GNU Info (python2.1-lib.info)Repr ObjectsRepr Objects ------------ `Repr' instances provide several members which can be used to provide size limits for the representations of different object types, and methods which format specific object types. `maxlevel' Depth limit on the creation of recursive representations. The default is `6'. `maxdict' `maxlist' `maxtuple' Limits on the number of entries represented for the named object type. The default for `maxdict' is `4', for the others, `6'. `maxlong' Maximum number of characters in the representation for a long integer. Digits are dropped from the middle. The default is `40'. `maxstring' Limit on the number of characters in the representation of the string. Note that the "normal" representation of the string is used as the character source: if escape sequences are needed in the representation, these may be mangled when the representation is shortened. The default is `30'. `maxother' This limit is used to control the size of object types for which no specific formatting method is available on the `Repr' object. It is applied in a similar manner as `maxstring'. The default is `20'. `repr(obj)' The equivalent to the built-in `repr()' that uses the formatting imposed by the instance. `repr1(obj, level)' Recursive implementation used by `repr()'. This uses the type of OBJ to determine which formatting method to call, passing it OBJ and LEVEL. The type-specific methods should call `repr1()' to perform recursive formatting, with `LEVEL - 1' for the value of LEVEL in the recursive call. `repr_TYPE(obj, level)' Formatting methods for specific types are implemented as methods with a name based on the type name. In the method name, TYPE is replaced by `string.join(string.split(type(OBJ).__name__, '_')'. Dispatch to these methods is handled by `repr1()'. Type-specific methods which need to recursively format a value should call `self.repr1(SUBOBJ, LEVEL - 1)'. automatically generated by info2www version 1.2.2.9 |
