Field Detail

parent

protected ClassFile parent

ClassFile in which this field information is found.

access_flags

public AccessFlags access_flags

Access permissions and properties of the field.

name_index

public int name_index

The value of the name_index item must be a valid index into the constant_pool table. The constant_pool entry at that index must be a CONSTANT_Utf8_info structure which must represent a valid Java field name stored as a simple (not fully qualified) name, that is, as a Java identifier.

descriptor_index

public int descriptor_index

The value of the descriptor_index item must be a valid index into the constant_pool table. The constant_pool entry at that index must be a CONSTANT_Utf8_info structure which must represent a valid Java field descriptor.

attributes

public Attribute[] attributes

A field can have any number of attributes associated with it.

The only attributed defined for the attributes table of a field_info structure by this specification is the ConstantValue attribute.

print

public void print(PrintWriter pw,
                  int indent)

Pretty-print this field_info structure.
