InnerClassesTableEntry

public InnerClassesTableEntry()
Creates a new instance of InnerClassesTableEntry

Method Detail

setInnerClassInfoIndex

public void setInnerClassInfoIndex(int innClassInfoIndex)
Description copied from interface: InnerClassesTableEntry
The value of the inner_class_info_index item must be zero or a valid index into the constant_pool table. The constant_pool entry at that index must be a CONSTANT_Class_info structure representing the inner class. The remaining items in the classes array entry give information about the inner class itself.

Specified by:
setInnerClassInfoIndex in interface InnerClassesTableEntry
Parameters:
innClassInfoIndex - A valid index into the constant pool table

getInnerClassInfoIndex

public int getInnerClassInfoIndex()
Description copied from interface: InnerClassesTableEntry
The value of the inner_class_info_index item must be zero or a valid index into the constant_pool table. The constant_pool entry at that index must be a CONSTANT_Class_info structure representing the inner class. The remaining items in the classes array entry give information about the inner class itself.

Specified by:
getInnerClassInfoIndex in interface InnerClassesTableEntry
Returns:
int A valid index into the constant pool table

setOuterClassInfoIndex

public void setOuterClassInfoIndex(int outClassInfoIndex)
Description copied from interface: InnerClassesTableEntry
If the inner class is not a member, the value of the outer_class_info_index item must be zero. Otherwise, the value of the outer_class_info_index item must be a valid index into the constant_pool table, and the entry at that index must be a CONSTANT_Class_info structure representing the class or interface of which the inner class is a member

Specified by:
setOuterClassInfoIndex in interface InnerClassesTableEntry
Parameters:
outClassInfoIndex - A valid index into the constant pool table

getOuterClassInfoIndex

public int getOuterClassInfoIndex()
Description copied from interface: InnerClassesTableEntry
If the inner class is not a member, the value of the outer_class_info_index item must be zero. Otherwise, the value of the outer_class_info_index item must be a valid index into the constant_pool table, and the entry at that index must be a CONSTANT_Class_info structure representing the class or interface of which the inner class is a member

Specified by:
getOuterClassInfoIndex in interface InnerClassesTableEntry
Returns:
int A valid index into the constant pool table

setInnerNameIndex

public void setInnerNameIndex(int innNameIndex)
Description copied from interface: InnerClassesTableEntry
If the inner class is anonymous, the value of the inner_name_index item must be zero. Otherwise, the value of the inner_name_index item must be a valid index into the constant_pool table, and the entry at that index must be a CONSTANT_Utf8_info structure that represents the original simple name of the inner class, as given in the source code from which this class file was compiled

Specified by:
setInnerNameIndex in interface InnerClassesTableEntry
Parameters:
innNameIndex - A valid index into the constant pool table

getInnerNameIndex

public int getInnerNameIndex()
Description copied from interface: InnerClassesTableEntry
If the inner class is anonymous, the value of the inner_name_index item must be zero. Otherwise, the value of the inner_name_index item must be a valid index into the constant_pool table, and the entry at that index must be a CONSTANT_Utf8_info structure that represents the original simple name of the inner class, as given in the source code from which this class file was compiled

Specified by:
getInnerNameIndex in interface InnerClassesTableEntry
Returns:
int A valid index into the constant pool table

setInnerClassAccesFlags

public void setInnerClassAccesFlags(int accessFlags)
Description copied from interface: InnerClassesTableEntry
The value of the inner_class_access_flags item is a mask of flags used to denote access permissions to and properties of class or interface as declared in the source code from which this class file was compiled. It is used by compilers to recover the original information when source code is not available. The flags are:
Flag Name Value Meaning
ACC_PUBLIC 0x0001 Marked or implicitly public in source.
ACC_PRIVATE 0x0002 Marked private in source.
ACC_PROTECTED 0x0004 Marked protected in source.
ACC_STATIC 0x0008 Marked or implicitly static in source.
ACC_FINAL 0x0010 Marked final in source.
ACC_INTERFACE 0x0200 Was an interface in source.
ACC_ABSTRACT 0x0400 Marked or implicitly abstract in source.

Specified by:
setInnerClassAccesFlags in interface InnerClassesTableEntry
Parameters:
accessFlags - A bit mask denoting the which access modifiers are applied to the given class

getInnerClassAccessFlags

public int getInnerClassAccessFlags()
Description copied from interface: InnerClassesTableEntry
Returns the access flags set via the setInnerClassAccessFlags method.

Specified by:
getInnerClassAccessFlags in interface InnerClassesTableEntry
Returns:

Flag Name Value Meaning
ACC_PUBLIC 0x0001 Marked or implicitly public in source.
