resolution

public int resolution

The resolution state of the module. Must be one of RESOLUTION_WARN_DEPRECATED, RESOLUTION_WARN_DEPRECATED_FOR_REMOVAL, and RESOLUTION_WARN_INCUBATING.

构造器详细资料

ModuleResolutionAttribute

public ModuleResolutionAttribute(int resolution)

Constructs a new ModuleResolutionAttribute.

参数:

resolution - the resolution state of the module. Must be one of RESOLUTION_WARN_DEPRECATED, RESOLUTION_WARN_DEPRECATED_FOR_REMOVAL, and RESOLUTION_WARN_INCUBATING.

ModuleResolutionAttribute

public ModuleResolutionAttribute()

Constructs an empty ModuleResolutionAttribute. This object can be passed as a prototype to the ClassReader.accept(ClassVisitor, Attribute[], int) method.

方法详细资料

read

protected Attribute read(ClassReader classReader,
 int offset,
 int length,
 char[] charBuffer,
 int codeOffset,
 Label[] labels)

从类复制的说明: Attribute

Reads a Attribute.type attribute. This method must return a new Attribute object, of type Attribute.type, corresponding to the 'length' bytes starting at 'offset', in the given ClassReader.

覆盖:

read 在类中 Attribute

参数:

classReader - the class that contains the attribute to be read.

offset - index of the first byte of the attribute's content in ClassReader. The 6 attribute header bytes (attribute_name_index and attribute_length) are not taken into account here.

length - the length of the attribute's content (excluding the 6 attribute header bytes).

charBuffer - the buffer to be used to call the ClassReader methods requiring a 'charBuffer' parameter.

codeOffset - index of the first byte of content of the enclosing Code attribute in ClassReader, or -1 if the attribute to be read is not a Code attribute. The 6 attribute header bytes (attribute_name_index and attribute_length) are not taken into account here.

labels - the labels of the method's code, or null if the attribute to be read is not a Code attribute.

返回:

a new Attribute object corresponding to the specified bytes.

write

protected ByteVector write(ClassWriter classWriter,
 byte[] code,
 int codeLength,
 int maxStack,
 int maxLocals)

从类复制的说明: Attribute

Returns the byte array form of the content of this attribute. The 6 header bytes (attribute_name_index and attribute_length) must not be added in the returned ByteVector.

覆盖:

write 在类中 Attribute

参数:

classWriter - the class to which this attribute must be added. This parameter can be used to add the items that corresponds to this attribute to the constant pool of this class.

code - the bytecode of the method corresponding to this Code attribute, or null if this attribute is not a Code attribute. Corresponds to the 'code' field of the Code attribute.

codeLength - the length of the bytecode of the method corresponding to this code attribute, or 0 if this attribute is not a Code attribute. Corresponds to the 'code_length' field of the Code attribute.

maxStack - the maximum stack size of the method corresponding to this Code attribute, or -1 if this attribute is not a Code attribute.

maxLocals - the maximum number of local variables of the method corresponding to this code attribute, or -1 if this attribute is not a Code attribute.

返回:

the byte array form of this attribute.
