the visitor is no ClassGenerator, then this method will call visit on each ASTNode element sorted by this class. If one element is a BytecodeInstruction, then it will be skipped as it is no ASTNode.

Overrides:

visit in class ASTNode
