java.lang.Object

proguard.classfile.util.ArrayInitializationMatcher

public class ArrayInitializationMatcher
extends Object

This class finds sequences of instructions that correspond to primitive array initializations. Such initializations may be represented more efficiently in other bytecode languages.

ArrayInitializationMatcher

public ArrayInitializationMatcher()

Creates a new ArrayInitializationMatcher.

ArrayInitializationMatcher

public ArrayInitializationMatcher(PartialEvaluator partialEvaluator)

Creates a new ArrayInitializationMatcher that will use the given partial evaluator. The evaluator must have been initialized before trying to match any array initializations.

参数:

partialEvaluator - the evaluator to be used for the analysis.

方法详细资料

matchesArrayInitialization

public boolean matchesArrayInitialization(Clazz clazz,
 Method method,
 CodeAttribute codeAttribute,
 int newArrayOffset,
 SimpleInstruction newArrayInstruction)

Returns whether the code fragment starting at the specified newarray instruction is followed by a static array initialization.

参数:

clazz - the class.

method - the method.

codeAttribute - the code attribute.

newArrayOffset - the offset of the newarray instruction.

newArrayInstruction - the newarray instruction.

返回:

whether there is a static array initialization.

arrayInitializationStart

public int arrayInitializationStart()

Returns the first offset of the recent static array initialization, i.e. the first initialization instruction after the newarray.

arrayInitializationEnd

public int arrayInitializationEnd()

Returns the last offset of the recent static array initialization.
